Description

Technical Field

[0001] This application relates to the field of display technologies, and in particular, to a method, apparatus, device, medium, and product for light control. Background Art

[0002] In virtual application display scenarios, to improve the display effect, both product parameters and the performance of hardware devices have been significantly improved.

[0003] In practical applications, to improve the display effect, the frame rate, resolution, etc. are usually increased. At the same time, great improvements have also been made in the light quality effect, including an increase in the number of light sources and an increase in the light range, resulting in a significant increase in the cost of hardware devices. For example, the computing power and power consumption of a Graphics Processing Unit (GPU), the power consumption of a display screen, the power consumption of Double Data Rate (DDR) memory, and so on. This excessive consumption of power and computing power becomes an unnecessary burden for electronic devices in some cases. Therefore, a solution is needed to reduce the light cost while meeting the display requirements. Summary of the Invention

[0004] Multiple aspects of this application provide a method, apparatus, device, medium, and product for light control to solve the problem of excessive light cost during the light control process.

[0005] In a first aspect, an embodiment of this application provides a method for light control, including:

[0006] Responding to a scene light control request for reducing light cost in a virtual scene, and determining a light control strategy for a preset light source in the virtual scene;

[0007] Based on the light control strategy, generating target light parameters for adjusting the low-cost light effect of the preset light source;

[0008] Performing a light rendering task on the preset light source using the target light parameters.

[0009] After receiving a scene light control request for reducing light cost, it is possible to further generate, according to the light control strategy, target light parameters that can reduce the light cost while ensuring that the original light effect remains unchanged or basically unchanged, and then meet the display requirements of the virtual scene and the user's viewing and usage experience, effectively reducing the device power consumption and the load of related components.

[0010] Optionally, generating target lighting parameters for adjusting the low-cost lighting effect of the preset light source based on the lighting control strategy includes: generating the target lighting parameters for reducing the lighting cost based on a fixed control strategy or a dynamic control strategy, where the target lighting parameters include at least one of an attenuation parameter and a compensation parameter.

[0011] When determining the target lighting parameters, it is necessary to determine them according to the selected control strategy. The target lighting parameters mentioned here include at least one of an attenuation parameter and a compensation parameter. Among them, the attenuation parameter is used to narrow the lighting range, and the compensation parameter is used to increase the lighting brightness. When selecting the target lighting parameters, they can be selected according to actual needs. For example, if the lighting effect is not significantly affected after adjusting the attenuation parameter, the compensation parameter can be not adjusted or replaced. The target lighting parameters are more reasonably selected through the above solution.

[0012] Optionally, generating target lighting parameters for adjusting the low-cost lighting effect of the preset light source based on the lighting control strategy includes: when the determined lighting control strategy is a fixed control strategy, intercepting the lighting rendering instruction; determining the number of light sources and / or the type of light source based on the lighting rendering instruction; generating a fixed attenuation parameter for reducing the lighting range and a fixed compensation parameter for increasing the lighting brightness according to the number of light sources and / or the type of light source.

[0013] When calculating the attenuation parameter and the compensation parameter, it is necessary to determine according to the content included in the real-time intercepted rendering instruction. Specifically, the corresponding fixed attenuation parameter and fixed compensation parameter should be determined according to the number of light sources, the type of light source, etc. included in the rendering instruction. During the subsequent game execution process, there is no need to modify or adjust the attenuation parameter and the compensation parameter, avoiding frequent calculation of the attenuation parameter and the compensation parameter and reducing the computing power consumption.

[0014] Optionally, generating target lighting parameters for adjusting the low-cost lighting effect of the preset light source based on the lighting control strategy includes: when the determined lighting control strategy is a dynamic control strategy, intercepting the lighting rendering instruction and obtaining the device operating parameters; generating a dynamic attenuation parameter for reducing the lighting range and a dynamic compensation parameter for increasing the lighting brightness based on the lighting rendering instruction and the device operating parameters.

[0015] When calculating the attenuation parameter and the compensation parameter, it should be comprehensively determined according to the content included in the real-time intercepted rendering instruction and the device operating parameters. Specifically, the corresponding dynamic attenuation parameter and dynamic compensation parameter should be determined according to the number of light sources, the type of light sources included in the rendering instruction, and the device operating parameters. During the subsequent game execution, during the process of switching from the original lighting parameter to the target lighting parameter, the lighting parameter is finely adjusted frame by frame until the target lighting parameter is reached. Since the adjustment process is spread over multiple frames, the difference in lighting effects between two adjacent frames is very small, making the lighting effect transition in the whole adjustment process more natural and avoiding the situation of sudden changes that can be perceived by users. Thus, users can obtain a better viewing and usage experience.

[0016] Optionally, generating the dynamic attenuation parameter for reducing the lighting range and the dynamic compensation parameter for enhancing the lighting brightness based on the lighting rendering instruction and the device operating parameters includes: determining the number of light sources and / or the type of light sources based on the lighting rendering instruction; obtaining the graphics processor operating parameters and the device temperature parameter collected by the sensor; generating the dynamic attenuation parameter and the dynamic compensation parameter based on the number of light sources and / or the type of light sources, the graphics processor operating parameters, and the device temperature parameter.

[0017] When generating the corresponding lighting parameter based on the dynamic control strategy, it not only depends on the information included in the rendering instruction, but also on the device-related parameters input externally, including the graphics processor operating parameters (such as load, temperature, power consumption, etc.) and the device temperature parameter, and then comprehensively determines the dynamic attenuation parameter and the dynamic compensation parameter. These dynamic lighting parameters can be dynamically adjusted according to the rendering instruction and the externally input device-related parameters. Thus, it can better meet the lighting effect while reducing the lighting cost.

[0018] Optionally, generating the dynamic attenuation parameter and the dynamic compensation parameter based on the number of light sources and / or the type of light sources, the graphics processor operating parameters, and the device temperature parameter includes: determining the weight coefficients corresponding to the number of light sources and / or the type of light sources, the graphics processor operating parameters, and the device temperature parameter respectively; obtaining the total weight value obtained by summing up each weight coefficient; and selecting the dynamic attenuation parameter and the dynamic compensation parameter from the preset lighting parameter table according to the total weight value.

[0019] Optionally, the determination method of the dynamic compensation parameter includes: when the dynamic attenuation parameter is less than the first threshold, generating a compensation parameter greater than the first threshold corresponding to the attenuation parameter, so as to use the compensation parameter to enhance the light source brightness, and the enhanced light source brightness is not greater than the brightness entering the virtual scene.

[0020] By setting reasonable attenuation parameters, the lighting range can be reduced, thereby directly and significantly reducing the lighting cost. However, sometimes reducing the lighting range will cause a significant change in the lighting effect compared to the original lighting. To mitigate the change in the lighting effect, appropriate compensation parameters need to be selected to increase the light source brightness. That is, when calculating the lighting brightness, it needs to be comprehensively determined based on the impact caused by the attenuation parameters. In other words, the compensation parameters are calculated based on the attenuation parameters.

