[0040] Research has found that in related technologies, developers often need to write a set of shader codes for each platform, and generate scene rendering data for scene rendering on each platform after compilation. This method has high time and labor costs and is inefficient.

[0041] Based on the above research, the present disclosure provides a shader code compilation method, apparatus, computer equipment and storage medium, by obtaining a shader code including a first target shader code applicable to a first rendering platform, a second target shader code applicable to a second rendering platform, and a third target shader code applicable to both the first rendering platform and the second rendering platform; based on the first target shader code and the third target shader code, a first compilation result corresponding to the first rendering platform is generated; and based on the second target shader code and the third target shader code, a second compilation result corresponding to the second rendering platform is generated. In this way, by writing a set of shader codes and compiling them, the shader code compilation operation under multiple rendering platforms can be completed, thereby saving time and labor costs and improving development efficiency.

[0042] To facilitate understanding of the present embodiment, a shader code compilation method disclosed in the embodiment of the present disclosure is first introduced in detail. The execution subject of the shader code compilation method provided in the embodiment of the present disclosure is generally a computer device with certain computing capabilities, and the computer device includes, for example: a terminal device or a server or other processing device, and the terminal device may be a user equipment (UE), a mobile device, a user terminal, etc. In some possible implementations, the shader code compilation method may be implemented by a processor calling a computer-readable instruction stored in a memory.

[0043] See also Figure 1 As shown, it is a flowchart of a shader code compilation method provided by an embodiment of the present disclosure, the method includes S101-S102, wherein:

[0044] S101: Obtain shader code to be compiled; wherein the shader code includes a first target shader code applicable to a first rendering platform, a second target shader code applicable to a second rendering platform, and a third target shader code applicable to both the first rendering platform and the second rendering platform; the first rendering platform and the second rendering platform are used to perform content rendering under the same type of operating system; the rendering feature information in a first geometry buffer of the first rendering platform referred to by the third target shader code is the same as the rendering feature information in a second geometry buffer of the second rendering platform referred to by the third target shader code.

[0045] S102: Generate a first compilation result corresponding to the first rendering platform based on the first target shader code and the third target shader code; and generate a second compilation result corresponding to the second rendering platform based on the second target shader code and the third target shader code.

[0046] The following is a detailed description of the above steps.

[0047] For S101, the first rendering platform may be the Adreno platform of the Android operating system; the second rendering platform may be the Mali platform of the Android operating system; the shader code may also include a fourth target shader code applicable to a third rendering platform, and a fifth target shader code applicable to a fourth rendering platform, the third rendering platform may be the PC platform of the Microsoft operating system, and the fourth rendering platform may be the Metal platform of the iOS operating system.

[0048] Specifically, the rendering feature information in the first geometry buffer includes at least one of object self-luminous information, fog effect information, normal information, roughness information, metal rendering information, reflectivity information, occlusion information, environment information, shadow information, and fog effect intensity information; the rendering feature information in the second geometry buffer includes at least one of object self-luminous information, fog effect information, normal information, roughness information, metal rendering information, reflectivity information, occlusion information, environment information, and depth information.

[0049] Exemplarily, the buffer data in the first geometry buffer may be as shown in Table 1 below:

[0050] Table 1

[0051] MRT0 blend add emission&Fog(R11G11B10) MRT1 encodeNormal.xy,roughness,metallic(scattering strength)(RGBA8) MRT2 albedo,occlusion(RGBA8) MRT3 envReflectionSlot,0,shadowMask,fogStrength(RGBA8)

[0052] In Table 1, MRT0 to MRT3 represent rendering targets 0 to 3. The rendering targets are video memory buffers used to render pixels. The shader can perform scene rendering through the rendering targets. The Multiple Render Targets (MRT) technology can perform scene rendering according to each rendering target at different stages of scene rendering through the binding relationship between the rendering feature information stored in the buffer and the rendering target, thereby improving the scene rendering efficiency.

[0053] Specifically, in the first row of Table 1, R11G11B10 indicates that the RT format when storing rendering feature information is R11G11B10 format, and the rendering feature information used by MRT0 is object self-luminous information emission and fog effect information Fog, and the fog effect information Fog includes fog effect color information FogColor and fog effect strength information FogStrength. When the geometry buffer stores the rendering feature information corresponding to MRT0, it can perform data processing on each rendering feature information according to a preset rule, and store the "emission*FogStrength+FogColor" obtained after the data processing, so that when the rendering feature information is used for vertex delayed rendering, the "emission*FogStrength+FogColor" stored in MRT0 is superimposed (summed) with the lighting color (lighting)*fog strength (FogStrength) by blend add, so as to perform fog effect rendering in the vertex rendering pipeline;

