[0042] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0043] Example

[0044] Figure 1 FIG. 1 is a flow chart of a rendering method provided by an embodiment of the present invention. Figure 1 As shown, the rendering method includes:

[0045] Step 101: Acquire material data of a target scene; the target scene contains multiple objects, and any object is composed of at least one material.

[0046] Specifically, for any material, its material data may include at least one of color data, transparency data, highlight data, roughness data, normal data, scattering data and refraction data.

[0047] Step 102: Analyze the material data, identify and separate the texture of each material, and the texture includes a detail layer and an attribute layer.

[0048] Specifically, the present invention provides a material decomposition and reconstruction engine, which is used to analyze material data, identify and separate the texture of each material, and the texture includes a detail layer and an attribute layer. The detail layer is responsible for describing the microstructure of the material, such as roughness and scratches, etc.; the attribute layer defines the optical properties of the material, such as diffuse reflectivity and specular reflectivity, etc.

[0049] By separating the detail layer and attribute layer of each material, the various properties of the material and its performance under different ambient lighting conditions can be more accurately depicted and controlled to achieve improved rendering realism. At the same time, the separated detail layer and attribute layer can be reused in different rendering environments, without the need to redesign the material for each environment, thus improving rendering efficiency.

[0050] Here, the specific implementation method is: using preset image processing software and rendering algorithms, analyzing material data, identifying and separating the texture of each material, and the texture includes a detail layer and an attribute layer.

[0051] Next, the textures can be optimized to make the transition between them natural and consistent with the visual effects of the original image of the target scene. Specifically, machine learning technology is used to optimize the processing of each layer, for example, the roughness and reflectivity of each layer are optimized to make them consistent with actual physical laws and visual perception. In this way, the transition between the textures is natural and consistent with the visual effects of the original image of the target scene, thereby ensuring the quality and realism in the decomposition and reconstruction process.

[0052] Step 103: For the target area of ​​the target scene, according to the illumination data of the target area, the resolution and level of detail (LOD) of the texture of the target area are adjusted.

[0053] In order to solve the problem of distortion of traditional static maps (pre-rendered or captured images) under complex lighting conditions, the present invention introduces a multi-level texture dynamic adjustment strategy, that is, dynamically adjusting the resolution and detail level of the material map according to the lighting conditions in the target area.

[0054] Specifically, the target scene may be a virtual reality game scene, and the corresponding target area is the area where any player in the virtual reality game scene is located. The target scene may also be other scenes, which are not specifically limited in the present invention. For example, the target scene may also be a scene in a movie.

[0055] Resolution refers to the number of pixels in a texture. High-resolution textures can provide more detailed and realistic visual effects, but they will also increase the rendering burden and memory consumption. Levels of detail can be expressed as texture versions with different resolutions or different levels of detail. For example, a distant mountain may only need a low-resolution texture to maintain its basic appearance, while nearby buildings require higher-resolution textures to show their details. By automatically adjusting the level of detail of the texture, you can effectively reduce the rendering burden and memory consumption while ensuring the visual effect.

[0056] In the embodiment of the present invention, adjusting the resolution and detail level of the map of the target area according to the illumination data of the target area may specifically include:

[0057] (1) Obtain the lighting data of the target area through the light detector.

[0058] Specifically, the light detector can be used to monitor and analyze the lighting conditions in the current scene in real time, including light intensity, light direction, number of light sources, and shadow complexity. The light detector will generate a feedback signal (i.e., the lighting data of the target area) based on the lighting condition information.

[0059] (2) Determine the complexity of target lighting conditions in the target area based on the lighting data.

[0060] Specifically, the complexity of lighting conditions can be divided into a first lighting condition complexity and a second lighting condition complexity. The first lighting condition complexity is less than the second lighting condition complexity. That is, when the target lighting condition complexity is the first lighting condition complexity, it indicates that the target area is an area with simple lighting. When the target lighting condition complexity is the second lighting condition complexity, it indicates that the target area is an area with relatively complex lighting.

[0061] In actual application, if there are multiple light sources in an area, each light source may produce light at different angles and different intensities, which may cause complex light and shadow effects. In this case, this area can be considered as an "area with more complex lighting." Also, if there are multiple objects that block each other in an area, complex shadow effects may occur. In this case, this area can be considered as an "area with more complex lighting." Also, if the light intensity or direction in an area changes frequently, such as lighting conditions in a dynamic environment, this area can be considered as an "area with more complex lighting." Also, if there are a large number of materials with high reflectivity or high refractive index (such as metal, water surface, etc.) in the area, they may produce complex reflection and refraction effects. In this case, this area can be considered as an "area with more complex lighting."

[0062] Based on this, according to the illumination data, the specific implementation method of determining the target illumination condition complexity of the target area can be: if the illumination data shows that the number of light sources in the target area is greater than the preset light source number threshold, or the illumination data shows that there are more than a preset number of mutually occluding objects in the target area, or the illumination data shows that the frequency of change of the light intensity in the target area is greater than the first frequency threshold, or the illumination data shows that the frequency of change of the light direction in the target area is greater than the second frequency threshold, or the illumination data shows that the number of reflected lights in the target area is greater than the preset reflected light number threshold, or the illumination data shows that the number of refracted lights in the target area is greater than the preset refracted light number threshold, then the target illumination condition complexity of the target area is determined to be the second illumination condition complexity. Conversely, if the illumination data shows that the target area does not meet all of the aforementioned conditions, then the target illumination condition complexity of the target area is determined to be the first illumination condition complexity.

