Description

Technical Field

[0001] This disclosure relates to the field of intelligent cockpit technology, and more particularly to a method, device, vehicle, medium, and program product for displaying a vehicle model. Background Technology

[0002] In related technologies, with the continuous development of computer graphics technology, the 3D rendering technology in smart cockpits is also constantly improving. In order to enhance the human-computer interaction experience, many vehicles integrate vehicle status visualization functions, including displaying a 3D model of the vehicle on a screen to intuitively present changes in vehicle status such as door opening and closing, window raising and lowering, and sunroof opening. Summary of the Invention

[0003] This disclosure provides a method, apparatus, vehicle, medium, and program product for displaying vehicle models, used to enhance the realism and atmosphere of vehicle status display.

[0004] According to a first aspect of the present disclosure, a method for displaying a vehicle model is provided, comprising: The vehicle's display screen shows a 3D model of the vehicle. In response to receiving the vehicle's headlight control signal, a 3D model with rendered headlight effects is displayed on the screen; wherein, the headlight effects include beam effects corresponding to virtual beams, and different headlight control signals can correspond to different beam effects of the virtual beams.

[0005] In this way, by controlling the headlights with signals, the display can show a 3D model including beam effects, and different headlight signals can correspond to different beam effects, which can significantly enhance the realism and atmosphere of the vehicle status display and improve the user experience.

[0006] In some possible implementations, the headlight control signal includes the headlight type; Different types of vehicle lights correspond to different beam shapes of the virtual beam.

[0007] In this way, different types of car lights correspond to different beam shapes of the virtual beams. When the user operates different car light switches, the screen displays a shape that matches the illumination effect of the car light in the real world, ensuring the realism and accuracy of the rendering effect.

[0008] In some possible implementations, the type of vehicle lights includes low beam headlights and high beam headlights; In response to the vehicle headlight type being a low beam headlight, the beam shape has a first length and a first width; In response to the vehicle headlight type being a high beam headlight, the beam shape is a second length and a second width; Wherein, the second length is greater than the first length, and the second width is less than the first width.

[0009] In this way, by using the different beam patterns of high beams and low beams, the lighting patterns of a vehicle in the real world are simulated, ensuring the realism of the rendering effect. Users can intuitively determine the type of lighting currently on based on the 3D model of the vehicle displayed on the screen, which can improve the user experience.

[0010] In some possible implementations, the headlight effect also includes a volumetric light effect, which is used to simulate the scattering of light in a medium.

[0011] In this way, by rendering volumetric light effects on virtual beams, the scattering phenomenon that occurs when light from a vehicle shines into the air and propagates in a medium can be simulated, significantly enhancing the realism of the vehicle's 3D model rendering and improving the user experience.

[0012] In some possible implementations, the type of vehicle lights includes low beam headlights and high beam headlights; The flow velocity corresponding to the volumetric light effect of the low beam headlight is less than the flow velocity corresponding to the volumetric light effect of the high beam headlight.

[0013] In this way, by using the different flow speeds of volumetric light corresponding to different types of headlights, the flow speed of volumetric light in a real environment can be simulated, significantly enhancing the realism of the vehicle's 3D model rendering and improving the user experience.

[0014] In some possible implementations, before displaying the 3D model with rendered headlight effects on the display screen, the method further includes: Determine the movement speed parameters corresponding to the model texture coordinates of the virtual beam; The headlight effect of the 3D model is rendered using the texture map corresponding to the volumetric lighting effect and the movement speed parameter.

[0015] In this way, by continuously sampling the texture map through the movement speed parameter, the car headlights of the model can have a flowing volumetric light effect, requiring less computational resources and ensuring the real-time performance and smoothness of the rendering.

[0016] In some possible implementations, before displaying the 3D model with rendered headlight effects on the display screen, the method further includes: Determine the camera viewpoint corresponding to the 3D model; Based on the camera viewpoint and the illumination direction corresponding to the virtual beam, the rendering state of the light spot effect and / or halo effect in the vehicle headlight effect is determined, and the rendering state includes a display state or a hidden state. The headlight effects of the 3D model are rendered according to the rendering state.

[0017] In this way, by controlling the rendering state of the halo effect and the light spot effect corresponding to the camera perspective and the illumination direction corresponding to the virtual beam, it is possible to simulate the vehicle state in a real environment where users can observe the halo effect and light spot effect of the headlights, which significantly enhances the realism of the vehicle 3D model rendering and improves the user experience.

[0018] In some possible implementations, the display state of the light spot effect and / or halo effect in the vehicle headlight effect is determined based on the camera viewpoint and the illumination direction corresponding to the virtual beam, including: Determine the angle between the camera viewpoint and the illumination direction corresponding to the virtual beam; In response to the included angle being within a set angle range, the rendering state is determined to be a display state.

