Detailed Description

A class used to create shader programs later on. A ShaderConfiguration should be added once to the ShaderConfigurationFactory, then the factory must be used to retrieve the added shader configurations. Typical use case : **************************** CREATION **************************** // Create the shader configuration once (see MainApplication::addBasicShaders for example) ShaderConfiguration config("MyConfig"); // Add shader files to the config (note that the file extensions can be whatever you want) config.addShader(ShaderType_VERTEX, "path/to/shader.vert.glsl"); config.addShader(ShaderType_FRAGMENT, "path/to/shader.frag.glsl"); // Same for other shader types. Vertex and fragment are required, other are optional // Note that, for a compute shader, only the compute shader is needed. // Add eventually some properties to the shader configuration config.addProperties( {"USE_MICROFACET;", "MICROFACET_DISTRIBUTION Trowbridge_Reitz;"} ); // Add also some includes if needed config.addInclude{"\"MicrofacetFunctions.glsl\";"); // Add the configuration to the factory ShaderConfigurationFactory::addConfiguration(config);

**************************** USAGE **************************** // When you want to reuse created shader configurations, just set it using auto config = ShaderConfigurationFactory::getConfiguration("MyConfig"); // You can then use it to extract the shader from the ShaderProgramManager and use it auto shader = ShaderProgramManager::getInstance()->getShaderProgram(); shader->bind(); ...

Todo: : make configuration and program (in the OpenGL sense) be packed. A shader configuration might contains a ShaderProgram after compiling. This will remove the need for ShaderConfigurationFactory as ShaderManager will offer the same services. Actually, there is redundancy between ShaderConfigurationFactory and ShaderProgramManager

Constructor & Destructor Documentation

◆ ShaderConfiguration() [1/2]

Ra::Engine::Data::ShaderConfiguration::ShaderConfiguration ( const std::string & name )

explicit

Initializes a shader configuration with a name Warning: This does not query the corresponding configuration in the ShaderConfigurationFactory. The proper way to do this is by calling ShaderConfigurationFactory::getConfiguration(name);

Definition at line 47 of file ShaderConfiguration.cpp.

◆ ShaderConfiguration() [2/2]

Ra::Engine::Data::ShaderConfiguration::ShaderConfiguration	(	const std::string &	name,
		const std::string &	vertexShader,
		const std::string &	fragmentShader )

Initializes a configuration with a name, a vertex and a fragment shader This does not add the configuration to the factory ShaderConfigurationFactory::addConfiguration(config) must be called.

Definition at line 50 of file ShaderConfiguration.cpp.
