[0016] First, the terms involved in one or more embodiments of this specification are explained.

[0017] Universal Render Pipeline (URP): is a rendering pipeline suitable for multiple hardware platforms, designed to provide high-performance and high-quality graphics rendering. It uses physically based rendering technology, supports dynamic lighting and post-processing effects, and can achieve excellent picture quality while maintaining a high frame rate. URP is designed to provide the best performance for low-end to high-end devices, especially for mobile games or virtual reality applications.

[0018] High Definition Render Pipeline (HDRP): is a rendering pipeline designed for high-end platforms to provide high-fidelity graphics and complex visual effects. It uses physically based lighting and materials, supports high-precision realistic effects, and is widely used in high-quality games, architectural visualization, and automotive simulation. HDRP relies on compute shader technology, has high requirements on the computing power of the device, and usually runs on high-end devices.

[0019] Percentage Closer Filtering (PCF): is a technique used to soften the edges of shadows. It reduces the jaggedness of shadows by sampling the shadow map multiple times and calculating the average depth value, making the shadow edges smoother. PCF technology is widely used in real-time rendering, which can improve the visual effect of shadows while ensuring performance, especially in the case of low-resolution shadow maps.

[0020] Vertex Shader (VS): It is a programmable stage in the graphics rendering pipeline that is responsible for processing vertex data. It is usually used to perform spatial transformation of vertices, lighting calculations, and other vertex-related operations. The output of VS is passed to the subsequent geometry processing stage. It is an indispensable part of the rendering process and can achieve complex vertex deformation and animation effects.

[0021] Pixel Shader (PS): It is a programmable stage in the graphics rendering pipeline for processing pixel colors. It receives data from the rasterization stage and calculates the final color of each pixel based on information such as lighting, materials, and textures. PS plays a key role in achieving complex material effects (such as reflection, refraction, and bump mapping) and is one of the core components of high-quality graphics rendering.

[0022] Compute Shader (CS): A general-purpose computing unit that can perform parallel computing tasks outside the graphics rendering pipeline. It is not limited to graphics processing and can be used for tasks such as physical simulation, image processing, and data compression. The advantage of CS lies in its flexibility and efficiency, and its ability to fully utilize the parallel computing capabilities of modern hardware, but some platforms have limited support for it and may need to be optimized to adapt to different devices.

[0023] Shader Storage Buffer Object (SSBO): A storage buffer object used to store large amounts of data in the graphics pipeline for shader programs to read and write. It can provide a large storage space, facilitate the processing of complex data structures and the interaction of large amounts of data, and is suitable for scenarios that require frequent updates and access to data, providing flexible data storage support for graphics rendering and computing tasks.

[0024] Uniform Buffer Object (UBO): is a buffer object used to store uniform variables in shader programs. It allows multiple uniform variables to be grouped together and efficiently transmitted and updated through buffers. UBO is often used to store data such as matrices and vectors in graphics rendering. It can reduce the repeated definition and update overhead of variables in shader programs, improve rendering efficiency, and is suitable for storing relatively stable uniform variable data that needs to be updated in batches.

[0025] In this specification, a virtual scene rendering method is provided. This specification also relates to a virtual scene rendering device, a computing device, a computer-readable storage medium, and a computer program product, which are described in detail one by one in the following embodiments.

[0026] Normally, virtual scene projects are based on URP (Universal Render Pipeline), but due to the increasing demand for improved graphics on the PC side, HDRP (High Definition Render Pipeline) was added as the PC side pipeline. The reason for choosing to proceed at the same time is that HDRP does not natively support mobile platforms at present.

[0027] See also Figure 1 , Figure 1 A flowchart of a virtual scene rendering method provided according to an embodiment of the present specification is shown, which specifically includes the following steps.

[0028] Step 102: Obtain the scene information to be rendered and the scene rendering configuration information corresponding to the target device.

[0029] In actual applications, the scene information to be rendered is the scene data that needs to be rendered; the target device is the device on which the rendering result will be displayed; and the scene rendering configuration information is the rendering parameters and process set according to the characteristics of the target device.

[0030] The scene information to be rendered can be understood as a collection of data such as all objects, light sources, materials, etc. that need to be rendered during the graphics rendering process. This information usually includes the geometric shapes, textures, lighting conditions, etc. in the scene. For example, in a virtual reality application, the scene information to be rendered may include all objects and their properties in the user's virtual environment, such as the color of the walls, the texture of the floor, the brightness and color of the lights, etc. These data are the basis for the rendering engine to generate the final image.