[0019] In this way, by determining the angle between the camera viewpoint and the illumination direction corresponding to the virtual beam, the halo effect and / or spot effect are rendered only when the angle is within the set angle range. This can simulate the vehicle state in a real environment where users can observe the halo effect and spot effect of the headlights, significantly enhancing the realism of the vehicle 3D model rendering.

[0020] In some possible implementations, the rendering state of the light spot effect and / or halo effect in the headlight effect is determined based on the camera viewpoint and the illumination direction corresponding to the virtual beam, including: In response to the included angle not being within the set angle range, the rendering state is determined to be a hidden state.

[0021] In this way, by determining the angle between the camera viewpoint and the illumination direction corresponding to the virtual beam, and setting the halo effect and / or spot effect to a hidden state when the angle is not within the set angle range, the realism of the vehicle 3D model rendering is enhanced, while saving some computing resources.

[0022] In some possible implementations, the method further includes: Determine the distance between the camera's viewpoint and the vehicle's 3D model; Based on the distance, adjust the display intensity corresponding to the spot effect and / or the halo effect, wherein the display intensity is negatively correlated with the distance.

[0023] In this way, by dynamically adjusting the display intensity of the light spot and halo effects based on the distance between the camera viewpoint and the 3D model, the visual perception of the light spot and halo effects by users in different positions in a real environment can be simulated, significantly enhancing the realism of the vehicle 3D model rendering and improving the user experience.

[0024] In some possible implementations, the headlight control signal includes headlight type and light status, and the method further includes, before the display screen shows the 3D model with rendered headlight effects: In response to the vehicle headlight type being a set type, the vehicle headlight effect of the 3D model is rendered according to the vehicle headlight type and the light state.

[0025] In this way, by rendering only the lights of a specific type, we can avoid the need for complex state machine management for all lights, thus saving computing resources.

[0026] In some possible implementations, the light state includes an on or off state, and the rendering of the vehicle light effect in the 3D model is performed according to the vehicle light type and the light state, including: Based on the light status, determine the rendering status corresponding to the vehicle light type, whereby the rendering status includes a display status or a hidden status. The headlight effects of the 3D model are rendered according to the headlight type and the rendering state.

[0027] In this way, by determining the rendering state corresponding to the type of vehicle lights based on the lighting status, it can be ensured that the rendering effect of the vehicle lights in the 3D model remains synchronized with the vehicle lights in the real environment. When the user presses any vehicle light switch, the vehicle model on the display screen shows the real-time and accurate effect, enhancing the realism of the vehicle 3D model rendering.

[0028] According to a second aspect of the present disclosure, a display device for a vehicle model is provided, comprising: The first display module is configured to display a three-dimensional model of the vehicle on the vehicle's display screen; The second display module is configured to display a 3D model with rendered headlight effects on the display screen in response to receiving the headlight control signal of the vehicle; wherein the headlight effects include beam effects corresponding to virtual beams, and different headlight control signals can correspond to different beam effects of the virtual beams.

[0029] In some possible implementations, the headlight control signal includes the headlight type; Different types of vehicle lights correspond to different beam shapes of the virtual beam.

[0030] In some possible implementations, the type of vehicle lights includes low beam headlights and high beam headlights; In response to the vehicle headlight type being a low beam headlight, the beam shape has a first length and a first width; In response to the vehicle headlight type being a high beam headlight, the beam shape is a second length and a second width; Wherein, the second length is greater than the first length, and the second width is less than the first width.

[0031] In some possible implementations, the headlight effect also includes a volumetric light effect, which is used to simulate the scattering of light in a medium.

[0032] In some possible implementations, the display device for the vehicle model is further configured to: Determine the camera viewpoint corresponding to the 3D model; Based on the camera viewpoint and the illumination direction corresponding to the virtual beam, the rendering state of the light spot effect and / or halo effect in the vehicle headlight effect is determined, and the rendering state includes a display state or a hidden state. The headlight effects of the 3D model are rendered according to the rendering state.

[0033] In some possible implementations, the display device for the vehicle model is further configured to: Determine the angle between the camera viewpoint and the illumination direction corresponding to the virtual beam; In response to the included angle being within a set angle range, the rendering state is determined to be a display state.

[0034] According to a third aspect of the present disclosure, a vehicle is provided, comprising: processor; Memory used to store processor-executable instructions; The processor is configured to implement the vehicle model display method described in the first aspect of the present disclosure.

[0035] According to a fourth aspect of the present disclosure, a computer-readable storage medium is provided having a computer program stored thereon, which, when executed by a processor, implements the vehicle model display method described in the first aspect of the present disclosure.

[0036] According to a fifth aspect of the present disclosure, a computer program product is provided, including a computer program that, when executed by a processor, implements the vehicle model display method described in the first aspect of the present disclosure.

