Detailed Description

Class for maintaining OpenGL shader programs.

The class maintains information about where the shaders are saved on the graphics card. It caches the uniform locations as they are used to speed up the next call.

ShaderProgram shaderProgram;
shaderProgram.loadShader(new VertexShader(vertexShaderString), new FragmentShader(fragmentShaderString));
shaderProgram.use();

Member Function Documentation

void ShaderProgram::backupCurrentShaderProgram

(

)

Saves the shader currently active on the graphics card. This is useful if later calculations may depend on the currently active shader. Then you can save it, perform this shader objects calculation, and restore the previous shader.

Definition at line 66 of file ShaderProgram.cpp.

void ShaderProgram::loadShader	(	IShader *	vertexShader,
		IShader *	fragmentShader
	)

Compiles, links and creates a program of the specified shaders.

Definition at line 27 of file ShaderProgram.cpp.

void ShaderProgram::restorePreviousShaderProgram

(

)

Restores a shader saved by backupCurrentShaderProgram();

Definition at line 70 of file ShaderProgram.cpp.

void ShaderProgram::use

(

)

Activates the shader on the graphics card