[0063] (3) The resolution of the map of the target area is adjusted to the target resolution corresponding to the complexity of the target lighting conditions, and the detail level of the map of the target area is adjusted to the target detail level corresponding to the complexity of the target lighting conditions, wherein the higher the complexity of the lighting conditions, the higher the corresponding resolution and detail level.

[0064] Specifically, following the above example, it is assumed that the complexity of the lighting conditions is divided into the first lighting condition complexity and the second lighting condition complexity, and the first lighting condition complexity is less than the second lighting condition complexity. When the target lighting condition complexity of the target area is the first lighting condition complexity, it indicates that the target area is an area with simple lighting. At this time, the resolution and detail level of the target area map can be at a lower level to optimize the rendering performance. When the target lighting condition complexity of the target area is the second lighting condition complexity, it indicates that the target area is an area with relatively complex lighting. At this time, the resolution and detail level of the target area map can be at a higher level to more accurately reflect the complex lighting effects. In this way, the present invention can effectively reduce the rendering burden and memory consumption while ensuring the visual effect, so that the present invention can take into account both the rendering efficiency and the authenticity of the rendering results.

[0065] Step 104: Adjust the texture level (Texture Level of Detail, Texture LOD) of the texture of the target area according to the viewing angle and viewing distance corresponding to the target area.

[0066] Specifically, the viewing angle refers to the viewing angle of the camera or the observer, which is used to determine the direction in which the observer is observing the object. The viewing distance refers to the distance from the observer or the camera to the rendered object. For example, if the target scene is a virtual reality game scene, the viewing angle is the perspective from which the player observes the surroundings in the game, and the distance is the distance from the player to the observed environment.

[0067] By adapting to the changing viewing angle and distance, the system can dynamically adjust the texture level of the target area's texture. This is called dynamic adjustment of the texture level, also known as LOD. The specific implementation method is: pre-set the texture level corresponding to different combinations of viewing angles and viewing distances, so that when the object is far away from the observer, the details of the object are no longer visually obvious, so the system can lower the texture level and replace it with a simpler texture, thereby saving computing resources. When the object is close to the observer, the system increases the texture level and displays more details for better visual effects. In other words, the farther the viewing distance, the lower the texture level. Similarly, when the viewing angle changes, the system can also make corresponding texture level adjustments to areas with high or low visibility.

[0068] Subsequently, after obtaining the viewing angle and viewing distance corresponding to the target area, the texture level corresponding to the viewing angle and viewing distance combination is determined as the target texture level, and then the texture level of the texture of the target area is adjusted to the target texture level, so as to maintain the best visual effect and performance balance.

[0069] Step 105: Based on a preset rendering algorithm, actually render the target scene to obtain a visual rendering image.

[0070] Specifically, the preset rendering algorithm may be a global illumination and shadow mixed rendering algorithm.

[0071] In order to further improve the overall lighting effect authenticity of the rendered scene, the present invention integrates a global illumination and shadow hybrid rendering algorithm, which not only considers direct illumination, but also calculates indirect illumination and shadow effects. By applying this algorithm at the material level, the lighting interaction between different materials can be made more natural, enhancing the depth and three-dimensionality of the entire scene.

[0072] The specific implementation method is: use ray tracing technology or similar rendering technology to calculate the global illumination effect in the target scene. Then, combine shadow mapping technology to add soft shadow effects between objects to obtain a visual rendering image. In this way, different materials can present highly realistic interactive effects in complex lighting environments.

[0073] Step 106: Outputting a visual rendering image.

[0074] In addition, the present invention also proposes a real-time environment mapping absorption technology, which can generate environment mapping on the surface of the material. These mappings are not pre-set, but dynamically generated according to the camera perspective and the actual environment in the scene. This allows the material surface to truly reflect the surrounding environment, greatly improving the realism of materials such as metal and water surface.

[0075] Based on this, in an embodiment of the present invention, before actually rendering the target scene based on a preset rendering algorithm to obtain a visual rendered image, the rendering method of the present invention may further include:

[0076] (1) Capture the environment image of the target area and convert it into a format suitable for material mapping.

[0077] Specifically, a panoramic camera technology may be used to capture an environment image of a target area, and the environment image may be converted into a format suitable for material mapping.

[0078] (2) Using the environment image, update the environment mapping on the target material of the target area according to the viewing angle corresponding to the target area.

[0079] It should be noted that when the environment image is used to update the environment mapping on the target material of the target area according to the viewing angle corresponding to the target area, the mapping algorithm can be optimized to ensure efficient operation even on performance-constrained devices. For example, the texture of the environment image is compressed, so that the memory requirements can be effectively reduced and the performance can be improved. The compression algorithm needs to balance the trade-off between compression rate and image quality. In addition, advanced image filtering algorithms can be reasonably used, including a variety of anti-aliasing techniques, so that the jagged effect of texture mapping can be effectively reduced and the image quality can be improved. In addition, the texture reading mechanism can be optimized, such as using pre-fetching technology (pre-fetching) and caching technology (caching), so that the reading of system memory during mapping can be reduced, thereby improving performance.

[0080] The following example illustrates a practical application scenario of the present invention.

[0081] Assume that the target scene is a room in a virtual reality game scene, which contains a variety of materials (glass, metal, cloth, etc.). Using the rendering method of the present invention, the attribute layer and detail layer of each material are first parsed and optimized. When the player moves in the room, the display details of each material will be adjusted according to the current light conditions and visual needs. When the player approaches the window, the light outside the window will produce highlights on the metal object. At this time, the metal surface will reflect the scene outside the window, enhancing the sense of reality. At the same time, the global illumination and shadow mixing rendering algorithm will ensure that the shadows and lighting of all objects interact naturally, making the entire scene look more realistic.