[0021] Optionally, after intercepting the lighting rendering instruction, it further includes: determining lighting model parameters based on the lighting rendering instruction; creating a copy of the lighting model based on the lighting model parameters for performing the lighting rendering task using the copy of the lighting model.

[0022] Performing the lighting rendering task on the preset light source using the target lighting parameters includes: replacing the historical lighting parameters in the copy of the lighting model with the target lighting parameters; binding the copy of the lighting model based on the rendering instruction; performing the lighting rendering task on the preset light source based on the copy of the lighting model.

[0023] In practical applications, to facilitate the adjustment of the lighting effect, a copy of the model is established for the original lighting model. When performing the rendering task, the copy of the lighting model is used to replace the original lighting model. At the same time, the target lighting parameters are used to replace the original lighting parameters. After completing the replacement task, the rendering task for the preset light source is performed. In this solution, the number of original light sources will not be changed because changing the number of light sources will make it easy for users to notice and even wrongly change the game plot.

[0024] Optionally, performing the lighting rendering task on the preset light source using the target lighting parameters includes: converting the target lighting parameters into code parameters executable by the shader; after adjusting the historical lighting model and historical lighting parameters in the shader using the code parameters, performing the lighting rendering task on the preset light source.

[0025] In an alternative solution, if no replacement of the lighting model copy and target lighting parameters is performed, the target lighting parameters can also be converted into code parameters and input into the shader at the stage when the shader executes the code task to achieve the modification of the execution effect of the rendering task for the preset light source.

[0026] Optionally, in response to a scene lighting control request in a virtual scene, determining a lighting control strategy for a preset light source in the virtual scene, including: if a scene lighting control request for reducing lighting cost triggered by a user is received, or a scene lighting control request for reducing lighting cost triggered by a preset default is read, then determining whether to select a default configuration according to a local configuration file; if so, determining that the lighting control strategy is a fixed control strategy; if not, determining that the lighting control strategy is a dynamic control strategy.

[0027] In a second aspect, an embodiment of the present application further provides a lighting control device, including:

[0028] A determination module, configured to determine a lighting control strategy for a preset light source in the virtual scene in response to a scene lighting control request for reducing lighting cost in the virtual scene;

[0029] A generation module, configured to generate target lighting parameters for adjusting a low-cost lighting effect of the preset light source based on the lighting control strategy;

[0030] An execution module, configured to execute a lighting rendering task for the preset light source by using the target lighting parameters.

[0031] In a third aspect, an embodiment of the present application provides an electronic device, which may include: a processor and a memory. The memory is used to store computer-executable program code, and the program code includes instructions; when the processor executes the instructions, the instructions cause the electronic device to execute the method in the first aspect.

[0032] In a fourth aspect, an embodiment of the present application provides a computer program product containing instructions, which, when running on a computer, causes the computer to execute the method in the first aspect above.

[0033] In a fifth aspect, an embodiment of the present application provides a computer-readable storage medium, in which instructions are stored, and when running on a computer, cause the computer to execute the method in the first aspect above.

[0034] In some embodiments of the present application, when a scene lighting control request for reducing lighting costs is received, the lighting control strategy of a preset light source in the corresponding virtual scene is further determined. According to the selected lighting control strategy, target lighting parameters for adjusting the low-cost lighting effect of the preset light source are generated, and then the lighting rendering task for the preset light source can be executed using the newly determined target lighting parameters. Through the above solution, when performing lighting rendering in a virtual scene, a suitable lighting control strategy is selected according to actual needs. Furthermore, based on the lighting control strategy, corresponding target lighting parameters for achieving a low-cost lighting effect are formulated, so that the lighting cost can be effectively reduced without reducing the lighting effect, including effectively reducing the graphics processor load, power consumption of the lighting, and overall power consumption of the electronic device, avoiding or reducing unnecessary rendering or over-rendering, and reducing the energy consumption loss caused during the lighting rendering process.

[0047] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part rather than all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0048] A Graphics Processing Unit (GPU) is a hardware device specifically designed to process graphics and image data. It is an important component in a computer system and is used to accelerate graphics rendering, image processing, and computing tasks. Compared with a Central Processing Unit (CPU), the GPU has more powerful performance in processing graphics and images. The GPU uses parallel computing, has a large number of processing units and dedicated graphics memory, and can process multiple image pixels and vertex data simultaneously. This enables the GPU to have wide applications in fields such as gaming, computer-aided design (CAD), scientific computing, and deep learning. The main functions of the GPU include graphics rendering, image processing, physical simulation, data parallel computing, etc. It can execute complex graphics algorithms such as ray tracing, shading, and texture mapping, enabling images to be presented on the screen at a faster speed and higher quality. In addition, the GPU can also perform tasks such as image and video encoding and decoding, image filtering, and image recognition.

[0049] A Lighting Model is a mathematical model used in computer graphics to simulate lighting effects. It describes how light interacts with objects and determines visual effects such as the brightness, color, and shadows of the object's surface. The lighting model usually considers three basic lighting components: ambient light, diffuse light, and specular light. Various lighting effects require corresponding light sources to be achieved.

[0050] A Light Source is an element used to simulate lighting effects. It is an important part of a game, used to create realistic lighting and shadow effects, enhancing the visual expressiveness of the game scene. In a game, a light source can be virtual, created and controlled by the game engine or developer. A light source can have various attributes and characteristics, such as range, brightness, color, position, type, etc. By adjusting the attributes and position of the light source, the brightness, color, and shadow effects of objects in the game scene can be changed, enhancing the realism and atmosphere of the scene.

[0051] In practical applications, when performing lighting rendering on a light source in a virtual scene, the graphics processing unit often needs to consume a large amount of computing power to achieve the required lighting effects. Especially when the frame rate of the game is high, the graphics processing unit sometimes has difficulty meeting the graphics rendering requirements, and there may be a lag situation. In addition, components such as the graphics processing unit, central processing unit, and display module in an electronic device will consume a large amount of electrical energy and generate a relatively high amount of heat, seriously affecting the stability and battery life of the electronic device. Therefore, there is a need to solve the problem of how to reduce lighting costs (including reducing the computing power of the graphics processing unit, power consumption, power consumption of the display module, and temperature of the electronic device) while ensuring the lighting effect.

[0052] The following will, with reference to the accompanying drawings, elaborate on the technical solutions provided by each embodiment of this application.