[0054] In the second row of Table 1, the RGBA8 indicates that the RT format for storing rendering feature information is the RGBA8 format, and the rendering feature information used by the MRT1 is the normal information encodeNormal.xy, the roughness information roughness, and the metal rendering information metallic (the scattering strength information scatteringstrength can be used when some materials do not use the metal rendering information);

[0055] In the third row of Table 1, the RGBA8 indicates that the RT format for storing rendering feature information is the RGBA8 format, and the rendering feature information used by the MRT2 is the reflectivity information albedo and the occlusion information occlusion. The albedo can be stored in the form of a scattering color map of the object surface, and the occlusion can be stored in the form of an ambient light occlusion map. The corresponding rendering feature information can be obtained by sampling the map;

[0056] In the fourth row of Table 1, the RGBA8 indicates that the RT format for storing rendering feature information is the RGBA8 format, the rendering feature information used by the MRT3 is the environment information envReflectionSlot, the shadow information shadowMask, and the fog effect strength information fogStrength, and 0 indicates a reserved bit.

[0057] Exemplarily, the buffer data in the second geometry buffer may be as shown in Table 2 below:

[0058] Table 2

[0059] MRT0 blend add emission&Fog(R11G11B10) MRT1 encodeNormal.xy,roughness,metallic(scattering strength)(RGBA8) MRT2 albedo,occlusion(RGBA8) MRT3 envReflectionSlot,depth(R32f)

[0060] In Table 2, the contents represented by MRT0~MRT2 are the same as those represented by MRT0~MRT2 in the above Table 1, which are not repeated here. In addition, in the 4th row of Table 2, the R32f indicates that the RT format for storing rendering feature information is the R32 floating point texture format, and the rendering feature information used by the MRT3 is the environment information envReflectionSlot and the depth information depth. When encoding, the envReflectionSlot can have 2 bits and the depth can have 30 bits, so that it can be completely encoded into the MRT3 with a data length of 32 bits (the data length of the R32f format is 32 bits).

[0061] Furthermore, through the buffer data in the above-mentioned first geometry buffer and the second geometry buffer, it can be known that the rendering feature information referred to by the third target shader code includes object self-luminous information, fog effect information, normal information, roughness information, metal rendering information, reflectivity information, and occlusion information (that is, the rendering feature information corresponding to the same MRT0~MRT2 in the first buffer and the second buffer), the rendering feature information referred to by the first target shader code includes environment information, shadow information, and fog effect intensity information (that is, the rendering feature information corresponding to MRT3 corresponding to the first buffer), and the rendering feature information referred to by the second target shader code includes environment information and depth information (that is, the rendering feature information corresponding to MRT3 corresponding to the second buffer).

[0062] In addition, when the third rendering platform is a PC platform and the fourth rendering platform is a Metal platform, the buffer data in the third geometry buffer of the third rendering platform referred to by the fourth target shader code and the buffer data in the fourth geometry buffer of the fourth rendering platform referred to by the fifth target shader code may be the same, and the buffer data in the third geometry buffer and the fourth geometry buffer may be as shown in Table 3 below:

[0063] Table 3

[0064] MRT0 blend add emission&Fog(R11G11B10) MRT1 RT1Depth(R32F) MRT2 encodeNormal.xy,roughness,metallic(scattering strength)(RGBA8) MRT3 albedo,occlusion(RGBA8) MRT4 envReflectionSlot,0,shadowMask,fogStrength(RGBA8)

[0065] In Table 3, the contents represented by MTR0, MTR2, MRT3, and MRT4 are respectively the same as those represented by MRT0, MTR1, MRT2, and MRT3 in Table 1 above, and are not repeated here. In addition, in the second row of Table 3, the R32f indicates that the RT format when storing the rendering feature information is the R32 floating point texture format, and the rendering feature information used by the MRT2 is the depth information depth. When encoding, the depth can have 32 bits, so that it can be completely encoded into the MRT2 with a data length of 32 bits (the data length of the R32f format is 32 bits).

[0066] In summary, by setting the rendering feature information in the geometry buffer for the rendering platforms corresponding to each operating system, the rendering effects of each rendering platform can be similar during delayed rendering, avoiding the situation where the rendering effects of the same rendering scene on different rendering platforms are significantly different.

[0067] In actual applications, since the rendering feature information of the geometric buffers corresponding to the first rendering platform and the second rendering platform are relatively similar, the shader code corresponding to the first rendering platform and the shader code corresponding to the second rendering platform are relatively similar. In order to improve code utilization, the shader code corresponding to the first rendering platform and the shader code corresponding to the second rendering platform can be merged for development. The merged shader code can include a first target shader code applicable to the first rendering platform, a second target shader code applicable to the second rendering platform, and a third target shader code applicable to both the first rendering platform and the second rendering platform.

