Detailed Implementation

[0016] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] In this embodiment of the invention, the shader can be a shader from OpenGL (Open Graphics Library). OpenGL is a cross-language, cross-platform application programming interface (API) for rendering 2D and 3D vector graphics. This interface consists of nearly 350 different function calls, used for everything from simple graphics drawing to complex 3D scene rendering. OpenGL is one of the most widely accepted APIs for processing 2D / 3D graphics in the video industry. OpenGL supports multiple operating systems, including Windows, Unix-like systems, Linux, and macOS, making applications developed based on OpenGL highly portable. OpenGL is language-independent and supports bindings for multiple programming languages. OpenGL is commonly used in fields such as CAD, virtual reality, scientific visualization programs, and video game development. Its efficient graphics rendering capabilities and rich API enable developers to create high-quality graphics effects. The technical details include texture mapping, rendering workflow, coordinate systems, and the Shader Language (GLSL). Shaders can be coded using GLSL. GLSL, short for OpenGL Shader Language, is the language used for shading programming in OpenGL. It allows developers to write short, custom programs that execute on the GPU (Graphics Processing Unit) of a graphics card, replacing parts of the traditional fixed rendering pipeline, such as view transformations and projection transformations, making different layers of the rendering pipeline programmable. A shader language is a high-level shader language used to write vertex shaders, fragment shaders, and other types of shader programs. GLSL provides rich syntax and built-in functions, enabling developers to write flexible and efficient shader code. Currently, programs that directly or indirectly use OpenGL for rendering basically require GLSL to render and ultimately display images. Therefore, GLSL plays a crucial role in OpenGL. An OpenGL program typically has one or more shader programs. Before using shaders, OpenGL rendering requires compiling and linking them, and the compilation time directly determines the speed of image display and program startup. Because the shader code in GLSL is a human-readable coding language, the graphics card needs to compile it into machine code that it can recognize before using it. Therefore, each program needs to code its own shaders when it starts up, and the compilation and linking process is relatively slow, especially for complex shaders. To address this, the implementation process of this invention is proposed.

[0018] Reference Figure 1This document illustrates a flowchart of an embodiment of a shader loading method according to the present invention. The shader loading method is used in an electronic device, which is equipped with a cache that stores preloaded shader encoding files. The electronic device described in this embodiment can run OpenGL programs, i.e., open-source graphics library programs. The electronic device is equipped with a cache that stores preloaded shader encoding files. The preloaded shader encoding files are the encoding files corresponding to shaders that have already been loaded before the current shader loading. There can be multiple preloaded shader encoding files. The encoding format of the preloaded shader encoding files can use encoding files of different bases. For example, the preloaded shader encoding files can be binary encoding files.

[0019] The shader loading method may specifically include the following steps: Step 101: When the Open Graphics Library program starts, obtain the information of the shaders to be loaded; When an electronic device launches an open graphics library program, it can obtain information about the shaders to be loaded, including their parameters such as name and encoding language file.

[0020] Step 102: Match the information of the shader to be loaded with the preloaded shader encoding file to determine the first target shader encoding file; The information of the shader to be loaded can be matched one by one with the preloaded shader code files to determine the corresponding first target shader code file. The first target shader code file is the shader code file in the preloaded shader code files that matches the information of the shader to be loaded. The first target shader code file can be a real shader code file, that is, there exists a shader code file that matches the information of the shader to be loaded. The first target shader code file can also be empty, that is, there is no shader code file that matches the information of the shader to be loaded.

[0021] Step 103: When the first target loading shader encoding file is empty, compile based on the information of the shader to be loaded to determine the second target loading shader encoding file; If the first target shader encoding file is empty, it means that the shader corresponding to the shader information to be loaded has not been loaded before. Therefore, the shader information to be loaded can be encoded to generate a second target shader encoding file. The second target shader encoding file is the encoding file corresponding to the shader information to be loaded. The second target shader encoding file is generated using the same encoding format as the preloaded shader encoding file. If the preloaded shader encoding file is a binary file, the second target shader encoding file can also be a binary file.

[0022] Step 104: Load the second target's shader encoding file; Load the second target shader encoding file to complete the loading of the shader to be loaded.

[0023] Step 105: If the first target load shader encoding file is not empty, load the first target load shader encoding file.

[0024] If the first target shader encoding file is not empty, it means that the shader corresponding to the shader information to be loaded has already been loaded. The first target shader encoding file can be loaded directly to complete the loading of the shader to be loaded.