[0031] The target device can be understood as the device where the rendering results are finally displayed. Its hardware performance and display characteristics will affect the specific configuration of the rendering process. Different devices, such as game consoles, mobile terminals, etc., have different computing capabilities, memory sizes, and display resolutions. For example, on mobile terminals, due to limited hardware resources, the rendering configuration may need to simplify the shadow algorithm or reduce the texture resolution to ensure a smooth user experience. On the computer side, more complex lighting effects and post-processing techniques can be enabled to provide higher quality images.

[0032] Scene rendering configuration information can be understood as specific rendering parameters and processes set according to the characteristics and performance requirements of the target device. These configuration information determines how the rendering engine processes the scene information to be rendered to generate the final image. Scene rendering configuration information may include the implementation method of the lighting process, the generation method of the buffer table, the sampling method of the reflection probe, the selection of the shadow filtering algorithm, and the switch of the post-processing effect. These configuration information needs to be optimized according to the hardware capabilities of the target device to ensure a balance between rendering effect and performance.

[0033] Furthermore, the scene information to be rendered and the scene rendering configuration information corresponding to the target device are obtained, including: Obtaining a target device type corresponding to the target device; Based on the target device type, scene rendering configuration information corresponding to the target device is determined.

[0034] In actual applications, the target device type is the device category corresponding to the scene information to be rendered; the target device type can be understood as the specific device category targeted when rendering the scene. These device categories may include first-class devices, second-class devices, and so on. Each device type has its own unique hardware characteristics and performance limitations, which directly affect the way and effect of scene rendering. For example, first-class devices usually have lower performance, while second-class devices have higher performance. Therefore, understanding the target device type is a key step in determining how to efficiently render the scene.

[0035] The scene rendering configuration information can be understood as a series of rendering parameters and settings determined by the target device type. These configuration information include resolution, frame rate, texture quality, lighting effects, etc. Different device types require different rendering configurations to ensure that the scene can be presented in the best state on different devices.

[0036] Further, based on the target device type, determining the scene rendering configuration information corresponding to the target device includes: In the case where the target device type is a first type device, determining that the scene rendering configuration information corresponding to the target device is performance scene rendering configuration information, wherein the first type device is a device whose device performance is less than a preset threshold; In the case that the target device type is a second-category device, it is determined that the scene rendering configuration information corresponding to the target device is quality scene rendering configuration information, wherein the second-category device is a device whose device performance is greater than or equal to a preset threshold.

[0037] In actual applications, the first category of devices is a device whose performance is less than a preset threshold; the second category of devices is a device whose performance is greater than or equal to the preset threshold; the performance scene rendering configuration information is a rendering setting optimized for the first category of devices; the quality scene rendering configuration information is a rendering setting optimized for the second category of devices; the preset threshold is a standard value used to distinguish device performance.

[0038] The first type of device can be understood as a device whose performance is lower than the preset threshold in the rendering scene. This type of device usually includes some mobile terminals or low-configuration computer devices. In order to achieve smooth rendering effects on these devices, performance scene rendering configuration information is usually adopted. For example, on the mobile terminal, the details of the shadows may be reduced, the resolution of the texture may be reduced, or some high-cost post-processing effects may be turned off to ensure stable rendering performance.

[0039] The second type of device can be understood as a device whose performance is higher than or equal to the preset threshold in the rendering scene. This type of device usually includes a computer or a game console. For these devices, quality scene rendering configuration information can be used to give full play to the performance advantages of the device. For example, on the computer, high-precision shadows, high-resolution textures, and complex lighting effects may be enabled to provide a higher quality visual experience.

[0040] Performance scene rendering configuration information can be understood as a collection of rendering settings optimized for the first type of devices. These settings are designed to reduce the computing burden of the device by simplifying or adjusting the rendering process, thereby achieving smooth rendering effects on performance-constrained devices.

[0041] The quality scene rendering configuration information can be understood as a collection of rendering settings optimized for the second type of devices. These settings are designed to fully utilize the computing power of high-performance devices to provide higher quality visual performance. For example, on the computer side, complex shadow filtering algorithms, high-precision ambient occlusion, and dynamic global illumination effects may be enabled to achieve more realistic rendering effects.

[0042] The preset threshold can be understood as a standard value used to distinguish device performance. This value is usually determined based on the device's hardware parameters (such as processor performance, memory capacity, etc.) or actual rendering performance test results. By using the preset threshold, devices can be effectively divided into first-class devices and second-class devices, thereby allocating appropriate scene rendering configuration information to devices with different performance. For example, the preset threshold can be set based on the device's frame rate performance or rendering load capacity to ensure the rationality and adaptability of the rendering configuration.

