Member Function Documentation

GLuint gpu_coverage::AbstractProgram::createShader	(	const GLenum	shaderType,
		const GLchar *const	code,
		const char *const	name
	)		const

protected

Create a shader from source code.

Parameters

[in]	shaderType	Shader type GL_VERTEX_SHADER, GL_FRAGMENT_SHADER, ...
[in]	code	Source code for the shader.

bool gpu_coverage::AbstractProgram::isReady ( ) const

inline

Returns true if the program is ready to be used.

bool gpu_coverage::AbstractProgram::link ( const char *const name ) const

protected

Link the associated shader stages.

Parameters

name	Human-readable program name for debugging.

GLuint gpu_coverage::AbstractProgram::loadShader	(	const GLenum	shaderType,
		const char *const	filename
	)		const

protected

Create a shader from a file.

Parameters

[in]	shaderType	Shader type GL_VERTEX_SHADER, GL_FRAGMENT_SHADER, ...
[in]	code	File name of the shader source code file.

static void gpu_coverage::AbstractProgram::setOpenGLVersion ( )

static

Reads versions and available extensions from the GPU.

This method must be called after initializing OpenGL and before instantiating any shader program.