[0074] The modulation and demodulation processor may include a modulator and a demodulator. Among them, the modulator is used to modulate the low-frequency baseband signal to be transmitted into a medium-high frequency signal. The demodulator is used to demodulate the received electromagnetic wave signal into a low-frequency baseband signal. Subsequently, the demodulator transmits the demodulated low-frequency baseband signal to the baseband processor for processing. After being processed by the baseband processor, the low-frequency baseband signal is transmitted to the application processor. The application processor outputs a sound signal through an audio device (not limited to the speaker 170A, receiver 170B, etc.), or displays an image or video through the display screen 194. In some embodiments, the modulation and demodulation processor may be an independent device. In other embodiments, the modulation and demodulation processor may be independent of the processor 110 and disposed in the same device as the mobile communication module 150 or other functional modules.

[0079] The electronic device 100 can implement the shooting function through the ISP, the camera 193, the video codec, the GPU, the display screen 194, and the application processor, etc.

[0080] The ISP is used to process the data fed back by the camera 193. For example, when taking a photo, the shutter is opened, and the light passes through the lens and is transmitted to the camera photosensitive element. The optical signal is converted into an electrical signal, and the camera photosensitive element transmits the electrical signal to the ISP for processing and converts it into an image visible to the naked eye. The ISP can also perform algorithm optimization on the noise, brightness, and skin color of the image. The ISP can also optimize parameters such as the exposure and color temperature of the shooting scene. In some embodiments, the ISP can be set in the camera 193.

[0081] The camera 193 is used to capture static images or videos. The object generates an optical image through the lens and projects it onto the photosensitive element. The photosensitive element can be a charge-coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, and then transmits the electrical signal to the ISP to convert it into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in standard RGB, YUV, etc. formats. In some embodiments, the electronic device 100 may include one or N cameras 193, where N is a positive integer greater than 1.

There are many types of pressure sensors 180A, such as resistive pressure sensors, inductive pressure sensors, capacitive pressure sensors, etc. The capacitive pressure sensor may include at least two parallel plates having conductive materials. When a force acts on the pressure sensor 180A, the capacitance between the electrodes changes. The electronic device 100 determines the intensity of the pressure according to the change in capacitance. When a touch operation acts on the display screen 194, the electronic device 100 detects the intensity of the touch operation according to the pressure sensor 180A. The electronic device 100 can also calculate the position of the touch according to the detection signal of the pressure sensor 180A. In some embodiments, touch operations acting on the same touch position but with different touch operation intensities may correspond to different operation instructions. For example: when a touch operation with a touch operation intensity less than the first pressure threshold acts on the short message application icon, the instruction to view the short message is executed.

For example, touch operations acting on different applications (such as taking pictures, audio playing, etc.) can correspond to different vibration feedback effects. Touch operations acting on different regions of the display screen 194 can also correspond to different vibration feedback effects for the motor 191. Different application scenarios (such as time reminder, receiving information, alarm clock, game, etc.) can also correspond to different vibration feedback effects. The touch vibration feedback effect can also support customization.

The SIM card can be inserted into or removed from the SIM card interface 195 to achieve contact with and separation from the electronic device 100. The electronic device 100 can support one or N SIM card interfaces, where N is a positive integer greater than 1. The SIM card interface 195 can support Nano SIM cards, Micro SIM cards, SIM cards, etc. Multiple cards can be inserted into the same SIM card interface 195 at the same time. The types of the multiple cards can be the same or different. The SIM card interface 195 can also be compatible with different types of SIM cards.

In some embodiments, the electronic device 100 uses an eSIM, that is, an embedded SIM card. The eSIM card can be embedded in the electronic device 100 and cannot be separated from the electronic device 100.

[0109] The software system of the electronic device 100 can adopt a layered architecture, an event-driven architecture, a microkernel architecture, a microservices architecture, or a cloud architecture. In the embodiments of the present invention, the Android system with a layered architecture is taken as an example to exemplarily illustrate the software structure of the electronic device 100.

[0110] Figure 2 It is a software structure block diagram of the electronic device 100 in the embodiments of the present invention.

[0111] The layered architecture divides the software into several layers, and each layer has a clear role and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, from top to bottom, namely the application layer, the application framework layer, the Android runtime and system libraries, and the kernel layer.

[0112] The application layer may include a series of application packages.

[0113] As Figure 2 shown, the application packages may include applications such as a camera, a gallery, a calendar, a call, a map, a navigation, a WLAN, a Bluetooth, music, a video, a short message, etc.

[0114] The application framework layer provides application programming interfaces (APIs) and programming frameworks for the applications in the application layer. The application framework layer includes some predefined functions.

[0115] As Figure 2 shown, the application framework layer may include a window manager, a content provider, a view system, a telephone manager, a resource manager, a notification manager, etc.

[0116] The window manager is used to manage window programs. The window manager can obtain the display screen size, determine whether there is a status bar, lock the screen, capture the screen, etc.

[0117] The content provider is used to store and obtain data, and make this data accessible to application programs. The data may include videos, images, audio, incoming and outgoing calls, browsing history and bookmarks, phone books, etc.

[0118] The view system includes visual controls, such as controls for displaying text, controls for displaying pictures, etc. The view system can be used to build application programs. The display interface can be composed of one or more views. For example, a display interface including a text message notification icon may include a view for displaying text and a view for displaying pictures.

[0119] The phone manager is used to provide the communication function of the electronic device 100. For example, the management of call states (including connection, disconnection, etc.).

[0120] The resource manager provides various resources for application programs, such as localized strings, icons, pictures, layout files, video files, etc.

[0121] The notification manager enables application programs to display notification information in the status bar. It can be used to convey message types that need to be informed. It can disappear automatically after a short stay without user interaction. For example, the notification manager is used to inform that the download is completed, message reminders, etc. The notification manager can also be a notification that appears in the system top status bar in the form of a chart or scroll bar text, such as the notification of a background running application program, and can also be a notification that appears on the screen in the form of a dialogue window. For example, it prompts text information in the status bar, emits a prompt sound, the electronic device vibrates, the indicator light flashes, etc.

[0122] Android Runtime includes core libraries and a virtual machine. Android runtime is responsible for the scheduling and management of the Android system.

[0123] The core libraries contain two parts: one part is the functional functions that need to be called by the Java language, and the other part is the core libraries of Android.

[0124] The application layer and the application framework layer run in the virtual machine. The virtual machine executes the Java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as the management of object life cycles, stack management, thread management, security and exception management, and garbage collection.

[0125] The system library may include multiple functional modules. For example: surface manager, Media Libraries, 3D graphics processing library (such as: OpenGL ES), 2D graphics engine (such as: SGL), etc.

[0126] The surface manager is used to manage the display subsystem and provides the fusion of 2D and 3D layers for multiple applications.

[0127] The media library supports the playback and recording of various common audio and video formats, as well as static image files, etc. The media library can support multiple audio and video coding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

[0128] The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, synthesis, and layer processing, etc.

[0129] The 2D graphics engine is a drawing engine for 2D drawing.

[0130] The kernel layer is the layer between hardware and software. The kernel layer at least includes a display driver, a camera driver, an audio driver, and a sensor driver.

