Detailed Description

Shader represents a shader-program of OpenGL

Definition at line 8 of file Shader.hpp.

Constructor & Destructor Documentation

Shader ( string const & name )

Constructs a Shader-object. Vertex- and fragment-shader are loaded from files (i.e. "content\\shaders\\" + name + ".vert").

Parameters

name	The name of the shader

Definition at line 4 of file Shader.cpp.

~Shader ( )

Destructs a Shader-object

Definition at line 28 of file Shader.cpp.

Member Function Documentation

void link ( )

private

Links all loaded shaders to a shader-program

Definition at line 88 of file Shader.cpp.

int loadShader	(	string const &	file,
		GLenum	shaderType
	)

private

Loads a shader from a file and compiles it.

Parameters

file	The filename
shaderType	the type of the shader

Returns: The shader-id

Definition at line 34 of file Shader.cpp.

GLint uniform ( string const & name )

Returns the position for the given uniform.

Parameters

name	The uniform-name

Returns: The position
