Description

Technical Field

[0001] This disclosure relates to the field of image processing, and more specifically, to a method and apparatus for rendering lighting on volumetric components. Background Technology

[0002] Currently, many game developers, in order to depict the effects of virtual objects emitting light and indirect illumination in game scenes, typically place multiple reflective sphere components within the scene to provide reflection information, such as light reflection and indirect illumination. When the user captures light information from the game scene through a virtual camera, the game rendering system can perform a simple weighted mixing calculation on the reflection information provided by each reflective sphere component to achieve lighting rendering for a specific game scene. However, this method is usually limited to the area where the reflective sphere components are located. When the virtual camera is outside the reflective sphere component area—for example, when the reflective sphere component is indoors and the user-controlled game character is outdoors—the lack of occlusion determination can lead to the game rendering system using indoor reflective sphere components to reflect virtual objects outdoors. This results in incorrect rendering parameters, causing the final rendered game scene to differ from the real scene, resulting in poor rendering quality.

[0003] There is currently no effective solution to the above problems. Summary of the Invention

[0004] This disclosure provides at least some embodiments of a lighting rendering method and apparatus for a volumetric component, in order to at least solve the technical problem in the related art that the rendering effect is poor when using multiple light sources to perform lighting rendering on a single volumetric component.

[0005] According to one embodiment of this disclosure, a lighting rendering method for volumetric components is provided, comprising: acquiring multiple volumetric components located within the field of view of a virtual camera in a game scene; determining a target voxel from multiple voxels in the game scene that satisfies the rendering conditions corresponding to the volumetric component; determining a blending weight value of the target voxel based on the priority and attribute parameters of the volumetric components, wherein the blending weight values ​​of the other voxels besides the target voxel among the multiple voxels are first preset values; and performing lighting rendering on scene objects in the game scene based on the blending weight values ​​of the multiple voxels.

[0006] According to one embodiment of this disclosure, a lighting rendering apparatus for volumetric components is also provided, comprising: a component acquisition module for acquiring multiple volumetric components located within the field of view of a virtual camera in a game scene; a voxel determination module for determining a target voxel from the multiple voxels in the game scene that satisfies the rendering conditions corresponding to the volumetric component; a weight value determination module for determining a mixed weight value of the target voxel based on the priority and attribute parameters of the volumetric components, wherein the mixed weight value of the other voxels besides the target voxel among the multiple voxels is a first preset value; and a rendering module for performing lighting rendering on scene objects in the game scene based on the mixed weight values ​​of the multiple voxels.

[0007] According to one embodiment of the present disclosure, a computer-readable storage medium is also provided, which stores a computer program, wherein the computer program is configured to execute the lighting rendering method of the volumetric component in any of the preceding claims when running.

[0008] According to one embodiment of this disclosure, an electronic device is also provided, including a memory and a processor, wherein the memory stores a computer program and the processor is configured to run the computer program to perform the lighting rendering method for volumetric components as described above.

[0009] In at least some embodiments of this disclosure, a method is employed to acquire multiple volumetric components located within the field of view of a virtual camera in a game scene; determine a target voxel from multiple voxels in the game scene that satisfies the rendering conditions corresponding to the volumetric components; determine the blending weight value of the target voxel based on the priority and attribute parameters of the volumetric components; and perform lighting rendering on scene objects in the game scene based on the blending weight values ​​of multiple voxels. This method utilizes volumetric components that can be acquired within the field of view of the virtual camera and are located in the same space as the volumetric components to be rendered to render the target voxel, thereby greatly improving the efficiency of lighting rendering. Furthermore, the method determines the blending weight of each volumetric component to the target voxel based on the priority and attribute parameters of the volumetric components, and then uses the blending weight to perform lighting rendering on scene objects, making the final rendered lighting effect more consistent with the real scene. This solves the technical problem in related technologies where the rendering effect is poor when using multiple light sources to light-render a single volumetric component.

[0016] To enable those skilled in the art to better understand the present disclosure, the technical solutions of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present disclosure, and not all embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present disclosure.