[0131] The following combines the capture and photo-taking scenario to exemplarily illustrate the working processes of the software and hardware of the electronic device 100.

[0132] When the touch sensor 180K receives a touch operation, the corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the touch operation into a raw input event (including information such as touch coordinates and the timestamp of the touch operation). The raw input event is stored in the kernel layer. The application framework layer obtains the raw input event from the kernel layer and identifies the control corresponding to the input event. Taking the touch operation as a touch click operation and the control corresponding to the click operation as the control of the camera application icon as an example, the camera application calls the interface of the application framework layer to start the camera application, and then starts the camera driver by calling the kernel layer, and captures a static image or video through the camera 193.

[0133] Figure 3 It is a schematic flowchart of the light control method provided by an exemplary embodiment of the present application. As Figure 3 shown, the execution subject of this method can be an electronic device of a user terminal, and this electronic device can be used in light control scenarios in games, light control scenarios in home design applications, light control scenarios in modeling applications, light control scenarios in augmented reality applications, and light control scenarios in virtual display applications, etc. For the sake of easy understanding, the following embodiments will be described by taking the light control scenario in a game as an example. Specifically, it includes the following steps:

[0134] Step 301: In response to a scene lighting control request for reducing lighting costs in a virtual scene, determine a lighting control strategy for a preset light source in the virtual scene.

[0135] Step 302: Based on the lighting control strategy, generate target lighting parameters for adjusting the low-cost lighting effect of the preset light source.

[0136] Step 303: Use the target lighting parameters to perform a lighting rendering task on the preset light source.

[0137] Taking a game virtual scene as an example, in a game application scenario, there are not only virtual objects that can be manipulated by users (such as virtual characters, virtual animals, virtual weapons, virtual vehicles, etc.), but also many virtual environment contents, such as virtual plants, virtual landscapes, virtual lights, etc. in the virtual environment. Due to some plot requirements, many light sources are set to make the game scene more realistic and users obtain a better game experience.

[0138] When the number of light sources is relatively large, the graphics processor needs to render them one by one, and the computing power cost of the graphics processor is relatively high. Sometimes it even affects the overall game rendering smoothness effect. For example, the game screen may freeze, etc., directly affecting the user experience. In addition, the power consumption of the graphics processor will also be relatively high, affecting the battery life of the electronic device.

[0139] Therefore, according to the actual situation, it is possible to reduce the lighting cost as much as possible while maintaining the original lighting effect. The reduction of lighting cost mentioned here includes reducing the load of the graphics processing unit (GPU), reducing the power consumption of the electronic device (including reducing the power consumption of the GPU and the display module), etc.

[0140] The preset light source mentioned here refers to the number of light sources, light source types, etc. set according to the game plot requirements in the game scene. When controlling and adjusting the lighting effect, ensure that the number of light sources remains unchanged, that is, the lighting effect required by the original game plot will not be changed.

[0141] For example, when the game is just started, it will be rendered and displayed according to the established parameters. When entering the game scene, it will be adjusted to a low-cost lighting effect according to the need. It should be noted that when adjusting the lighting effect, in order to reduce the difference before and after adjustment, it is necessary to comprehensively determine the target lighting parameters, that is, to maintain the original lighting effect and reduce the lighting cost at the same time. How to determine the required target lighting parameters will be explained through specific embodiments below, and will not be repeated here.

[0142] The low-cost lighting effect mentioned here can be understood as having a lower lighting implementation cost for achieving the same or similar lighting effects. Specifically, on the basis of ensuring the same number of light sources, the lighting range of one or more light sources can be appropriately reduced, so as to reduce the GPU load, power consumption, and power consumption of the display module, etc. To mitigate or avoid the negative impact of reducing the lighting range on the lighting effect (for example, directly affecting the user's game experience), the brightness of one or more light sources can be specifically increased, so as to effectively reduce the visual deviation before and after adjustment, making it difficult for users to notice that the lighting parameters have been adjusted, or even if they can see that the lighting effect has been adjusted, it will not affect the overall user experience. Of course, if the impact on the lighting effect is not obvious after reducing the lighting range of one or more light sources, the brightness of one or more light sources may not be increased.

[0143] There can be various ways to generate the scene lighting control request for reducing the lighting cost mentioned here. For example, in an electronic device, the lighting cost of all light sources in the game can be set to be reduced by default for the game, or the scene lighting control request can be triggered when the user clearly indicates that the game effect (including the lighting cost in the game scene) needs to be reduced. It can also be automatically or manually triggered when the electronic device reaches certain conditions (such as the mobile phone battery level is lower than 50%, the game energy consumption is greater than 10%, the GPU load reaches 80%, and the mobile phone temperature reaches 40°C). The scene lighting control request can also be triggered according to the game plot or game scene. For example, when the number of light sources in the game scene is greater than a certain number threshold (when the number of light sources is greater than 10), when the game plot is a close-up shot (such as highlighting the protagonist), aiming shot, ultimate move confrontation, etc., and the user's attention is not on the game background environment.

[0144] Through the above solution, after receiving the scene lighting control request for reducing the lighting cost in the virtual scene, the lighting control strategy for the preset light source in the virtual scene is further determined. When selecting the lighting parameters, according to the specific lighting control strategy, the target lighting parameters for adjusting the low-cost lighting effect of the preset light source are generated. On the premise of changing or slightly changing the original lighting effect, the lighting implementation cost is significantly reduced, that is, the lighting range is reduced, so as to achieve the purpose of reducing the load of the graphics processing unit (GPU), GPU power consumption, and power consumption of the display module.

[0145] In one or more embodiments of the present application, generating the target lighting parameters for adjusting the low-cost lighting effect of the preset light source based on the lighting control strategy includes: generating the target lighting parameters for reducing the lighting cost based on a fixed control strategy or a dynamic control strategy, and the target lighting parameters include at least one of an attenuation parameter and a compensation parameter.

[0146] In practical applications, there can be various lighting control strategies, including fixed control strategies and dynamic control strategies. Among them, the fixed control strategy can be understood as the final determined target lighting parameters being fixed and remaining so throughout the game, without any process of gradual adjustment of the lighting effect. The "fixed" here can be absolute fixation, that is, the lighting ranges and lighting intensities of all light sources in the game scene are the same and fixed; it can also be relative fixation, that is, in the game scene, different lighting parameters can be set according to different light source types, and once determined, they will not change during the game process.

[0147] The dynamic control strategy can be understood as the target lighting parameters being adjusted in real time and dynamically, which can be adjusted according to the game plot, according to the load situation, according to the power consumption, and can also be slowly adjusted frame by frame from the original parameters and finally adjusted to the target lighting parameters.

