Detailed Description

Class handling shader construction and managment.

This class can be used to generate vertex-fragment programs or compute shader programs. It handles the reading of the source files and compilation and linking of the source. It also handles the setting of uniforms and can also handle the import of shaders into other shaders.

Member Data Documentation

IMPORT_DIRECTIVE

const std::string Shader::IMPORT_DIRECTIVE = "%%import"

static

Preprocesser directive for import statement. Usage in shader code: <IMPORT_DIRECTIVE> <file>

This directive gets replaced with the code in file before compilation.

SHADER_DIRECTORY

const std::string Shader::SHADER_DIRECTORY = "./assets/shader/"

static

Path to the shader folder