[0017] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0018] In one possible implementation, the method of directly utilizing the reflection parameters of each reflective sphere component for lighting rendering in the field of image processing still suffers from poor rendering effects after practical experience and careful research. Therefore, the game scene applied in this disclosure embodiment can be any 3D game scene with lighting effects, and the target game type is generally a 3D role-playing game. A method for lighting rendering of volumetric components is proposed, which involves: acquiring multiple volumetric components within the field of view of a virtual camera in the game scene; determining target voxels that meet the rendering conditions corresponding to the volumetric components from multiple voxels in the game scene; and rendering based on the priority and attributes of the volumetric components. The method determines the blending weights of the target voxels based on the blending weights of multiple voxels. It renders the target voxels using volume components that can be captured within the virtual camera's field of view and are in the same space as the volume component to be rendered, which greatly improves rendering efficiency. Furthermore, it determines the blending weights of each volume component to the target voxel based on the priority and attribute parameters of the volume components, and then uses the blending weights to render the scene objects, making the final rendered lighting effect more consistent with the real scene. This solves the technical problem of poor rendering effect when using multiple light sources to render a single volume component in related technologies.

[0019] The methods and embodiments described above in this disclosure can be executed on mobile terminals, computer terminals, or similar computing devices. Taking a mobile terminal as an example, the mobile terminal can be a smartphone, tablet computer, PDA, mobile internet device, PAD, game console, or other terminal device.

Figure 1 As shown, a mobile terminal may include one or more ( Figure 1 Only one is shown in the diagram. Processor 102 (processor 102 may include, but is not limited to, a central processing unit (CPU), graphics processing unit (GPU), digital signal processing (DSP) chip, microprocessor (MCU), programmable logic device (FPGA), neural network processor (NPU), tensor processor (TPU), artificial intelligence (AI) type processor, etc.) and memory 104 for storing data.

[0021] Those skilled in the art will understand that Figure 1 The structure shown is for illustrative purposes only and does not limit the structure of the mobile terminal described above. For example, the mobile terminal may also include components that are more... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.

[0022] According to one embodiment of this disclosure, an embodiment of a lighting rendering method based on volume components is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0023] In one possible implementation, this disclosure provides a volumetric component-based lighting rendering method that provides a graphical user interface through a terminal device, wherein the terminal device may be the aforementioned local terminal device or a client device in the aforementioned cloud interaction system. Figure 2 This is a flowchart of a volumetric component-based lighting rendering method according to one embodiment of the present disclosure. A graphical user interface is provided through a terminal device, and the content displayed by the graphical user interface includes a touch area, such as... Figure 2 As shown, the method includes the following steps:

[0024] Step S202: Obtain multiple volumetric components within the field of view of the virtual camera in the game scene.

[0025] The aforementioned virtual camera is generally used to simulate the user's field of view. Users can use the virtual camera to capture virtual scenes within the game, such as a study scene with tables, chairs, books, and bookshelves, or a city scene with lawns, buildings, and vehicles. Each volumetric component typically corresponds to a rendering influence space, which can be used to provide reflection information for the game scene, such as light reflection and indirect lighting. Therefore, multiple volumetric components can generally be set in the virtual scene to simulate the indirect light reflection effects between different game objects. Since there may be indirect reflected light illumination between different game objects, the voxels on those objects will be affected by other game objects. Setting a corresponding reflection component for each game object to render the game scene's lighting may result in low rendering efficiency and high rendering pressure. Therefore, to improve the overall lighting rendering efficiency of the game scene, the lighting rendering influence between different game objects can be replaced by the rendering effects of multiple volumetric components. In other words, multiple volumetric components can be set in the game scene to achieve simplified lighting rendering between different game objects.

[0026] In one alternative embodiment, the shape of the volume component can generally be spherical or square. The specific component shape can be set according to actual needs and is not limited here.

[0027] In one optional embodiment, since multiple volume components may overlap, taking the study scene mentioned above as an example, if the study is large, multiple volume components can be set in the study to ensure that the coverage of the volume components can encompass the entire study. This ensures that multiple game objects in the study can be rendered with indirect light reflection effects. For light source areas, such as near a candle, in order to show the difference in brightness between the area around the candle and other areas, as well as the effect of the candle on the lighting of other areas, multiple symmetrical volume components can be set around the candle to simulate the lighting effect. In this case, the area where the candle is located can be the overlapping area of ​​multiple volume components. Generally, since the scene outside the study may also require lighting rendering, a larger volumetric component can be set up to simulate the indirect light reflection effect outside the study. However, this volumetric component outside the study may overlap with multiple volumetric components inside the study. If the volumetric component is directly used to render the voxels in the overlapping area, such as when lighting the table in the study, the volumetric component outside the study might also affect the table's rendering. This differs from the lighting effects in a real-world scene, leading to errors in lighting rendering parameters and resulting in a less realistic rendering. Therefore, to address this issue, before lighting the game objects, multiple volumetric components within the virtual camera's field of view can be acquired. Then, volumetric components with the same spatial information as the game objects can be used for lighting rendering. This ensures that the lighting rendering effect of each game object more closely matches the visual effect that users would experience in a real-world scene.