[0025] This invention, in its embodiments, obtains information about shaders to be loaded when the open graphics library program starts; matches this information with preloaded shader encoding files to determine a first target shader encoding file; if the first target shader encoding file is empty, compiles based on the information about the shaders to be loaded to determine a second target shader encoding file; loads the second target shader encoding file; and if the first target shader encoding file is not empty, loads the first target shader encoding file. By using a cache to store preloaded shader encoding files that have already been loaded, during shader loading, the first target shader encoding file corresponding to the already loaded shaders can be directly called, and encoding is only performed on unloaded shaders to determine the second target shader encoding file, thereby shortening compilation time and improving image display speed and program startup and running speed.

[0026] Reference Figure 2 This diagram illustrates a flowchart of another embodiment of the shader loading method of the present invention. The shader loading method is used in an electronic device, which is equipped with a cache that stores pre-loaded shader encoding files. Specifically, the shader loading method may include the following steps: Step 201: When the Open Graphics Library program starts, obtain the information of the shaders to be loaded; When an open graphics library program starts, it can generate information about the shader to be loaded based on the parameters of the shader to be loaded. This information about the shader to be loaded can then be retrieved.

[0027] Step 202: Match the information of the shader to be loaded with the preloaded shader encoding file to determine the first target shader encoding file; The identifiers of the shaders in the shader information to be loaded are matched with the identifiers of the shaders corresponding to each shader encoding file in the preloaded shader encoding file, and the first target shader encoding file is determined based on the matching results.

[0028] In an optional embodiment of the present invention, the shader information to be loaded includes a first shader key string, the preloaded shader encoding file includes a second shader key string, and the step of matching the shader information to be loaded with the preloaded shader encoding file to determine the first target shader encoding file includes: Sub-step S2021: Match the first shader key string with the second shader key string; In this embodiment of the invention, the shader information to be loaded includes a first shader key string, and the preloaded shader encoding file includes a second shader key string. The first key string and the second key string are determined using the same cryptographic solution method. That is, the first key string and the second key string can be matched after being decrypted using the same decryption method. The first shader key string can be matched one by one with the second shader key string of each shader in the preloaded shader encoding file.

[0029] Sub-step S2022: When the first shader key string matches the second shader key string, the preloaded shader encoding file corresponding to the second shader key string is determined as the first target loaded shader encoding file; When the first shader key string matches the second shader key string, that is, the shader corresponding to the shader information to be loaded and the shader corresponding to the second shader key string are the same shader, the preloaded shader encoding file corresponding to the second shader key string can be determined as the first target loaded shader encoding file.

[0030] Sub-step S2023: When the first shader key string does not match the second shader key string, determine that the first target load shader encoding file is empty.

[0031] When the first shader key string does not match any of the second shader key strings, it means that the shader corresponding to the shader information to be loaded is different from the shader corresponding to the preloaded shader encoding file, and the first target shader encoding file can be empty.

[0032] Step 203: When the first target loading shader encoding file is empty, compile based on the information of the shader to be loaded to determine the second target loading shader encoding file; When the first target shader encoding file is empty, meaning the shader corresponding to the shader information to be loaded is being loaded for the first time, encoding can be performed based on the shader information to be loaded, and the generated encoding file is the second target shader encoding file. For example, if the shader information to be loaded includes a text document written by the user using GLSL, this GLSL text document can be compiled using functions such as glCompileShader and glLinkProgram, and the generated binary file will be the second target shader encoding file.

[0033] Step 204: Load the second target's shader encoding file; Then, the second target shader encoding file is loaded to complete the shader loading process. By compiling only the shaders loaded the first time, the overall amount of data for compiling shaders is reduced, thereby improving loading speed.

[0034] Step 205: If the first target load shader encoding file is not empty, load the first target load shader encoding file; If the first target load shader encoding file is not empty, the already loaded first target load shader encoding file can be directly called to complete the loading of the shader.

[0035] Step 206: Associate the second target loading shader encoding file with the information of the shader to be loaded to generate association information; Since the second target shader encoding file is the compiled encoding file of the shader loaded in the first instance, it can be cached. This allows for direct access to the second target shader encoding file the next time the corresponding shader is called, thus shortening loading time. Therefore, the second target shader encoding file can be associated with the information of the shader to be loaded to generate association information.

[0036] In an optional embodiment of the present invention, the step of associating the second target loading shader encoding file with the information of the shader to be loaded to generate association information includes: Sub-step S2061: Hash the second target loaded shader encoding file and the shader information to be loaded to generate a hash value; A hash algorithm can be used as a verification method. The second target shader encoding file and the information of the shader to be loaded are hashed together to generate a unique and corresponding hash value as the association key (index) between the second target shader encoding file and the information of the shader to be loaded.

