Public Member Functions
	CGFshader (void)
	Base constructor.
	CGFshader (const char *vsFile, const char *fsFile)
	Main constructor. Loads and validates the vertex and fragment shaders specified by vsFile and fsFile, using init().
virtual	~CGFshader (void)
	Base destructor.
virtual void	init (const char *vsFile, const char *fsFile)
	Loads and validates the vertex and fragment shaders specified by vsFile and fsFile, using init().
virtual void	update ()
	Updates the shader parameters (uniforms). In this base implementation, it updates the time uniform (if it exists) with CGFapplication::getTime().
virtual void	update (float time)
	Updates the time uniform (if it exists) with the value time.
virtual void	bind ()
	Binds (activates) the shader.
virtual void	unbind ()
	Unbinds (deactivates) the shader, and reactivates the fixed-function pipeline.
unsigned int	id ()
	Returns the shader id.