[0028] Taking the study room scenario above as an example, if the virtual camera is currently inside the study room, the volume components that can be obtained first can include indoor volume components; if the virtual camera is outside the study room, the volume components that can be obtained through the door can include both indoor and outdoor volume components.

[0029] In one optional embodiment, the volume component can also be set as a movable component according to actual needs. For example, when there is a moving light source, the intensity and brightness of the light reflected from the surface of the object will change at different times. Therefore, in order to make the rendered effect more realistic, the volume component can be set as a movable component, and the position parameters or attribute parameters of the volume component can be changed according to the preset lighting rules, thereby improving the realism of the final lighting rendering effect.

[0030] In one optional embodiment, a frustum elimination method or a rasterization elimination method can also be used to determine multiple volume components within the field of view of the virtual camera, so as to ensure the accuracy of the obtained volume components.

[0031] Step S204: Determine the target voxel that meets the rendering conditions corresponding to the volume component from multiple voxels in the game scene.

[0032] The aforementioned target voxel can refer to the volume element on the game object to be rendered in the game scene, obtained through a virtual camera, such as the voxel on the aforementioned table and chair model. Since multiple volume components may overlap and superimpose, the same voxel may be affected by different volume components. Therefore, to improve the rendering accuracy of the game scene, the target voxel can first be determined from multiple voxels in the game scene based on a series of rendering conditions. Then, using the influence weights of multiple volume components on the target voxel, lighting rendering is performed on the game object to be rendered voxel by voxel, thereby improving the overall lighting rendering effect of the game object and ultimately making the rendered game scene more realistic.

[0033] Optionally, determining the target voxel that satisfies the rendering conditions corresponding to the volume component from multiple voxels in the game scene includes: determining a first voxel that is not occluded by scene objects in the game scene from multiple voxels; determining a second voxel located in the volume space of the volume component from the first voxel; and obtaining the target voxel located in the same space as the volume component from the second voxel.

[0034] The first voxel mentioned above can refer to all voxels corresponding to the scene area that can be obtained through the virtual camera; the second voxel mentioned above can refer to the voxel in the space area affected by the volume component in the scene area; the scene object mentioned above can refer to the game object to be rendered, such as the table, chairs, walls, potted plants and other game objects in the aforementioned study scene.

[0035] To improve rendering efficiency, the above rendering conditions may refer to considering only the lighting rendering effect on unoccluded volumetric components within the virtual camera's field of view and in the same space on the game objects to be rendered.

[0036] Figure 3 This is a schematic diagram of a scene where the virtual camera is positioned outside the study according to one embodiment of this disclosure, as shown below. Figure 3As shown, the two rectangles represent wall images, the shape in the larger wall represents the potted plant image, and the shape between the two walls represents a portion of the table and chair images. Taking this virtual scene as an example, if the game objects that can be captured from the current position of the virtual camera include the walls of the study, the table and chair inside the study, and the potted plant outside the study, then for rendering inside the study, we only need to consider the influence of the indoor volume components on the lighting rendering of the table and chair; for rendering outside the study, we only need to consider the influence of the outdoor volume components on the lighting rendering of the walls and potted plant.

[0037] Specifically, the game scene can first be rendered from the front, and based on the scene images captured by the virtual camera, multiple scene areas that are not obscured by scene objects can be identified from the game scene. All voxels corresponding to these scene areas are taken as the first voxel. Continuing with the example of the virtual camera being located outside the study, since the images that can be obtained through the virtual camera include the walls, potted plants, some tables and chairs, as well as other spaces besides these game objects, the first voxel mentioned above can refer to the voxels corresponding to the walls, potted plants, some tables and chairs, and other spaces.