[0043] Through the above method, adaptive rendering configuration can be provided for devices with different performance, while ensuring performance and improving rendering quality as much as possible.

[0044] Step 104: Generate virtual scene rendering reference information based on the scene rendering configuration information and the scene information to be rendered.

[0045] In practical applications, virtual scene rendering reference information is rendering guidance data generated based on the scene rendering configuration information of the target device and the information of the scene to be rendered; virtual scene rendering reference information can be understood as a kind of guiding data generated according to the hardware characteristics and rendering requirements of the target device. It combines the original information of the scene to be rendered and the rendering configuration of the target device to optimize the rendering process and effect. For example, on the mobile terminal, the virtual scene rendering reference information may adjust the lighting process from a complex calculation method to an implementation method more suitable for the mobile terminal to adapt to the performance limitations of the mobile terminal. At the same time, it may also simplify the shadow filtering algorithm or turn off some post-processing effects to strike a balance between performance and visual effects.

[0046] Further, the scene rendering configuration information includes performance scene rendering configuration information; Based on the scene rendering configuration information and the scene information to be rendered, generating virtual scene rendering reference information includes: Parsing the performance scene rendering configuration information, obtaining light and shadow rendering configuration sub-information and surface material configuration sub-information; Generate virtual scene light and shadow rendering information based on the scene information to be rendered and the light and shadow rendering configuration sub-information; Generate virtual scene object material rendering information according to the scene information to be rendered and the surface material configuration sub-information; Based on the virtual scene light and shadow rendering information and the virtual scene object material rendering information, virtual scene rendering reference information is generated.

[0047] In actual applications, the light and shadow rendering configuration sub-information is a set of parameters used to define the lighting effects in the virtual scene; the surface material configuration sub-information is a set of parameters used to define the surface material of objects in the virtual scene; the virtual scene light and shadow rendering information is the scene lighting rendering data generated based on the light and shadow rendering configuration sub-information; the virtual scene object material rendering information is the object material rendering data generated based on the surface material configuration sub-information.

[0048] The lighting and shadow rendering configuration sub-information can be understood as a set of parameters used to define the lighting effects in the virtual scene. These parameters include lighting type (such as parallel light, point light, spotlight), lighting intensity, shadow algorithm, reflection probe configuration, etc. For example, on mobile devices, the lighting and shadow rendering configuration sub-information may use a simplified shadow algorithm, such as PCF (Percentage Closer Filtering) shadow filtering; and a lightweight reflection probe sampling method to reduce the computational load and improve rendering performance. On high-performance devices, more complex lighting effects (such as dynamic global illumination or high-precision shadow mapping) may be enabled.

[0049] The surface material configuration sub-information can be understood as a set of parameters used to define the surface material of objects in the virtual scene. These parameters include base color, normal information, metalness, roughness, etc. For example, on mobile devices, the surface material configuration sub-information may optimize the way buffer tables are generated, reduce the number of buffer tables, and reduce memory usage by compressing normal information and metalness data. On high-performance devices, higher-precision material parameters and more complex material models may be used to achieve more realistic surface effects.

[0050] Virtual scene lighting and shadow rendering information can be understood as scene lighting rendering data generated based on lighting and shadow rendering configuration sub-information. These data include lighting calculation results, shadow maps, reflection probe data, etc. For example, on mobile devices, virtual scene lighting and shadow rendering information may use a simplified lighting process, such as using VS (Vertex Shader) and PS (Pixel Shader) instead of CS (Compute Shader) to achieve lighting rendering, so as to reduce the computing burden of the target device. On high-performance devices, more complex lighting data (such as dynamic shadows and high-quality reflection effects) may be generated to provide a more realistic visual experience.

[0051] Virtual scene object material rendering information can be understood as object material rendering data generated based on the surface material configuration sub-information. These data include material property calculation results (such as base color, normal, metalness, etc.) and the interaction between material and lighting. For example, on mobile devices, virtual scene object material rendering information may optimize the storage and access methods of material data to improve cache hit rate and reading performance. On high-performance devices, more complex material rendering data (such as high-precision normal maps and complex lighting reflection models) may be generated to achieve higher quality material performance.

[0052] In the above manner, the light and shadow rendering configuration sub-information and the surface material configuration sub-information together constitute the core part of the scene rendering configuration information. Based on these configuration information, virtual scene light and shadow rendering information and virtual scene object material rendering information that are adapted to the performance of different devices can be generated, thereby achieving a balance between performance and quality.