[0148] In the solution of this application, the target lighting parameters include attenuation parameters and compensation parameters. Among them, the role of the attenuation parameter is to adjust the size of the original lighting model (the size of the lighting model is reflected by the range of model vertex coordinates. In other words, if you want to adjust the size of the lighting model, it can be understood as adjusting the coordinates of the vertices of the lighting model), as well as the size of the corresponding initial lighting intensity Uniform parameter value, so as to be able to adjust the size of the lighting range, which is equivalent to shrinking the input, and thus finally changing the computing power, load, and power consumption required for the same lighting effect of the output.

[0149] For example, the size of the model can be changed by performing a scaling operation on the model in the rendering pipeline. Before rendering, multiply the vertex coordinates of the model by a scaling factor to change the size of the model. This will affect both the geometry and the lighting effect of the model at the same time. By scaling the model to change its size, during the rendering process, the GPU needs to calculate and process fewer pixels. A smaller model means a smaller vertex range, thus reducing the amount of data and the amount of calculation that the GPU needs to process. Therefore, the computing power required for rendering will be reduced accordingly.

[0150] Figure 4a It is a schematic diagram of the lighting parameter effect corresponding to a fixed control strategy provided by an embodiment of this application. From Figure 4a it can be seen that before adjustment, the model corresponding to the lamp has a larger range of vertices. After scaling it using the attenuation coefficient, the new model of the lamp obtained has a smaller vertex range. This means that the model size is reduced, and the corresponding GPU rendering workload is also reduced, thus being able to reduce the GPU load, reduce the power consumption, and improve the battery life of the electronic device.

[0151] The compensation parameter mentioned here is used to adjust the brightness level of the light source. Increasing the brightness compensation parameter will make the light source brighter, and decreasing the brightness compensation parameter will make the light source darker. For example, increasing the brightness compensation parameter can increase the brightness value of each pixel by a fixed offset. In practical applications, the adjustment of the compensation parameter is not necessary. If the overall effect of the game is not significantly affected after adjusting the attenuation parameter, the compensation parameter can be left unadjusted. Conversely, if the user can clearly see the adjustment after adjusting the attenuation parameter, and it even affects the user's gaming experience, then the compensation parameter needs to be adjusted to reduce the negative impact on the overall game display effect caused by adjusting the attenuation parameter.

[0152] It should be noted that the compensation parameter is to make up for the negative impact brought by the attenuation parameter. Therefore, when determining the target lighting parameter, it is necessary to first determine the attenuation parameter, and then further determine the appropriate compensation parameter that can make up for the negative impact brought by the attenuation parameter according to the influence of the attenuation parameter on the lighting effect. When the attenuation parameter is a dynamically adjustable parameter, the corresponding compensation parameter also needs to be adjusted dynamically. The specific adjustment method will be described in detail in the following embodiments and will not be repeated here.

[0153] Based on the foregoing embodiments, generating the target lighting parameter for adjusting the low-cost lighting effect of the preset light source based on the lighting control strategy includes:

[0154] When the determined lighting control strategy is a fixed control strategy, intercept the lighting rendering instruction;

[0155] Based on the lighting rendering instruction, determine the number of light sources and / or the type of light source;

[0156] According to the number of light sources and / or the type of light source, generate a fixed attenuation parameter for reducing the lighting range and a fixed compensation parameter for enhancing the lighting brightness.

[0157] The lighting rendering instruction mentioned here is an instruction or function used to implement the lighting effect, which is used to calculate the lighting intensity and color on the surface of objects in the scene to simulate the lighting effect in the real world. The role of the lighting rendering instruction is to determine the brightness, reflection, refraction and other optical effects on the object surface, so as to make the rendering result more realistic. The lighting rendering instruction usually includes lighting model parameters, light source parameters, etc. Among them, the lighting model refers to a three-dimensional model composed of a bunch of coordinate vertices. For example, the physical model of lighting drawing is divided into spherical, conical, hemispherical, cylindrical, etc. from 3D features. Therefore, the accurate description should be the Mesh model of the light source, and the attenuation in the solution is also adjusted according to the corresponding size of the three-dimensional Mesh model. The lighting attenuation coefficient is the change coefficient applied to the Mesh model and the lighting intensity. Because the lighting is attenuated from the final effect, it can reduce the GPU load and power consumption.

[0158] Light source parameters are used to describe attributes such as the type, position, color, and intensity of a light source. The type of light source can be different types such as a point light source, a directional light source, or a spot light. By adjusting the parameters of the light source, the direction, intensity, range, brightness, and color of the illumination can be changed, thereby affecting the illumination effect on the object surface. Among them, the illumination range and the number of light sources have a relatively obvious impact on the graphics processor load.

[0159] In addition, the illumination model can also be the Lambert illumination model, the Blinn-Phong illumination model, the Phong illumination model, etc. These models define the calculation methods for effects such as light attenuation, diffuse reflection, and specular reflection. Correspondingly, the attenuation parameter is used to simulate the attenuation effect of light during propagation. The light will gradually weaken at positions farther away from the light source, and the attenuation parameter controls the way and degree of this attenuation. The attenuation parameter is usually related to the type and intensity of the light source and is used to calculate the attenuation coefficient of the light during propagation. The attenuation coefficient represents the degree to which the light intensity weakens as the distance increases. Common attenuation models include linear attenuation, quadratic attenuation, and inverse-square attenuation. By adjusting the value of the attenuation parameter, the attenuation degree of the light during propagation can be controlled, that is, it can be used to adjust the size of the illumination range of the light source. During the rendering process of the same light source, the larger the illumination range, the greater the GPU load and power consumption, and the smaller the illumination range, the smaller the GPU load and power consumption. Therefore, a low-cost illumination effect can be achieved by adjusting or selecting an appropriate attenuation parameter, that is, reducing the illumination cost.

[0160] The attenuation coefficient corresponding to the above illumination model is used to simulate the effect of the light gradually weakening during propagation. It determines the rate at which the light attenuates as the distance increases, thereby affecting the illumination intensity received by the object surface. The illumination attenuation coefficient is usually calculated using a formula, and the two most common methods are linear attenuation and quadratic attenuation.

[0161] For example, linear attenuation: Linear attenuation is the simplest attenuation method, which assumes that the intensity of the light is linearly related to the distance. Determining the specific value of the illumination attenuation coefficient usually requires adjustment according to the actual requirements of the scene and the characteristics of the light source. A larger attenuation coefficient will cause the light to attenuate faster at a shorter distance, while a smaller attenuation coefficient will allow the light to propagate farther. By adjusting the attenuation coefficient, the illumination range can be controlled to achieve the desired illumination effect. The attenuation coefficient can be calculated using the following formula:

[0162] Attenuation=1 / (Constant+Linear*Distance)

[0163] Among them, Constant, Linear, and Distance are the constant, linear term, and distance respectively. Constant is used to control the constant attenuation part, Linear is used to control the linear attenuation part, and Distance represents the propagation distance of light. Therefore, at least one parameter in the above calculation formula can be adjusted according to actual needs. For example, the Distance distance parameter is multiplied by the reciprocal of the number of light sources (1 / N, where N represents the number of light sources), thereby narrowing the illumination range. In addition, the type of light source can also be considered. For example, a point light source can be multiplied by twice the reciprocal of the number of light sources, and other light sources can be multiplied by the reciprocal of the number of light sources. In practical applications, adjustments can be made according to needs. Here, it is only for illustrative purposes and does not constitute a limitation to the technical solution of this application. Generally speaking, the more the number of light sources, the more obvious the reduction of the illumination range.