[0038] After determining the first voxel, the spatial information to be rendered can be further determined. For example, if the scene is to be rendered in a study, the volume component can be determined to be an indoor volume component, and the volume space is indoor. After determining the volume space, the game objects in the first voxel scene can be rendered from the back. Based on the volume space of the target volume component, for example, if the volume component is an indoor volume component, the corresponding volume space is indoor, then a second voxel can be determined from the first voxel using a stencil test method, such as the indoor voxel in the first voxel. Continuing with the above... Figure 3 Taking a scene where the virtual camera is located outside the study as an example, if the game object to be rendered is a table, then the second voxel that can be obtained above refers to the voxel on the table and chair models.

[0039] Finally, based on the spatial information of the game object to be rendered and the target volume component mentioned above, the target voxel is determined from the second voxel. For example, if the game object to be rendered is a chair in the aforementioned study scene, and part of the chair is in the indoor space and part is in the outdoor space, then the voxel on the chair model that is indoors can be used as the target voxel. If the game object to be rendered is a table in the aforementioned study scene, and the table model is entirely in the indoor space, then all the voxels on the table model can be used as the target voxel.

[0040] Step S206: Determine the blending weight value of the target voxel based on the priority and attribute parameters of the volume component.

[0041] Among them, the mixed weight value of the voxels other than the target voxel is the first preset value.

[0042] The aforementioned priority can refer to the priority of the influence of multiple volume components on the lighting rendering of the target voxel. In one optional solution of this embodiment, the priority of each volume component can be set according to the center distance between the volume component and the target voxel, or the priority of each volume component can be determined according to the attribute information of the volume component, such as the light intensity. The aforementioned attribute parameters can refer to the blending transition parameters of the volume components to be indoors and outdoors, such as the size of the edge transition area of ​​the volume component and the coefficient of the weight attenuation curve. The aforementioned blending weight value can refer to the influence weight value of other volume components on the lighting rendering of the target voxel after integration. Generally, the blending weight value can be taken as a preset threshold, such as 0.2.

[0043] In one optional embodiment, if a target voxel is affected by multiple volume components, it is necessary to determine the influence weight of each volume component on the target voxel based on the influence priority of the multiple volume components and the mixing transition parameter, thereby determining the aforementioned mixing weight value.

[0044] Optionally, the blending weight values ​​are stored in a preset channel of the target voxel, and the preset channel is stored in an on-chip cache.

[0045] In one alternative embodiment, after determining the blend weight value, the blend weight value can be stored in an on-chip channel of the MRT (Multiple Render Targets). Compared with traditional memory, this channel can be directly read and written, which can greatly improve the efficiency of storing and retrieving the blend weight value.

[0046] Optionally, determining the blending weight value of the target voxel based on the priority and attribute parameters of the volume components includes: determining the target attribute parameters corresponding to the current cycle in multiple iterations from the attribute parameters of the volume components according to the priority of the volume components, wherein multiple iterations correspond one-to-one with multiple volume components; obtaining the first weight value of the target voxel, wherein the first weight value is used to characterize the blending weight value or the first preset value corresponding to the previous cycle; determining the second weight value of the target voxel based on the target attribute parameters; and determining the blending weight value corresponding to the current cycle based on the first weight value and the second weight value.

[0047] When determining the blending weight value corresponding to the target voxel, we can first determine the influence of each volume component on the lighting rendering of the game object to be rendered in an orderly manner according to the preset priority of each volume component, that is, the influence weight of each volume component on the game object to be rendered.

[0048] For example, if the target voxel A to be rendered is simultaneously affected by volume components B, C, and D—that is, if target voxel A is a voxel within the overlapping portion of volume components B, C, and D—then the weight of each volume component's influence on the target voxel can be determined individually based on its priority. If volume component B has the highest attribute parameter, such as maximum light intensity, its priority can be set to a relatively large value of 5. If volume component C has medium light intensity, its priority can be set to a middle value of 3. If volume component D has the lowest light intensity, its priority can be set to a relatively small value of 1. When determining the lighting rendering influence of volume components B, C, and D on target voxel A, the influence weight of each component can be determined repeatedly in the order of B, C, and D, following the aforementioned priority ranking.

[0049] The aforementioned first weight can refer to the mixed weight value that the target voxel has been occupied after each loop, or it can refer to the first preset value corresponding to each volume component during the first loop.