[0068] In a possible implementation, the first target shader code and the second target shader code are located in a target code section in the shader code to be compiled, and the shader code in the target code section is annotated by a preprocessing instruction Pragma to indicate that the compilation of the first target shader code and the compilation of the second target shader code are respectively performed in the target code section.

[0069] Exemplarily, the shader code of the target code segment may be:

[0070] [DefinePragma(symbol: "gl_ext pls0ut SV_Target0 G_Target0 layout(r11f_g11f_b10f)......")]

[0071] In the above shader code, the compilation mode of rendering target 0 (i.e. Target0) can be set through the definition of Pragma macro. When compiling rendering target 0, the editing result of the first rendering platform is compiled, and SV_Target0 is translated into G_Target0 on the second rendering platform for compilation. The specific data structure of G_Target0 can be in the format of R11G11B10.

[0072] In this way, by marking the target code section with the Pragma macro, the compiler can compile the shader code according to the preset compilation method (that is, when compiling to the preset rendering target, translate it into the content of different rendering platforms for compilation to obtain two compilation results). At the target code section, a section of shader code will be used to compile the compilation results corresponding to the first rendering platform and the second rendering platform respectively; on the other hand, by taking different logical branches according to different rendering platforms during compilation, it is possible to avoid increasing memory for variants, save computing resources consumed when compiling shader code, and improve code compilation efficiency.

[0073] S102: Generate a first compilation result corresponding to the first rendering platform based on the first target shader code and the third target shader code; and generate a second compilation result corresponding to the second rendering platform based on the second target shader code and the third target shader code.

[0074] Here, the first compilation result is used for performing delayed rendering on the Adreno platform, and the second compilation result is used for performing delayed rendering on the Mali platform.

[0075] In a possible implementation, a third compilation result corresponding to the third rendering platform may be generated based on the fourth target shader code; and a fourth compilation result corresponding to the fourth rendering platform may be generated based on the fifth target shader code.

[0076] Among them, the third rendering platform is used for content rendering under the Microsoft operating system, for example, delayed rendering can be performed based on the third compilation result; the fourth rendering platform is used for content rendering under the iOS operating system, for example, delayed rendering can be performed based on the fourth compilation result.

[0077] Specifically, when performing the delayed rendering, the following two steps may be included:

[0078] In the first step, the scene in the area to be rendered can be rendered by storing the rendering feature information (such as normal vector, reflection coefficient, etc.) in the geometry buffer to achieve preliminary rendering of the area to be rendered; in the second step, the stored rendering feature information can be read from the geometry buffer, and the rendering content such as pixel color can be calculated based on the rendering feature information, so as to perform more refined scene rendering based on the calculation results, thereby achieving a more realistic scene rendering effect.

[0079] The shader code compilation method provided by the embodiment of the present disclosure obtains a shader code including a first target shader code applicable to a first rendering platform, a second target shader code applicable to a second rendering platform, and a third target shader code applicable to both the first rendering platform and the second rendering platform; based on the first target shader code and the third target shader code, a first compilation result corresponding to the first rendering platform is generated; and based on the second target shader code and the third target shader code, a second compilation result corresponding to the second rendering platform is generated. In this way, by writing a set of shader codes and compiling them, the shader code compilation operation under multiple rendering platforms can be completed, thereby saving time and labor costs and improving development efficiency.

[0080] Those skilled in the art will appreciate that, in the above method of specific implementation, the order in which the steps are written does not imply a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of the steps should be determined by their functions and possible internal logic.

[0081] Based on the same inventive concept, the embodiments of the present disclosure also provide a shader code compilation device corresponding to the shader code compilation method. Since the principle of solving the problem by the device in the embodiments of the present disclosure is similar to the above-mentioned shader code compilation method in the embodiments of the present disclosure, the implementation of the device can refer to the implementation of the method, and the repeated parts will not be repeated.

[0082] Reference Figure 2 As shown, it is a schematic diagram of the architecture of a shader code compilation device provided by an embodiment of the present disclosure, and the device includes: an acquisition module 201 and a generation module 202; wherein,

[0083] The acquisition module 201 is used to acquire a shader code to be compiled; wherein the shader code includes a first target shader code applicable to a first rendering platform, a second target shader code applicable to a second rendering platform, and a third target shader code applicable to both the first rendering platform and the second rendering platform; the first rendering platform and the second rendering platform are used to perform content rendering under the same type of operating system; the rendering feature information in the first geometry buffer of the first rendering platform referred to by the third target shader code is the same as the rendering feature information in the second geometry buffer of the second rendering platform referred to by the third target shader code;