[0053] Furthermore, based on the scene information to be rendered and the light and shadow rendering configuration sub-information, virtual scene light and shadow rendering information is generated, including: Determining target light and shadow rendering rule information corresponding to the target device based on the light and shadow rendering configuration sub-information; Generate target shadow rendering information according to the to-be-rendered scene information and the light and shadow rendering configuration sub-information; Based on the target light and shadow rendering rule information and the target shadow rendering information, virtual scene light and shadow rendering information is acquired.

[0054] In practical applications, the target light and shadow rendering rule information is a set of parameters used to define the lighting rendering process in the virtual scene; the target shadow rendering information is shadow rendering data generated based on the light and shadow rendering configuration sub-information.

[0055] The target lighting and shadow rendering rule information can be understood as a set of parameters used to define the lighting rendering process in the virtual scene. These parameters include lighting type (such as parallel light, point light, spotlight), lighting intensity, reflection probe configuration, etc. For example, on mobile devices, the target lighting and shadow rendering rule information may adopt a simplified lighting process (such as using vertex shaders and pixel shaders instead of compute shaders to achieve deferred lighting) to reduce the computational burden and improve rendering performance. On high-performance devices, more complex lighting effects (such as dynamic global illumination or high-precision reflection probe sampling) may be enabled to provide a higher quality visual experience.

[0056] The target shadow rendering information can be understood as the shadow rendering data generated based on the light and shadow rendering configuration sub-information. These data include shadow maps, shadow filtering algorithm results, etc. For example, on mobile devices, the target shadow rendering information may use a simplified shadow filtering algorithm (such as percentage progressive filtering) to reduce the target device computing resource consumption and balance performance and effect. On high-performance devices, more complex shadow data (such as high-quality soft shadows or dynamic shadow mapping) may be generated to achieve more realistic shadow effects.

[0057] In the above manner, the target light and shadow rendering rule information and the target shadow rendering information together constitute the core part of the virtual scene light and shadow rendering information. Based on this information, the lighting and shadow rendering data adapted to the performance of different devices can be generated, thereby achieving a balance between performance and quality.

[0058] Furthermore, generating virtual scene object material rendering information according to the to-be-rendered scene information and the surface material configuration sub-information includes: Determining a basic color buffer rule, a material attribute buffer rule, and a material property buffer rule based on the surface material configuration sub-information; Processing the to-be-rendered scene information based on the basic color buffer rule, the material attribute buffer rule, and the material property buffer rule, respectively, to generate a basic color buffer table, a material attribute buffer table, and a material property buffer table; The virtual scene object material rendering information is generated according to the basic color buffer table, the material attribute buffer table and the material property buffer table.

[0059] In practical applications, basic color buffer rules are rules that determine how to store and process the basic colors of object surfaces; material attribute buffer rules are rules that define how to store and process material attributes (such as normals and metallicity); material property buffer rules are rules that describe how to store and process material properties (such as reflective characteristics); basic color buffer table is a table for storing basic color data generated according to basic color buffer rules; material attribute buffer table is a table for storing material attribute data generated according to material attribute buffer rules; material property buffer table is a table for storing material property data generated according to material property buffer rules.

[0060] The basic color buffer rule can be understood as a rule for determining how to store and process the basic color of an object surface. It defines the storage format and processing method of basic color data. For example, as mentioned in the reference paragraph, the basic color buffer rule changes the original way of storing diffuse color to storing basic color and removes the influence of metalness information. This change in rule can optimize data storage, reduce redundant information, and ensure the consistency of rendering effects.

[0061] The material attribute buffer rule can be understood as a rule that defines how to store and process material attributes such as normals and metalness. It determines the storage format and encoding method of material attribute data. For example, as mentioned in the reference paragraph, the material attribute buffer rule adjusts the storage of normal information from higher precision to lower precision, and uses the saved storage space to store metalness information. This rule design can reduce memory usage and bandwidth consumption while ensuring visual effects.

[0062] The material property buffer rule can be understood as a rule for describing how to store and process material properties (such as reflectance). It defines the storage method and processing logic of material property data. For example, as mentioned in the reference paragraph, the buffer rule originally used to store data such as reflectance properties has been simplified, some information (such as coating masks) has been directly removed, and other information has been restored through base color and metalness. This change in the rule can further optimize storage space while maintaining the visual performance of the material.