[0037] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: This disclosure displays a 3D model of the vehicle on a vehicle's display screen; and in response to receiving a vehicle headlight control signal, displays a 3D model with rendered headlight effects on the display screen; wherein the headlight effects include beam effects corresponding to virtual beams, and different headlight control signals can correspond to different beam effects of the virtual beams. Thus, by controlling the display of a 3D model including beam effects through headlight control signals, and with different headlight signals corresponding to different beam effects, the realism and atmosphere of the vehicle status display can be significantly enhanced, improving the user experience.

[0051] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0052] Among related technologies, 3D (Dimensions) environment rendering technology in smart cockpits can make the rendering effect of vehicle 3D models approach that of real scenes. These 3D models include lighting effects, texture mapping, and physical simulations. Furthermore, real-time rendering is possible, meaning it can respond instantly to user actions, providing a more realistic and smooth interactive experience.

[0053] like Figure 1 As shown, headlight rendering can be achieved by setting a self-illuminating sheet 101 on the headlight model to simulate headlights. The self-illuminating sheet 101 is displayed when the headlights are turned on and hidden when the headlights are turned off, meaning that the headlight effect is not rendered.

[0054] Reference Figure 2 , Figure 2 This is a flowchart illustrating a method for displaying a vehicle model according to an exemplary embodiment, such as... Figure 2 As shown, the method for displaying the vehicle model includes the following steps.

[0055] In step S201, a three-dimensional model of the vehicle is displayed on the vehicle's screen.

[0056] In step S202, in response to obtaining the vehicle's headlight control signal, a three-dimensional model with rendered headlight effects is displayed on the screen; wherein, the headlight effects include beam effects corresponding to virtual beams, and different headlight control signals can correspond to different beam effects of the virtual beams.

[0057] For example, the vehicle's display screen could be a central control screen or a digital instrument cluster. The display screen can be used to show a three-dimensional model of the vehicle. This three-dimensional model is a three-dimensional model used to visually demonstrate the vehicle's appearance, structure, or other details.

[0058] For example, a headlight control signal is a command used to control the state of the headlights. Headlight control signals are issued by the user or automatically by the vehicle system.

[0059] For example, the headlight control signal can come from the vehicle's physical buttons. For instance, when a user rotates the headlight button, the headlight control signal is triggered, which can control the headlight type to switch between headlights, fog lights, and parking lights; when a user toggles the lever corresponding to the headlights, the headlight control signal is triggered, which can control the turn signals to switch between left and right turn signals, or control the headlights to switch between high beams and low beams, and so on.

[0060] For example, the headlight control signal can come from a virtual button on the touchscreen. For instance, when a user clicks "Turn on fog lights" on the vehicle's display screen, the headlight control signal is triggered, which can control the fog lights to turn on.

[0061] For example, the headlight control signal can come from the vehicle system. For instance, the vehicle uses a light sensor to identify the ambient brightness. When the ambient brightness is lower than a set threshold, the headlight control signal is triggered, which can control the high beam, low beam, or parking lights to be turned on.

[0062] For example, a virtual light beam is a lighting effect simulated using computer graphics algorithms during the rendering process of a 3D model. A virtual light beam is a graphical image that simulates the illumination range and shape of real light. Unlike the lighting effect achieved by setting the headlight components on a 3D model as self-illuminating sheets, a virtual light beam is a simulated light beam with direction, shape, and volume.

[0063] For example, a beam effect is a specific visual form presented by a virtual beam. This can be achieved by setting various attributes of the virtual beam, such as its color, shape, and flow effects, and then rendering the virtual beam.

[0064] For example, based on the actual vehicle headlight control signals, a near-realistic beam effect of the vehicle headlights can be rendered. For instance, for both low beam and high beam headlights, the width and length of the virtual beam can change according to the low beam or high beam control signals. For example, the width of the virtual beam for signal lights such as parking lights and brake lights is greater than the width of the virtual beam for headlights, but the length of the virtual beam is much shorter than the length of the virtual beam for headlights. For example, the color of signal lights such as parking lights and brake lights might be a warning red, while headlights might be a brighter white light.

[0065] For example, the rendering parameters corresponding to different headlight control signals can be preset according to actual conditions, so that different headlight control signals can correspond to different beam effects of the virtual beam. The headlight control signals can indicate the headlight type and light state. Correspondingly, the rendering parameters can include the relative position of the light model and the headlight model, light color, light shape, light transparency, volumetric lighting effects, rendering state (including display and hidden states), and the corresponding flicker interval if temporal features exist, etc.

[0066] For example, control signals on the vehicle bus can be continuously monitored. When the vehicle's headlight control signal is acquired, the preset rendering parameters corresponding to the headlight control signal can be determined according to the headlight type and light status indicated by the headlight control signal. The three-dimensional model of the vehicle can be rendered using the preset rendering parameters and output to the display screen for display, thereby achieving real-time and dynamic synchronization between the image and the vehicle status.

[0067] In this way, by controlling the headlights with signals, the display can show a 3D model including beam effects, and different headlight signals can correspond to different beam effects, which can significantly enhance the realism and atmosphere of the vehicle status display and improve the user experience.