[0164] Such as Figure 4b is a schematic diagram of the effect of the illumination parameters corresponding to another fixed control strategy provided by the embodiment of the present application. As can be seen from Figure 4b , the illumination range is represented by the length of the light ray, and the brightness of the light is represented by the thickness of the light ray. In the current game screen, there are virtual characters and a virtual background environment. In the virtual background environment, buildings can be seen, and multiple lighting fixtures are hung on the buildings. Before adjusting the illumination parameters, the illumination ranges of each fixture are relatively large, and the illumination ranges of each fixture overlap. After adjusting the illumination parameters, the illumination ranges of each fixture are relatively small, and there is no intersection between the illumination ranges of adjacent fixtures. At the same time, as can also be seen from Figure 4b , the brightness before adjustment is relatively low (that is, Figure 4b the light ray lines in Figure 4b are thinner), and the brightness increases after adjustment (that is,

[0165] such as Figure 5 is a schematic diagram of the effect of the illumination parameters corresponding to yet another fixed control strategy provided by the embodiment of the present application. As can be seen from Figure 5 , in the current game screen, there are virtual characters and a virtual background environment. In the virtual background environment, buildings can be seen, and multiple lighting fixtures are hung on the buildings. Before adjusting the illumination parameters, the illumination ranges of each fixture are relatively large, and the illumination ranges of each fixture overlap. After adjusting the illumination parameters, the illumination ranges of multiple fixtures are adjusted at intervals. The illumination ranges of the adjusted fixtures are relatively small, and there is no intersection between the illumination ranges of adjacent fixtures. At the same time, as can also be seen from Figure 5 the brightness before adjustment is relatively low (that is, Figure 5 the light ray lines in Figure 5 are thicker).

[0166] Through the above solution, the target lighting parameters finally determined based on the number of light sources and / or the type of light sources can adjust the lighting range, effectively reduce the load and power consumption of the graphics processor, and thus effectively achieve a low-cost lighting effect. In addition, the target lighting parameters in the above embodiments are fixed and do not need to be adjusted during the game, which can effectively reduce the lighting rendering frequency and the amount of calculation.

[0167] In one or more embodiments of the present application, as Figure 6 is a schematic flowchart of a method for determining target lighting parameters based on a dynamic lighting control strategy provided by an embodiment of the present application. As can be seen from Figure 6 it, generating target lighting parameters for adjusting the low-cost lighting effect of the preset light source based on the lighting control strategy includes:

[0168] Step 601: When the determined lighting control strategy is a dynamic control strategy, intercept the lighting rendering instruction and obtain the device operating parameters.

[0169] Step 602: Based on the lighting rendering instruction and the device operating parameters, generate a dynamic attenuation parameter for reducing the lighting range and a dynamic compensation parameter for enhancing the lighting brightness.

[0170] Among them, the specific implementation process of generating a dynamic attenuation parameter for reducing the lighting range and a dynamic compensation parameter for enhancing the lighting brightness in step 602 based on the lighting rendering instruction and the device operating parameters includes:

[0171] Step 6021: Based on the lighting rendering instruction, determine the number of light sources and / or the type of light sources.

[0172] Step 6022: Obtain the operating parameters of the graphics processor and collect the device temperature parameters using a sensor.

[0173] Step 6023: Based on the number of light sources and / or the type of light sources, the operating parameters of the graphics processor, and the device temperature parameters, generate the dynamic attenuation parameter and the dynamic compensation parameter.

[0174] The lighting rendering instructions mentioned here are instructions or functions used to achieve lighting effects, which are used to calculate the lighting intensity and color on the surface of objects in a scene to simulate the lighting effects in the real world. The role of the lighting rendering instructions is to determine the brightness, reflection, refraction and other optical effects on the surface of objects, so that the rendering results are more realistic. Lighting rendering instructions usually include lighting model parameters, light source parameters, etc. Among them, the lighting model parameters are used to describe the way light interacts with the object surface. Common lighting models include the Lambert lighting model, the Blinn-Phong lighting model, and the Phong lighting model, etc. These models define the calculation methods for effects such as light attenuation, diffuse reflection, and specular reflection.

[0175] Light source parameters are used to describe the properties of the light source, such as the type, position, color, and intensity of the light source. The light source type can be different types such as point light source, parallel light source, or spotlight. By adjusting the parameters of the light source, the direction, intensity, range, brightness, and color of the light can be changed, thereby affecting the lighting effect on the object surface. Among them, the lighting range and the number of light sources have a relatively obvious impact on the graphics processor load.

[0176] The light attenuation coefficient is used to simulate the effect of light gradually weakening during propagation. It determines the rate at which light attenuates as the distance increases, thereby affecting the lighting intensity received by the object surface. The light attenuation coefficient is usually calculated using a formula, and the most common are the linear attenuation and quadratic attenuation methods.

[0177] For example, linear attenuation: Linear attenuation is the simplest attenuation method, which assumes that the intensity of the light is linearly related to the distance. Determining the specific value of the light attenuation coefficient usually requires adjustment according to the actual needs of the scene and the characteristics of the light source. A larger attenuation coefficient will cause the light to attenuate faster at a shorter distance, while a smaller attenuation coefficient will allow the light to travel farther. By adjusting the attenuation coefficient, the lighting range can be controlled to achieve the desired lighting effect. The attenuation coefficient can be calculated using the following formula:

[0178] Attenuation=1 / (Constant+Linear*Distance)

[0179] Among them, Constant, Linear, and Distance are the constant, linear term, and distance respectively. Constant is used to control the constant attenuation part, Linear is used to control the linear attenuation part, and Distance represents the propagation distance of light. Therefore, at least one parameter in the above calculation formula can be adjusted according to actual needs. For example, the Distance distance parameter is multiplied by the reciprocal of the number of light sources (1 / N, where N represents the number of light sources), thereby narrowing the illumination range. In addition, the type of light source can also be considered. For example, a point light source can be multiplied by the reciprocal of twice the number of light sources, and other light sources can be multiplied by the reciprocal of the number of light sources. In practical applications, it can be adjusted according to needs. Here, it is only for illustrative purposes and does not constitute a limitation on the technical solution of this application. Generally speaking, the more the number of light sources, the more obvious the reduction of the illumination range.