[0063] The base color buffer table can be understood as a table that stores base color data generated according to the base color buffer rules. It is a data structure used to store the base color of the object surface in the rendering process. For example, in the reference paragraph, the base color buffer table stores the base color information of the object, removing the influence of metalness, thereby simplifying data storage and improving rendering efficiency.

[0064] The material attribute buffer table can be understood as a table for storing material attribute data generated according to the material attribute buffer rules. It is used to store the material attribute information of the object, such as normal and metalness. For example, as mentioned in the reference paragraph, the material attribute buffer table achieves more efficient data utilization in limited storage space by adjusting the storage accuracy of normal information and using the saved space to store metalness information.

[0065] The material property buffer table can be understood as a table that stores material property data generated according to the material property buffer rules. It is used to store material property information of objects, such as reflection characteristics. For example, as mentioned in the reference paragraph, the material property buffer table reduces the use of storage space by simplifying the storage content and removing unnecessary characteristic information, while restoring the necessary material properties through other data (such as base color and metalness). This design optimizes rendering performance while ensuring visual effects.

[0066] Step 106: Render the scene information to be rendered according to the virtual scene rendering reference information to obtain a target virtual scene image for the target device.

[0067] In practical applications, the target virtual scene image is the final rendering result generated according to the rendering configuration information of the target device and the scene information to be rendered; the target virtual scene image can be understood as the final image generated after processing the scene information to be rendered through the virtual scene rendering reference information. It is the final output of the rendering process and is presented directly to the user. For example, on a mobile phone platform, the target virtual scene image may be achieved by simplifying the shadow filtering algorithm, adjusting the lighting process, and optimizing the generation method of the buffer table to ensure that good visual effects can be presented under limited performance. At the same time, the switch of post-processing effects and the application of image super-resolution technology will also have an important impact on the quality of the target virtual scene image.

[0068] Considering that some data is frequently accessed during the rendering process, if the above data is determined as read-only information, the reading performance can be optimized. Before rendering the scene information to be rendered according to the virtual scene rendering reference information and obtaining the target virtual scene image for the target device, the method further includes: Determine scene rendering read-only information according to the scene rendering configuration information and the scene information to be rendered; The scene information to be rendered is rendered according to the scene rendering read-only information and the virtual scene rendering reference information to obtain a target virtual scene image for the target device.

[0069] In practical applications, scene rendering read-only information is data that is frequently accessed and does not need to be modified during the rendering process; scene rendering read-only information can be understood as data that is frequently accessed but does not need to be modified during the rendering process. These data usually include static material properties, lighting information, or other rendering-related configuration data. By setting these data to read-only information, you can optimize reading performance, reduce cache consistency issues on the target device, and improve rendering efficiency. For example, as mentioned in the reference paragraph, adjusting some frequently accessed data structures from read-write to read-only, such as from SSBO (ShaderStorage Buffer Object) to UBO (Uniform Buffer Object), can significantly improve rendering performance, especially in scenes that require fast access to static data.

[0070] Further, rendering the scene information to be rendered according to the virtual scene rendering reference information to obtain a target virtual scene image for the target device includes: Rendering the scene information to be rendered according to the virtual scene rendering reference information to obtain an initial virtual scene image for the target device, wherein the image resolution corresponding to the initial virtual scene image is a first image resolution; A target virtual scene image is generated according to the initial virtual scene image, wherein an image resolution corresponding to the target virtual scene image is a second image resolution, and the second image resolution is greater than the first image resolution.

[0071] In practical applications, the initial virtual scene image is the original image rendered according to the virtual scene rendering reference information; the first image resolution is the resolution of the initial virtual scene image; and the second image resolution is the resolution of the target virtual scene image processed by super-resolution technology.

[0072] The initial virtual scene image can be understood as the original image generated by rendering according to the virtual scene rendering reference information. These images are usually generated based on the rendering capabilities of the target device and the scene requirements, and the resolution may be low to meet performance requirements. For example, on a mobile device, the initial virtual scene image may use a lower resolution (such as 720p) to reduce the computing burden of the computing device and improve rendering performance. Although this image has a low resolution, it already contains the core visual information of the scene, providing a basis for subsequent super-resolution processing.

[0073] The first image resolution can be understood as the resolution of the initial virtual scene image. This resolution is usually determined based on the performance requirements of the target device and the complexity of the scene. For example, on a performance-constrained device, the first image resolution may be set to a lower value (such as below 1080p) to balance rendering performance and visual effects. On a high-performance device, it may be set to a higher resolution (such as 2K or 4K) to fully utilize hardware performance and improve image quality.