[0068] In some possible implementations, the headlight control signal includes the headlight type; Different types of vehicle lights correspond to different beam shapes of the virtual beam.

[0069] For example, vehicle light control signals may include parameters such as light type and light status. Light type refers to the different functional or specification categories of lights on the vehicle. For instance, light types may include high beams, low beams, fog lights, turn signals, side marker lights, reversing lights, and brake lights. Different light types have specific lighting or signal indication purposes.

[0070] For example, beam shape refers to the geometry, spatial distribution, and projection pattern of a virtual light beam on the screen. Beam shape is used to define the beam shape corresponding to the lighting effect of vehicle lights in a 3D model. For instance, the beam shape of a high beam can be a narrow, elongated conical beam, while the beam shape of a low beam can be a wide, short, conical beam; the beam shape of fog lights, turn signals, etc., can be a wide, short, diffused light.

[0071] For example, the different beam shapes of virtual beams corresponding to different types of vehicle lights can be predefined in the rendering software, and a mapping relationship can be established. A database or mapping rules can be pre-set to store the mapping relationship. Based on the parsed vehicle light type, the rendering parameters of the corresponding beam shape can be found through the mapping relationship.

[0072] For example, if the headlight type is high beam, the rendering parameters corresponding to the beam shape include: a cone shape, a length of 15 meters, a divergence angle of 10 degrees, and a brightness of height; if the headlight type is low beam, the rendering parameters corresponding to the beam shape include: a cone shape, a length of 8 meters, a divergence angle of 45 degrees, and a brightness of medium.

[0073] For example, after obtaining the vehicle headlight control signal, the headlight type information can be parsed out. Once the headlight type is identified in the headlight control signal, the corresponding rendering parameters can be called according to a preset mapping relationship to render the virtual beam of the headlight type. Based on the queried shape parameters, the graphics rendering engine calls the corresponding shader program and particle effects to render a virtual beam with a specific shape in real time at the headlight source position of the vehicle's 3D model.

[0074] In this way, different types of car lights correspond to different beam shapes of the virtual beams. When the user operates different car light switches, the screen displays a shape that matches the illumination effect of the car light in the real world, ensuring the realism and accuracy of the rendering effect.

[0075] In some possible implementations, the type of vehicle lights includes low beam headlights and high beam headlights; In response to the vehicle headlight type being a low beam headlight, the beam shape has a first length and a first width; In response to the vehicle headlight type being a high beam headlight, the beam shape is a second length and a second width; Wherein, the second length is greater than the first length, and the second width is less than the first width.

[0076] For example, length is the projection distance of the virtual beam rendered on the screen, which can be used to characterize how far the light can reach. The first length refers to the projection distance corresponding to the low beam, and the second length refers to the projection distance corresponding to the high beam.

[0077] For example, the width refers to the coverage area corresponding to the lateral spread of the virtual beam, which can be used to characterize the cross-sectional size of the beam at a specific distance. The first width refers to the spread width corresponding to the low beam beam, and the second width refers to the spread width corresponding to the high beam beam.

[0078] For example, the second length is greater than the first length, which can be used to indicate that the projection distance of the beam pattern corresponding to the high beam is greater than the projection distance of the beam pattern corresponding to the low beam; the second width is less than the first width, which can be used to indicate that the diffusion range of the beam pattern corresponding to the high beam is less than the diffusion range of the beam pattern corresponding to the low beam.

[0079] For example, taking a vehicle body length of 25cm in a 3D model as an example, in the beam pattern corresponding to the low beam headlight, the first length can be 15cm, and at the first length of 10cm, the corresponding first width can be 30cm; in the beam pattern corresponding to the high beam headlight, the second length can be 30cm, and at the first length of 30cm, the corresponding second width can be 10cm.

[0080] In this way, by using the different beam patterns of high beams and low beams, the lighting patterns of a vehicle in the real world are simulated, ensuring the realism of the rendering effect. Users can intuitively determine the type of lighting currently on based on the 3D model of the vehicle displayed on the screen, which can improve the user experience.

[0081] In some possible implementations, the headlight effect also includes a volumetric light effect, which is used to simulate the scattering of light in a medium.

[0082] For example, volumetric lighting is a rendering technique in computer graphics that simulates the scattering of light in a participating medium. For instance, it can simulate the scattering of light as it propagates through air containing media such as fog, dust, rain, and smoke.

[0083] For example, volumetric lighting effects are beams of light that possess a three-dimensional sense of volume, texture, and dynamic change. Rendering techniques for volumetric lighting effects can simulate the interaction between light and the medium through ray stepping algorithms, and optimize the rendering of dynamic beam effects by combining shader programming and the rendering workflow.

