Problems solved by technology

[0002] When rendering images, you need to use shaders. Shaders have the advantage of being editable, and can achieve various image effects in 3D image rendering without being limited by the fixed rendering pipeline of the graphics card, which greatly improves the image quality. Image quality; using a shader source code to achieve different rendering effects, mainly by adjusting or introducing shader parameters, by modifying or introducing variables, it may introduce GPU (Graphics Processing Unit, graphics processing unit) calculation branches or increase instructions number, reducing the overall execution efficiency of the shader; and modifying or introducing variables cannot achieve all rendering effects. Sometimes it is necessary to change the source code of the shader or the parsing method of the source code to achieve some rendering effects, but directly modify the source code of the shader Doubling the development and maintenance cost of the shader, changing the parsing method of the shader source code increases additional system overhead

Abstract

The invention provides a shader source code multiplexing method and a terminal. The shader source code multiplexing method comprises the following steps: acquiring a shader macro in a shader source code; classifying the shader macros according to functions to generate shader macro combinations; selecting a corresponding shader macro combination according to an actual rendering task, generating a shader macro combination set, and defining the shader macro combination set in the shader source code; compiling the shader source code defining the shader macro combination set to obtain a shader, andrendering an image through the shader; and obtaining the shader macro in the shader source code, and achieving different computing logics by changing the shader macro combination set, namely different shader is generated to achieve different rendering effects, and the different rendering effects can be achieved without modifying the shader source code or changing the analysis mode of the shader source code.