[0074] The second image resolution can be understood as the resolution of the target virtual scene image after being processed by super-resolution technology. This resolution is usually higher than the resolution of the initial virtual scene image, and is intended to improve the image's detail performance and visual quality. For example, on a mobile device, the resolution of the initial virtual scene image may be 720p, and after being processed by super-resolution technology, the resolution of the target virtual scene image may be increased to 1080p or higher, thereby providing clearer visual effects without significantly increasing the rendering load.

[0075] In the above manner, the initial virtual scene image, the first image resolution, and the second image resolution together constitute the core link of virtual scene rendering. The initial virtual scene image provides basic data for the rendering process, the first image resolution ensures the balance between rendering performance and quality, and the second image resolution further improves the visual performance of the image through super-resolution technology. For example, on mobile devices, by generating a lower resolution initial virtual scene image and combining super-resolution technology to generate a high-resolution target virtual scene image, high-quality rendering effects can be achieved with limited hardware resources. On high-performance devices, higher initial resolution and more complex super-resolution algorithms can be used to give full play to hardware performance and provide a more realistic visual experience.

[0076] The scheme of the embodiment of this specification is applied to automatically match the rendering strategy of performance priority or image quality priority through device type identification and performance grading mechanism, provide dynamic light source simplification and material compression algorithm for low-performance devices, and retain physical lighting calculation and multi-layer material superposition characteristics for high-performance devices. The light and shadow and material processing flow is disassembled based on hardware capabilities, and standardized rendering data is generated through basic color buffering, attribute layered analysis and multi-level buffering rules, so that the mobile terminal can maintain the sense of material detail while reducing the real-time computing load. Combined with the resolution adaptive mechanism, efficient downsampling rendering of low-power devices and super-resolution enhanced output of high-performance devices are achieved under the unified resource architecture, so that cross-platform projects do not need to produce multiple sets of model maps, so that the mobile terminal can smoothly run computer-level image quality resources, while allowing the computer to call more complex rendering methods to maintain its good visual effects.

[0077] The following combination Figure 2 Taking the application of the virtual scene rendering method provided in this specification in game scene rendering as an example, the virtual scene rendering method is further described. Figure 2 A processing flow chart of a game scene rendering method provided by an embodiment of the present specification is shown, which specifically includes the following steps.

[0078] Step 202: Obtain the target device type corresponding to the target device.

[0079] Step 204: When the target device type is a first type device, determine that the scene rendering configuration information corresponding to the target device is performance scene rendering configuration information.

[0080] Step 206: parse the performance scene rendering configuration information, and obtain the light and shadow rendering configuration sub-information and the surface material configuration sub-information.

[0081] Step 208: Determine the target light and shadow rendering rule information corresponding to the target device based on the light and shadow rendering configuration sub-information.

[0082] Step 210: Generate target shadow rendering information according to the scene information to be rendered and the light and shadow rendering configuration sub-information.

[0083] Step 212: Based on the surface material configuration sub-information, determine the basic color buffer rule, material attribute buffer rule and material property buffer rule.

[0084] Step 214: Process the scene information to be rendered based on the basic color buffer rule, the material attribute buffer rule, and the material property buffer rule, respectively, to generate a basic color buffer table, a material attribute buffer table, and a material property buffer table.

[0085] Step 216: Generate virtual scene object material rendering information according to the basic color buffer table, the material attribute buffer table and the material property buffer table.

[0086] Step 218: Combine the above-mentioned target light and shadow rendering rule information, target shadow rendering information, basic color buffer table, material attribute buffer table and material property buffer table to generate lighting rendering information, and render the image based on the lighting rendering information to obtain an initial virtual scene image.

[0087] Step 220: Super-resolution the initial virtual scene image to obtain a target virtual scene image with a higher resolution.

[0088] The scheme of the embodiment of this specification is applied to trigger the differentiated rendering pipeline through the device type judgment mechanism. When it is identified as a low-performance device, dynamic light source clipping and material attribute channel compression technology are automatically enabled to remove high-energy subsurface scattering effects while maintaining basic diffuse reflection and normal details. Based on the surface material configuration sub-information, multi-level buffer rules are implemented to separate the basic color, metalness, and roughness, so that the mobile terminal can avoid performance fluctuations caused by real-time reflection probe updates by pre-calculating the material attribute buffer table. The mobile terminal can smoothly run computer-level image quality resources, while allowing the computer to call more complex rendering methods to maintain its better visual effects.