[0180] Furthermore, the influence of device operating parameters is also considered. Specifically, the GPU utilization rate (for example, the GPU utilization rate reaches 70%) can be used as the coefficient for multiplying the Distance distance parameter, and the device temperature parameter can also be used as the coefficient for multiplying the Distance distance parameter. For example, when the device temperature parameter is 30°C, the corresponding coefficient is 1, and when it is 40°C, the corresponding coefficient is 1.5, etc. Here, it is only for illustrative purposes. In practical applications, it can be adaptively adjusted according to needs and the attenuation coefficient calculation formula. It should be noted that the more the number of light sources, the more the illumination range is reduced; the higher the GPU utilization rate, the more the illumination range is reduced; the higher the device temperature parameter, the more the illumination range is reduced.

[0181] Such as Figure 7 is a schematic diagram of the effect of the illumination parameters corresponding to the dynamic control strategy provided by the embodiment of this application. From Figure 7 it can be seen that there are virtual characters and a virtual background environment displayed in the current game screen. In the virtual background environment, buildings can be seen, and there are multiple lighting fixtures hanging on the buildings. Before adjusting the illumination parameters, the illumination ranges of each fixture are relatively large, and the illumination ranges of each fixture overlap with each other. During the process of adjusting the illumination parameters, it is adjusted in multiple frames. In each frame, the illumination range is reduced a little, and at the same time, the illumination brightness is increased a little, gradually adjusting the illumination range so that the illumination ranges of each fixture are relatively small, and there is no intersection between the illumination ranges of adjacent fixtures, and at the same time, the illumination brightness reaches the expected standard.

[0182] It should be noted that in addition to the device temperature parameter and the graphics processor operating parameters (GPU load, utilization rate, temperature) mentioned above, the device operating parameters can also include parameters such as game power consumption and remaining battery power of the electronic device.

[0183] Through the above solution, the target lighting parameters determined based on the number and / or type of light sources, as well as the graphics processor load, device temperature parameters, etc. can achieve the adjustment of the lighting range, effectively reduce the load and power consumption of the graphics processor, and thus effectively achieve a low-cost lighting effect. In addition, the target lighting parameters in the above embodiments are dynamically changed, which can effectively reduce the impact of lighting parameter adjustment on the lighting effect, making the adjustment process less noticeable to users and not affecting the user's gaming experience.

[0184] Next, how to determine the dynamic attenuation parameter and the dynamic compensation parameter will be specifically described. Generating the dynamic attenuation parameter and the dynamic compensation parameter based on the number and / or type of light sources, the graphics processor working parameters, and the device temperature parameters includes: determining the weight coefficients corresponding to the number of light sources and / or the type of light source, the graphics processor working parameters, and the device temperature parameters respectively; obtaining the total weight value based on the sum of each of the weight coefficients; and selecting the dynamic attenuation parameter and the dynamic compensation parameter from a preset lighting parameter table according to the total weight value.

[0185] There are many factors affecting the lighting parameters, including GPU load, GPU frequency, device temperature parameters, and the number of real-time light sources. Among them, the GPU load and device temperature parameters are external input factors, and the number of real-time light sources is obtained by counting through the rendering instruction interception method. Each influencing factor has a fixed weight coefficient kn. Multiply the values of all N influencing factors by the corresponding weight coefficient kn and accumulate them to obtain the total weight value R.

[0186] In the algorithm, M different attenuation and compensation coefficient levels are preset in advance. At the same time, a lighting parameter table is also preset for different levels. According to the size of the total weight value R, select different coefficient levels by looking up the table, and change the attenuation and compensation coefficient values in effect for the current solution in real time. The algorithm performs a dynamic decision calculation process every fixed N frames.

[0187] Since there are significant differences in the coefficient values between different gears, switching the scenario coefficients in real time during the game will cause sudden changes in the lighting effect, reducing the user's gaming experience. Therefore, in the implementation of the coefficient scheme for dynamic decision-making, a switching method with gradual coefficient change is introduced. Specifically, according to a preset gradual change slope (fixed value / N frames), the difference between the currently used lighting parameters and the target lighting parameters is calculated. Then, the difference is divided by the gradual change slope to obtain the number of frames for gradual change. In each frame, the difference is divided by the number of frames for gradual change to obtain the step size for gradual change, and then the coefficient is gradually increased by the step size for gradual change in each frame until the target lighting parameters are reached. In this way, an adaptive gradual adjustment of the lighting effect is achieved. According to multiple influencing factors and corresponding weight coefficients in the system, a threshold coefficient is calculated to select an appropriate gear for attenuation and compensation. To avoid sudden changes in the lighting effect, a switching method with gradual coefficient change is introduced, and the coefficient value is gradually adjusted in each frame to achieve smooth transition and adaptive adjustment of the lighting effect. This can improve the user's gaming experience and ensure the continuity and stability of the lighting effect in different scenarios.

[0188] After determining the dynamic attenuation parameter, the dynamic compensation parameter can be further determined, specifically including: when the dynamic attenuation parameter is less than the first threshold, a compensation parameter greater than the first threshold corresponding to the attenuation parameter is generated, so as to use the compensation parameter to increase the brightness of the light source, and the increased brightness of the light source is not greater than the brightness entering the virtual scene.

[0189] For example, when the light attenuation coefficient is less than 1, a compensation coefficient is usually introduced. This compensation coefficient is a value greater than 1 and corresponding to the attenuation coefficient. The compensation coefficient is multiplied by the RGB values of the light source respectively to increase the overall brightness of the light source. The purpose of this is to compensate for the light effect after the attenuation coefficient is adjusted by the foregoing solution, reduce the brightness difference between the overall game screen and the original screen after the solution, and thus improve the picture quality experience. Specifically, when the light attenuation coefficient is less than 1, it means that the light will gradually weaken during propagation, the light propagation distance becomes shorter, and the range becomes smaller. In order to maintain the brightness balance of the screen, a compensation coefficient needs to be introduced to increase the brightness of the light source. This can make up for the brightness loss caused by the attenuation effect and ensure that the brightness between the screen after the solution is processed and the original screen is consistent. By multiplying the compensation coefficient by the RGB values of the light source, the brightness of the entire light source can be increased, so as to achieve the effect of compensating for the light after attenuation. This compensation can reduce the brightness difference between the overall game screen and the original screen after the solution, improve the picture quality experience, and enable players to obtain a more realistic and comfortable visual experience in the game. By introducing the compensation coefficient and multiplying it by the RGB values of the light source, the light after attenuation by the solution can be compensated for its effect when the light attenuation coefficient is less than 1, so as to reduce the picture brightness difference and improve the picture quality experience. This compensation mechanism can ensure the overall brightness consistency of the game screen under different lighting conditions and provide better visual effects.

[0190] In one or more embodiments of the present application, after intercepting the light rendering instruction, it further includes: determining light model parameters based on the light rendering instruction; creating a copy of the light model based on the light model parameters, so as to execute the light rendering task using the copy of the light model.