[0084] For example, a volumetric region representing the medium can be defined in the rendering engine. This volumetric region contains virtual particles that can be used to represent the concentration and distribution of fog, dust, and rain. The renderer performs dense sampling along the path of each ray in the beam, dividing it into countless tiny steps. At each sampling point, it calculates the light intensity, medium density, and scattering coefficient. The resulting volumetric lighting effect of the entire beam is then composited with the previously rendered 3D vehicle model and scene to ultimately produce a beam of light that appears to realistically penetrate the air and has a sense of volume.

[0085] For example, volumetric lighting effects can also be achieved through texture mapping. The volumetric lighting effect of a conical beam in different density media can be pre-calculated and stored as a dedicated lookup texture map. During real-time rendering, the texture map can be sampled based on a set distance and movement speed to quickly obtain an approximate volumetric lighting effect, avoiding complex real-time step calculations.

[0086] In this way, by rendering volumetric light effects on virtual beams, the scattering phenomenon that occurs when light from a vehicle shines into the air and propagates in a medium can be simulated, significantly enhancing the realism of the vehicle's 3D model rendering and improving the user experience.

[0087] In some possible implementations, the type of vehicle lights includes low beam headlights and high beam headlights; The flow velocity corresponding to the volumetric light effect of the low beam headlight is less than the flow velocity corresponding to the volumetric light effect of the high beam headlight.

[0088] For example, flow velocity is the scrolling speed of a dynamic noise texture map used to modulate volumetric lighting effects, or the rate at which internal particles move. A higher flow velocity means that the dust inside the beam moves faster, making the beam appear more active; a lower flow velocity makes the beam appear calmer.

[0089] For example, in real-world scenarios, high beams have higher power, stronger energy, and a longer reach, causing airborne particles to move more violently. Low beams, on the other hand, have lower power and softer light, thus causing the particles to move more gently.

[0090] For example, a mapping rule library can be preset so that when the headlight type is low beam, the volumetric light flow rate parameter can be set to a set low speed value; when the headlight type is high beam, the volumetric light flow rate parameter can be set to a set high speed value.

[0091] For example, after receiving the flow velocity, the graphics rendering engine can control the offset speed of the 3D noise texture simulating volumetric lighting effects. Setting a high speed corresponds to a faster scrolling noise texture map, with more rapid and obvious dynamic changes within the beam. Setting a low speed corresponds to a slower scrolling noise texture map, with only subtle and gentle dynamic changes within the beam.

[0092] In this way, by using the different flow speeds of volumetric light corresponding to different types of headlights, the flow speed of volumetric light in a real environment can be simulated, significantly enhancing the realism of the vehicle's 3D model rendering and improving the user experience.

[0093] In some possible implementations, before displaying the 3D model with rendered headlight effects on the display screen, the method further includes: Determine the movement speed parameters corresponding to the model texture coordinates of the virtual beam; The headlight effect of the 3D model is rendered using the texture map corresponding to the volumetric lighting effect and the movement speed parameter.

[0094] For example, the model corresponding to the virtual beam in the vehicle's 3D model is used to simulate the effect of the headlight beam, with the low beam and high beam beams approximating cones. For example, Figure 3 The virtual beam shown corresponds to a sub-model, where the shape of the beam sub-model is approximately cone-shaped.

[0095] For example, a texture map is a two-dimensional map used to simulate the non-uniform structure and dynamic changes within volumetric light, such as a noise map, gradient map, or cloud map. Texture maps can be set and adjusted according to design requirements to ensure that the final beam texture meets design specifications. Figure 5 The noise graph shown indicates that areas with high noise levels are brighter and less transparent, while areas with low noise levels are darker and more transparent.

[0096] For example, model texture coordinates, also known as UV coordinates, are a coordinate system that maps points on the surface of a 3D model to points on a 2D texture image. U and V are two axes, and the coordinate axes can range from 0 to 1. Model texture coordinates are used to guide the rendering engine to fill the corresponding positions on the 3D model with the pixels from the texture map.

[0097] For example, the movement speed parameter is a variable used to control the dynamic changes of a texture. The movement speed parameter can be used to characterize the offset of the texture coordinates during each frame of rendering. By increasing the movement speed parameter and controlling the movement of the texture map, the flowing sensation of dust floating inside a beam of light can be simulated.

[0098] For example, different types of vehicle lights correspond to different speed parameter values, which can make the flow speed corresponding to the volumetric light effect of the low beam lamp less than the flow speed corresponding to the volumetric light effect of the high beam lamp.

[0099] For example, by unfolding the sub-model corresponding to the virtual beam, the texture coordinates of the sub-model can be obtained. For instance, by... Figure 3 After unfolding the cone shown, we can obtain... Figure 4 The texture coordinates are shown. When unfolding the texture coordinates, the sector after the cone is unfolded can be stretched and transformed to obtain... Figure 4 The square shown has texture coordinates, and each vertex of the beam sub-model has corresponding texture coordinates.

