Public Member Functions
virtual	~ShaderImplementation ()=default
virtual bool	activate (SceneRenderer &renderer)=0
	Activates the shader on the target renderer. Subclasses must override this function with an implementation to contains the renderer-specific activation code they need.
virtual bool	deactivate (SceneRenderer &renderer)=0
	Dectivates the shader on the target renderer. Subclasses must override this function with an implementation to contains the renderer-specific activation code they need.
virtual const ShaderImplementationFactory &	getFactory () const =0
virtual bool	renderCurrentModel (SceneRenderer &renderer)=0
	Using the target renderer, render the current model.
virtual bool	renderCurrentModelGlyphs (SceneRenderer &renderer)=0
	Using the target renderer, render the current model's glyphs.

Detailed Description

Note

The architecture guarantees that a unique ShaderImplementation object will be created for each SceneRendererContext. This means that ShaderImplementation writers can safely store context specific state with the knowledge that the implementation will be used only on that one context.