[0191] In order to determine the light model parameters, it is first necessary to select a light model suitable for the current application scenario. Common light models include the classic Phong model, Blinn-Phong model, Lambert model, etc. Each light model has a set of parameters for defining the calculation method and characteristics of the light effect.

[0192] After determining the light model parameters, a copy of the light model can be created. The copy of the light model is an instance based on the light model parameters and is used to execute the light rendering task. By using the copy of the light model, the light model can be modified and adjusted during the rendering process to achieve different light effects.

[0193] The copy of the light model can be used to execute various light rendering tasks, such as real-time rendering, offline rendering, game rendering, etc. According to specific application requirements, the parameters of the copy of the light model can be set, the light source can be configured, and the material properties can be adjusted to achieve the required light effect.

[0194] Determining the lighting model parameters is to select a lighting model suitable for the application scenario and define its parameters. Creating a copy of the lighting model is an instance based on the lighting model parameters and is used to perform the lighting rendering task. The copy of the lighting model can be parameter - set and adjusted according to requirements to achieve the desired lighting effect.

[0195] There are two ways to perform the lighting rendering task on the preset light source based on the target lighting parameters. One is by using the method of model replacement and parameter replacement, specifically including:

[0196] Using the target lighting parameters to replace the historical lighting parameters in the copy of the lighting model;

[0197] Binding the copy of the lighting model based on the rendering instruction;

[0198] Performing the lighting rendering task on the preset light source based on the copy of the lighting model.

[0199] Replacing the historical lighting parameters in the copy of the lighting model: According to the target lighting parameters, replace the historical lighting parameters in the copy of the lighting model. This can ensure that the copy of the lighting model uses the latest lighting parameters for rendering.

[0200] The historical lighting parameters mentioned here can be understood as the original lighting parameters in the copy of the lighting model. When using the original lighting parameters to perform the lighting rendering task, the power consumption is relatively high and the GPU load is relatively high. Therefore, it is necessary to replace the historical lighting parameters in the copy of the lighting model with the target lighting parameters.

[0201] When binding the copy of the lighting model based on the rendering instruction, before drawing, when the game uses the glBindBuffer instruction to bind the copy of the light source model, that is, by saving the corresponding relationship between the native model and the copy model before, replace the native lighting model ID bound in the rendering instruction with the ID of the copy of the lighting model, so as to use the lighting parameters of the copy of the lighting model for calculation during the rendering process, and then realize the adjustment of the lighting range of each light source in the game scene and reduce the lighting cost.

[0202] Through the above - mentioned scheme, the target lighting parameters can be used to replace the historical lighting parameters in the copy of the lighting model to ensure that the copy of the lighting model uses the latest parameters for rendering. At the same time, bind the copy of the lighting model with the rendering instruction to ensure that the rendering instruction uses the correct lighting model for lighting calculation. Finally, based on the copy of the lighting model and the preset light source, perform the lighting rendering task to achieve the desired lighting effect.

[0203] The other is during the code execution process, performing the rendering task through the shader program, specifically including:

[0204] Convert the target light parameter into a code parameter executable by the shader;

[0205] After adjusting the historical lighting model and historical lighting parameters in the shader using the code parameter, perform the lighting rendering task for the preset light source.

[0206] In practical applications, in addition to handling the replacement of the lighting model and lighting parameters, the lighting effect can also be adjusted in the shader to reduce the lighting cost. After obtaining the target light parameter using the above solution, it is further converted into a code parameter that can be received and executed by the shader. Input this code parameter into the shader,

[0207] For example, inside the Shader shader, the model and Uniform parameters can be adjusted by identifying, modifying, and replacing the source code during the compilation process. This can be achieved by modifying arrays such as model input and Uniform parameter input at the initial position of the main function in the shader code.

[0208] Specifically, in the main function of the shader code, numerical scaling of the product of the attenuation compensation coefficient can be performed on the model input and Uniform parameter input. This means multiplying the original model data and Uniform parameters by the attenuation compensation coefficient to change their values, thereby affecting the lighting effect.

[0209] For example, numerical scaling can be achieved by adding logic similar to the following in the code in the main function:

[0210]

[0211] In the above code, attenuationFactor represents the attenuation compensation coefficient, which can be adjusted as needed. By multiplying the model position and Uniform parameters by the attenuation compensation coefficient, numerical scaling can be performed on them, thereby changing the lighting effect.

[0212] In one or more embodiments of the present application, in response to a scene lighting control request in a virtual scene, determine a lighting control strategy for a preset light source in the virtual scene, including: if a scene lighting control request for reducing the lighting cost triggered by the user is received, or a scene lighting control request for reducing the lighting cost triggered by the preset default is read, then determine whether to select the default configuration according to the local configuration file; if so, determine the lighting control strategy as a fixed control strategy; if not, determine the lighting control strategy as a dynamic control strategy.

[0213] In practical applications, there are various ways to trigger a scene lighting control request. It can be triggered based on the default settings in the configuration file, that is, as long as the game is launched, the request is automatically triggered. It can also be selectively triggered manually by the user according to actual needs. For example, when the user feels that the mobile phone is getting hot, the request can be triggered. Of course, it can also be triggered when certain conditions of the electronic device are detected. For example, when it is detected that the CPU load reaches 80%, the request is triggered; when the temperature of the electronic device reaches 40 degrees Celsius, the request is triggered. It can also be selectively triggered according to the game plot. When the game plot contains a number of light sources greater than a certain threshold, such as greater than 5, the request is triggered; when the game plot is in a close-up state, aiming state or ultimate move confrontation state, the request can also be triggered.

[0214] When selecting a lighting control strategy, it can be selected according to the configuration content in the game's configuration file. For example, in some games, the lighting effect can be configured as a fixed control strategy in the configuration file, and in some games, the lighting effect can be configured as a dynamic control strategy in the configuration file. It should be noted that the configuration file can be modified as needed. For example, the user wants to modify it, or it is modified according to the status of the electronic device.

[0215] In some of the processes described in the above embodiments and the accompanying drawings, multiple operations appear in a specific order. However, it should be clearly understood that these operations can be executed not in the order in which they appear in this article or in parallel. The operation numbers such as 401, 402, etc. are only used to distinguish different operations, and the numbers themselves do not represent any execution order. In addition, these processes can include more or fewer operations, and these operations can be executed in sequence or in parallel. It should be noted that the descriptions such as "first" and "second" in this article are used to distinguish different messages, devices, modules, etc., and do not represent a sequence, nor do they limit that "first" and "second" are of different types.

[0242] The internal functions and structures of the lighting control device are described above, as Figure 9 is a schematic structural diagram of an electronic device provided by an exemplary embodiment of the present application. In practice, the lighting control device may be implemented as an electronic device, including: a memory 91, a processor 92, and a communication component 93.