[0100] For example, based on the current headlight type, a preset mapping table can be consulted to determine the corresponding movement speed parameters. For each pixel on the surface of the beam sub-model, the volumetric lighting effect texture map can be sampled based on the original texture coordinates. Then, based on the movement speed parameters and the current time, the texture coordinates are offset, and the new offset texture coordinates are used to sample the volumetric lighting effect texture map to obtain the color corresponding to that pixel.

[0101] In this way, each pixel on the texture coordinate has a corresponding pixel, which together form a volumetric light with a dynamic and flowing feel. The rendered volumetric light effect is then combined with the model of other parts of the vehicle and displayed on the screen.

[0102] In this way, by continuously sampling the texture map through the movement speed parameter, the car headlights of the model can have a flowing volumetric light effect, requiring less computational resources and ensuring the real-time performance and smoothness of the rendering.

[0103] In some possible implementations, before displaying the 3D model with rendered headlight effects on the display screen, the method further includes: Determine the camera viewpoint corresponding to the 3D model; Based on the camera viewpoint and the illumination direction corresponding to the virtual beam, the rendering state of the light spot effect and / or halo effect in the vehicle headlight effect is determined, and the rendering state includes a display state or a hidden state. The headlight effects of the 3D model are rendered according to the rendering state.

[0104] For example, in computer graphics, a camera, or virtual camera, defines the user's position, orientation, and field of view when observing a 3D scene. The camera's viewpoint refers to the angle and position from which the image presented on the screen is viewed. The illumination direction refers to the principal axis direction of the virtual beam corresponding to the headlights, a direction vector defined in 3D space.

[0105] For example, a halo effect is a visual halo effect caused by the scattering and refraction of light inside the camera lens after the camera's viewpoint is pointed at a strong light source. For example, it is one or more colored halo rings that appear around the light source. A bokeh effect is a light and shadow effect produced when the light is blurred.

[0106] For example, the rendering state can be a control switch used to determine whether the light spot effect or halo effect needs to be calculated and drawn in the current frame. The rendering state includes a display state and a hidden state. The display state indicates that the effect can be rendered in the current frame; the hidden state indicates that the effect does not need to be rendered in the current frame, and thus the rendering of the effect can be skipped to save computing resources.

[0107] For example, in the 3D space corresponding to the vehicle model, a first direction vector pointing from the virtual camera position to the headlight source, and a second direction vector corresponding to the axis of the headlight beam model can be determined, and the angle between the first and second direction vectors can be calculated. Based on the size of the angle, the rendering state of the light spot and halo can be determined.

[0108] In this way, by controlling the rendering state of the halo effect and the light spot effect by the camera perspective and the illumination direction corresponding to the virtual beam, the vehicle state when the user observes the halo effect and light spot effect of the headlights in a real environment can be simulated, which significantly enhances the realism of the vehicle 3D model rendering and can improve the user experience.

[0109] In some possible implementations, the display state of the light spot effect and / or halo effect in the vehicle headlight effect is determined based on the camera viewpoint and the illumination direction corresponding to the virtual beam, including: Determine the angle between the camera viewpoint and the illumination direction corresponding to the virtual beam; In response to the included angle being within a set angle range, the rendering state is determined to be a display state; In response to the included angle not being within the set angle range, the rendering state is determined to be a hidden state.

[0110] For example, the included angle is the angle between the direction vector corresponding to the camera's viewpoint and the main direction vector corresponding to the virtual beam. The set angle range is a preset angle interval used to trigger the rendering state of the light spot effect and / or halo effect to the display state.

[0111] For example, the angle range can be a small range of angles. For instance, the included angle is the absolute value of the angle between the direction vector corresponding to the camera viewpoint and the main direction vector corresponding to the virtual beam. The angle range can be from 0° to 20°, which means that the spot effect and / or halo effect will only be displayed when the camera viewpoint is almost parallel to the beam and directly facing the light source.

[0112] For example, when the angle is small, it indicates that the camera viewpoint is almost directly facing the light source, and the rendering state corresponding to the halo effect and / or light spot effect can be set to the display state. When the angle is large, such as 20-90 degrees, it indicates that the camera viewpoint is observing the light beam from the side of the vehicle model, and the rendering state corresponding to the halo effect and / or light spot effect can be set to the hidden state.

[0113] For example, taking a halo effect as an example, such as Figure 6 As shown, when viewed from the side of the vehicle model, the rendered virtual light beam 601 is a cone-shaped light column. At this time, the rendering state corresponding to the halo effect and / or spot effect 602 is set to hidden. Figure 7 As shown, when viewed from the front of the vehicle model, the rendered virtual beam 602 is a diffused light source. At this time, the rendering state corresponding to the halo effect and / or spot effect 602 is set to the display state.

[0114] In this way, by determining the angle between the camera viewpoint and the illumination direction corresponding to the virtual beam, the halo effect and / or spot effect are rendered only when the angle is within the set angle range. This can simulate the vehicle state in a real environment where users can observe the halo effect and spot effect of the headlights, significantly enhancing the realism of the vehicle 3D model rendering.