[0037] Specifically, the information of the shader to be loaded includes the graphics card model and driver version. The step of hashing the second target shader encoding file and the information of the shader to be loaded to generate a hash value includes: hashing the string corresponding to the graphics card model, the string corresponding to the driver version, and the string corresponding to the second target shader encoding file to generate a hash value.

[0038] In practical applications, the information to be loaded for the shader includes the graphics card model and driver version. The graphics card model refers to the model of the graphics processor used by the electronic device, including its performance parameters. The driver version is the version number of the driver service for the electronic device. The strings corresponding to the graphics card model, the driver version, and the second target shader encoding file can be hashed to generate a hash value.

[0039] Sub-step S2062: The hash value is determined as the associated information.

[0040] The calculated hash value is used as the associated information.

[0041] For example, the MD5 algorithm can be used for hashing, such as... Figure 3 As shown, it retrieves the currently used graphics card model and driver version; retrieves all shader code required by the current shader program; performs MD5 hashing on the strings of graphics card model, driver version, and shader code, generates a new string, and returns the generated MD5 string as the key, serving as associated information.

[0042] Step 207: Store the second target loaded shader encoding file and the associated information in the cache to update the preloaded shader encoding file; The second target loads the shader encoding file and associated information together and writes them into the cache, thereby adding the contents of the preloaded shader encoding file, which is used to look up the corresponding shader in the preloaded shader encoding file next time.

[0043] Step 208: Determine the number of matches for the preloaded shader encoding file; It can also determine the number of times the preloaded shader encoding file is matched, and the frequency of calling the shader corresponding to the preloaded shader encoding file can be determined by the number of times the preloaded shader encoding file is matched.

[0044] Step 209: Perform cache management on the preloaded shader encoding file based on the number of matching.

[0045] Based on the number of matches, the frequency of calls is determined. The preloaded shader encoding file is then cached based on the call frequency, which can prevent the cache from becoming too large and affecting the operating performance of electronic devices.

[0046] In an optional embodiment of the present invention, the step of managing the cache of the preloaded shader encoding file based on the number of matches includes: when the cache reaches the storage limit, sorting the preloaded shader encoding file in descending order based on the number of matches to determine a buffer sequence; and deleting the preloaded shader encoding file based on the order in the buffer sequence.

[0047] Cache management can also be performed when the cache storage limit is reached. When the cache reaches its storage limit, the preloaded shader code files can be sorted in descending order based on the number of matches, that is, less frequently used preloaded shader code files are moved to the front, generating a buffer sequence. Following the order in this buffer sequence, the corresponding preloaded shader code files are deleted sequentially until the cache capacity meets the requirements.

[0048] For example, the process of cache management control can be referred to Figure 4 This sets a maximum limit on the number of shader programs that can be cached. Each time a cache file is searched, the count of the found cache files is incremented by one, and the files are sorted from largest to smallest based on their counts. If the maximum limit is exceeded, the cache file with the smallest count is deleted to ensure that space is not written to indefinitely.

[0049] To enable those skilled in the art to clearly understand the implementation process of the embodiments of the present invention, an example is used below for illustration. Please refer to the example provided. Figure 5 After the program starts, a key (information about the shader to be loaded) is generated for the shader to be used. This key is then used to look up the shader in the cache. If the shader is not cached, functions such as `glCompileShader` and `glLinkProgram` are called to compile it. Then, the compiled shader binary data is retrieved using the `glGetProgramBinary` function, written to disk, bound to the generated key, and written to the cache file for future lookups.

[0050] If the key is found in the cache, the compiled binary data previously written to disk is read into memory and loaded directly into the graphics card using the glProgramBinary function, saving compilation and linking time and processes.

[0051] It should be noted that, for the sake of simplicity, the method embodiments are all described as a series of actions. However, those skilled in the art should understand that the embodiments of the present invention are not limited to the described order of actions, because according to the embodiments of the present invention, some steps can be performed in other orders or simultaneously. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions involved are not necessarily essential to the embodiments of the present invention.

[0076] Optionally, the method further includes: Determine the number of matches in the preloaded shader encoding file; The preloaded shader encoding file is cached based on the number of matches.

[0078] This invention, in its embodiments, obtains information about shaders to be loaded when the open graphics library program starts; matches this information with preloaded shader encoding files to determine a first target shader encoding file; if the first target shader encoding file is empty, compiles based on the information about the shaders to be loaded to determine a second target shader encoding file; loads the second target shader encoding file; and if the first target shader encoding file is not empty, loads the first target shader encoding file. By using a cache to store preloaded shader encoding files that have already been loaded, during shader loading, the first target shader encoding file corresponding to the already loaded shaders can be directly called, and encoding is only performed on unloaded shaders to determine the second target shader encoding file, thereby shortening compilation time and improving image display speed and program startup and running speed.