[0050] The aforementioned target attribute parameter can refer to the attribute mixing range corresponding to each volume component in each loop. Continuing with the target voxel A and volume components B, C, and D as examples, the mixing range of volume component B on target voxel A can be determined in the first loop, the mixing range of volume component C on target voxel A can be determined in the second loop, and so on. The mixing range of each volume component is determined in each loop. Using this mixing range, the influence weight of each volume component on target voxel A can be calculated, which is the second weight value mentioned above.

[0051] Optionally, determining the second weight value of the target voxel based on the target attribute parameters includes: determining the second weight value of the target voxel based on the target attribute parameters when the first weight value is less than the second preset value; and stopping the determination of the second weight value of the target voxel based on the target attribute parameters when the second weight value is greater than or equal to the first preset value.

[0052] To ensure that each volume component has an impact on the target voxel as much as possible, thereby improving the final rendering effect of the game scene, and to ensure that the sum of the weights of multiple volume components on the target voxel is no greater than 1, when determining the influence weight of different volume components on the target voxel in each loop, the calculated influence weight can be compared with a second preset value. Only if the first weight is less than the second preset value, the second weight value of the target voxel is determined according to the aforementioned target attribute parameters; if the first weight is greater than or equal to the first preset value, the determination of the second weight value is stopped.

[0053] In one optional embodiment, in order to ensure that the influence of multiple volume components on the target voxel is not unbalanced, the second weight value can be set to 0.5.

[0054] Optionally, determining the mixed weight value corresponding to the current cycle based on the first weight value and the second weight value includes: obtaining the third weight value of the target voxel, wherein the third weight value is used to characterize the remaining weight value or the second preset value corresponding to the previous cycle; obtaining the difference between the third weight value and the first weight value to obtain the weight difference value, wherein the weight difference value is used to characterize the remaining weight value corresponding to the current cycle; determining the weight difference value as the mixed weight value when the weight difference value is less than or equal to the second weight value; and determining the second weight value as the mixed weight value when the weight difference value is greater than the second weight value.

[0055] In one optional scheme of this embodiment, since the maximum weight value that each target voxel can contain is 1, if the sum of the influence weights of multiple volume components on the target voxel is equal to 1, it is no longer necessary to consider the influence of the remaining volume components on the lighting rendering of the target voxel. Therefore, when determining whether the target voxel will be affected by other volume components, the remaining weight value of the target voxel in this loop can be obtained.

[0056] Specifically, we can first obtain the remaining voxel values ​​of the target voxel at the end of the previous loop, and then combine them with the influence weight values ​​already determined during the current loop, i.e., the aforementioned first weight value, to obtain the remaining weight values ​​in the current loop, i.e., the aforementioned weight difference. After determining the weight difference, we can compare this weight difference with the second weight value. If the weight difference is less than or equal to the second weight value, the weight difference can be determined as a mixed weight value; if the weight difference is greater than the second weight value, the second weight value is determined as a mixed weight value.

[0057] After determining the first and second weights mentioned above, the hybrid weights corresponding to the target voxels can be further determined.

[0058] Step S208: Based on the mixed weight values ​​of multiple voxels, perform lighting rendering on scene objects in the game scene.

[0059] The aforementioned scene objects can refer to the game objects to be rendered, such as the table, chairs, walls, and potted plants in the aforementioned study scene. In an optional embodiment, after determining the blending weight value corresponding to the target voxel, the influence it has on the game object to be rendered during lighting rendering can be further determined based on the blending weight value. Through the above process, after determining the blending weight values ​​of each voxel on the corresponding indoor and outdoor scene objects based on different volume components, the scene objects can be rendered with lighting using these blending weights and the attribute parameters corresponding to each voxel.

[0060] In one optional embodiment, after determining the mixing weight values ​​corresponding to the multiple voxels, the direct and indirect light diffusion calculations for the game object to be rendered can be performed according to normal image-based lighting techniques. The calculation results are then optimized and superimposed based on the mixing weight values ​​and rendered onto the game object to be rendered, i.e., the scene object, thereby completing the lighting rendering of the game object to be rendered.

[0061] In one optional embodiment, after calculating the total weight value corresponding to the target voxel, the total weight value can be updated to the corresponding mixed weight value, which facilitates the calculation of mixed weights when rendering other game objects under lighting in the future.