[0115] In this way, by determining the angle between the camera viewpoint and the illumination direction corresponding to the virtual beam, and setting the halo effect and / or spot effect to a hidden state when the angle is not within the set angle range, the realism of the vehicle 3D model rendering is enhanced, while saving some computing resources.

[0116] In some possible implementations, the method further includes: Determine the distance between the camera's viewpoint and the vehicle's 3D model; Based on the distance, adjust the display intensity corresponding to the spot effect and / or the halo effect, wherein the display intensity is negatively correlated with the distance.

[0117] For example, the distance between the camera viewpoint and the 3D model is the straight-line spatial distance from the position of the virtual camera viewpoint to a reference point on the vehicle's 3D model. The distance between the camera viewpoint and the 3D model can change in real time as the user zooms, rotates, or drags the model.

[0118] For example, display intensity is used to control the viewing angle effect intensity of spot and halo effects. Display intensity can include parameters such as brightness, transparency, spot size or halo diffusion range, and contrast. Specifically, when the distance between the camera's viewing angle and the 3D model increases, the display intensity corresponding to the spot and / or halo effects decreases; conversely, when the distance between the camera's viewing angle and the 3D model decreases, the display intensity corresponding to the spot and / or halo effects increases.

[0119] For example, a pre-defined correspondence between distance and display intensity can be established. This could be achieved by setting a mapping table where different distances and display intensities correspond to each other. The correspondence can be set separately for different parameters within the distance and display intensity settings.

[0120] For example, a mapping function between distance and display intensity can be preset to calculate the display intensity value corresponding to the spot effect and / or halo effect at the current distance. The mapping function can be a linear decay function or a non-linear decay function.

[0121] For example, based on a preset mapping relationship, the corresponding display intensity value at the current distance can be determined, and the calculated display intensity value is passed to the shader program of the spot effect and halo effect to modulate the visual parameters corresponding to the spot effect and halo effect. The rendering engine uses the adjusted parameters to draw the effect.

[0122] In this way, by dynamically adjusting the display intensity of the light spot and halo effects based on the distance between the camera viewpoint and the 3D model, the visual perception of the light spot and halo effects by users in different positions in a real environment can be simulated, significantly enhancing the realism of the vehicle 3D model rendering and improving the user experience.

[0123] In some possible implementations, the headlight control signal includes headlight type and light status, and the method further includes, before the display screen shows the 3D model with rendered headlight effects: In response to the vehicle headlight type being a set type, the vehicle headlight effect of the 3D model is rendered according to the vehicle headlight type and the light state.

[0124] For example, the light status is a state variable describing the dynamic behavior of vehicle lights, which can include an on or off state. When the vehicle light type is a turn signal or hazard warning flasher, the light status can also have dynamic characteristics such as a flashing state.

[0125] For example, the setting type is a preset vehicle headlight type that can be rendered. The setting type can include low beam headlights, high beam headlights, turn signals, fog lights, hazard warning lights, etc. Renderable vehicle headlight types can be predefined, and rendering parameters can be preset for the setting type of headlight. When it is determined that the headlight type includes the setting type, the headlight effect corresponding to the headlight model in the 3D model can be rendered based on the headlight type and light state.

[0126] In some implementations, the flashing states of turn signals and hazard warning lights may require significant computational resources. Therefore, low beam and high beam lights can be set as preset types. When a vehicle control signal is received, if the headlight type is determined to be low beam or high beam, the corresponding headlight effect in the 3D headlight model can be rendered based on the headlight type and specific lighting state. If the headlight type is determined to be turn signal or hazard warning light, rendering is not required.

[0127] In this way, by rendering only the lights of a specific type, we can avoid the need for complex state machine management for all lights, thus saving computing resources.

[0128] In some possible implementations, the light state includes an on or off state, and the rendering of the vehicle light effect in the 3D model is performed according to the vehicle light type and the light state, including: Based on the light status, determine the rendering status corresponding to the vehicle light type, whereby the rendering status includes a display status or a hidden status. The headlight effects of the 3D model are rendered according to the headlight type and the rendering state.

[0129] For example, the light status is determined based on control operations on the physical state of the light, such as a user's toggle operation on a physical switch, a click operation on a virtual switch, or an automatic signal light based on vehicle sensors. Here, an "on" state indicates that the user or system intends to activate that type of light; a "off" state indicates that the user or system intends to deactivate the light.

[0130] For example, the rendering state corresponding to the type of vehicle headlight can be determined based on the headlight status. When the headlight status is high beam or low beam on, the rendering state of the virtual beam corresponding to the high beam or low beam can be determined to be the display state; when the headlight status is high beam or low beam off, the rendering state of the virtual beam corresponding to the high beam or low beam can be determined to be the hidden state.

[0131] For example, the rendering state corresponding to the vehicle headlight type can be determined based on the headlight status. The headlight type and rendering state are then input into the rendering engine, which can perform operations based on the input rendering state.

[0132] For example, if the rendering state is displayed, the rendering engine will look up all the rendering parameters corresponding to the headlight type, such as halo intensity, beam color, and flow speed, and call the corresponding shader program to perform a complete visual rendering of the headlight model. If the rendering state is hidden, the rendering engine can skip the rendering calculation for the headlight type, and the headlight effect will not be visible in the final display screen.

[0133] For example, the rendering state corresponding to the type of vehicle headlight can be determined based on the lighting status, and an independent rendering switch can be provided for each type of headlight. Users can precisely render or hide the corresponding headlight effects by turning on or off low beams, high beams, fog lights, etc., without affecting each other at all.

[0134] In this way, by determining the rendering state corresponding to the type of vehicle lights based on the lighting status, it can be ensured that the rendering effect of the vehicle lights in the 3D model remains synchronized with the vehicle lights in the real environment. When the user presses any vehicle light switch, the vehicle model on the display screen shows the real-time and accurate effect, enhancing the realism of the vehicle 3D model rendering.

[0135] In a specific example, refer to Figure 8 Taking low beam and high beam headlights as examples, a flowchart illustrating a method for displaying a vehicle model is shown. The display method can be implemented using a vehicle rendering system, which includes a headlight control signal monitoring module, a low beam rendering module, a hiding module, and a high beam rendering module. Both the low beam and high beam rendering modules can include a beam rendering module and a halo / spot rendering module.

[0136] For example, the headlight control signal monitoring module is used to monitor vehicle signals. For instance, when the vehicle turns on the low beam headlights, the monitoring module can receive the signal that the low beam headlights are on; when the vehicle turns off the low beam headlights, the monitoring module can receive the signal that the low beam headlights are off. The same applies to the high beam headlight signal.

[0137] For example, when the headlight control signal monitoring module receives a headlight control signal, it can determine the headlight type and light status, where the light status includes on and off states. For instance, processing continues only if the headlight control signal is determined to be at least one of the following: low beam on signal, low beam off signal, high beam on signal, and high beam off signal; otherwise, no processing is performed.

[0138] For example, the beam rendering module is used to simulate the area illuminated by the vehicle's high beams and low beams. The thickness and length of the beam change according to whether it's a low beam or high beam signal. For instance, when the low beams are on, the beam becomes thicker and shorter, simulating the short illumination range of low beams; when the high beams are on, the beam becomes thinner and longer, simulating the long illumination range of high beams. The beam also includes volumetric lighting effects to simulate the scattering phenomenon that occurs when light from vehicle headlights propagates through a medium in the air.

[0139] For example, when the headlight control signal indicates that the low beam is on, the illumination range is short, the beam is relatively thick, the brightness is low, and the beam is relatively dispersed, resulting in a weaker simulation of volumetric light scattering from the atmosphere. When the headlight control signal indicates that the high beam is on, the illumination range is long, the beam is relatively thin, the brightness is high, and the beam is relatively concentrated, resulting in a stronger simulation of volumetric flow scattering from the atmosphere. When the headlight control signal indicates that either the low beam or high beam is off, both the beam effect and the light spot effect are hidden.

[0140] For example, the halo / spot rendering module can be used to simulate the spot and halo effects when vehicle headlights shine directly into a person's eye. When the headlight control signal indicates that the low beam or high beam is turned on, it can determine in real time whether the angle between the camera's viewpoint and the illumination direction corresponding to the virtual beam conforms to a preset angle range. This angle can be calculated by multiplying the direction vector corresponding to the camera's viewpoint with the direction vector corresponding to the axis of the virtual beam. If the angle conforms to the preset angle range, spot and / or halo effects can be rendered on the virtual beam. If the angle does not conform to the preset angle range, spot and / or halo effects on the virtual beam can be hidden.

[0141] like Figure 6-7 The image shows a 3D model with rendered headlights. Figure 6 The area corresponding to the lines in front of the vehicle represents the beam effect of virtual beam 601; the actual beam shape is... Figure 3 The cone shape shown. (As shown in the image) Figure 7As shown, when viewed from the front of the vehicle model, the rendered virtual beam 601 is a scattering cone beam, and the area corresponding to the scattering lines has a ring-shaped halo effect and / or a spot effect 602.

[0142] The vehicle's display screen can also show multiple controls, including a time control and a status control. The time control displays the current time of the vehicle's infotainment system; the status control can be used to control or display the open or closed status of the doors, hood, trunk, and windows, allowing users to more intuitively observe the vehicle's current status.

[0143] Thus, through the vehicle headlight rendering scheme disclosed herein, there are beams of volumetric light when the headlights are turned on, and there are light spot effects and / or halo effects when approaching the headlights. Moreover, the display intensity of the light spot effect and / or halo effect can be correlated with the low beam and high beam signals, enhancing the realism and atmosphere of the scene.