[0062] This application employs a method that acquires multiple volumetric components within the virtual camera's field of view in a game scene; identifies target voxels from multiple voxels in the game scene that meet the rendering conditions corresponding to the volumetric components; determines the blending weight value of the target voxel based on the priority and attribute parameters of the volumetric components; and performs lighting rendering on scene objects in the game scene based on the blending weight values ​​of multiple voxels. This method utilizes volumetric components that can be acquired within the virtual camera's field of view and are in the same space as the volumetric components to be rendered to render the target voxel, greatly improving rendering efficiency. Furthermore, it determines the blending weight of each volumetric component to the target voxel based on the priority and attribute parameters of the volumetric components, and then uses the blending weights to perform lighting rendering on scene objects, making the final rendered lighting effect more consistent with the real scene. This solves the technical problem of poor rendering effect when using multiple light sources to light-render a single volumetric component in related technologies.

[0063] Optionally, determining a first voxel from multiple voxels that is not occluded by scene objects in the game scene includes: performing a depth test on multiple voxels through a first rendering process to obtain a first test result for multiple voxels, wherein the first test result is used to characterize whether the voxel is occluded by scene objects; and determining the first voxel from multiple voxels based on the first test result.

[0064] In one optional embodiment, a first rendering process, such as frontal rendering, can be used to perform preliminary rendering of the game scene. Then, depth testing methods can be used to determine the scene areas that are not occluded by scene objects, such as those described above. Figure 3 The virtual camera is positioned in the scene outside the study. The scene area not obscured by scene objects refers to the area including walls, potted plants, tables, chairs, and other corresponding spaces. After determining the scene area, the voxels within that scene area can be used as the first voxels.

[0065] Optionally, determining the second voxel located in the volume space of the volume component from the first voxel includes: determining the component space corresponding to the volume component; testing the first voxel based on the component space through a second rendering process to obtain a second test result of the first voxel; and determining the second voxel in the first voxel based on the second test result.

[0066] After determining the first voxel, the component space affected by each of the aforementioned volumetric components can be further determined. For example, if there is an indoor volumetric component, then the component space mentioned above refers to the indoor space. After determining the component space, a second rendering process, such as backface rendering, can be used to perform a second rendering of the component space. Finally, using a stencil test method, the second voxel within the virtual camera's field of view can be determined from the first voxel. Since there are spatial regions in the game scene that are not affected by the aforementioned volumetric components, and these spatial regions do not need to consider the influence of lighting rendering, the second voxel mentioned above can refer to the first voxel within the space affected by the corresponding volumetric component obtained after the second rendering process.

[0067] Optionally, obtaining the target voxel located in the same space as the volume component from the second voxel includes: obtaining voxel marking information of the second voxel and component marking information of the volume component, wherein the voxel marking information is used to characterize whether the second voxel is located in a preset space in the game scene, and the component marking information is used to characterize whether the volume component is located in a preset space in the game scene; if the voxel marking information and the component marking information are the same, the second voxel is determined to be the target voxel.

[0068] The aforementioned marking information can generally be used to represent the spatial location of voxels or volume components, such as indoors or outdoors. In an optional embodiment, since only game objects in the same space will have indirect light reflection, for example, only when game objects are all indoors can they influence each other's lighting, and game objects outdoors cannot influence game objects indoors, when determining the target voxel that will affect the lighting rendering of the game object to be rendered, the spatial information of each voxel in the second voxel, i.e., the aforementioned voxel marking information, and the spatial information of each volume component, i.e., the aforementioned component marking information, can be obtained first. Since indoor volume components can only affect indoor second voxels, and outdoor volume components can only affect outdoor second voxels, only when the voxel marking information and component marking information are the same can the voxel be determined to be a voxel that can affect the lighting rendering effect of the game object to be rendered, and the voxel is determined as the target voxel.

[0069] Continuing with the example of the virtual camera being located outside the study, if we want to perform lighting rendering on the indoor scene, we can first obtain the component marker information of the indoor volume component, which is marked as "indoor." Then, we obtain the voxel marker information of the second voxel. If the second voxel is on the potted plant, its marker information is "outdoor"; if the second voxel is on the table, its marker information is "indoor." Since only voxels whose voxel marker information matches the component marker information are affected by the corresponding volume component, only the second voxel on the table can be used as the target voxel in this scene, while the second voxel on the potted plant cannot be used as the target voxel at this time.
