Detailed Description

A renderer class that captures OpenGL renderings from a viewer object into some offline buffer, using FrameBuffer objects with multisampling.

{
        VOutput<VFrameBuffer>   img;

        MyViewer()
        :img( self(), VFrameBuffer( new GLRenderer(self()) ), "OpenGLViewport", new VCreationPreferences("OpenGL") )

Member Function Documentation

int Wizt::GLRenderer::grab	(	const VRequest &	Context,
		VFrameBuffer::Grab &	,
		const VFrameBuffer::Size &	Sz,
		const RefPtr< VContext::Addendum > &	ContextAddendum
	)		const [virtual]

Virtual grab function, it is supposed to call Grab::retrieve();.

Parameters:

RenderObjects	The objects that should be rendered here.
Context	The VRequest providing the context in which this function is called. It is used to avoid infinite recursions.

Implements Wizt::VFrameBuffer::Renderer.

int Wizt::GLRenderer::grab	(	const VRequest &	Context,
		const VSceneLayers &	RenderObjects,
		VFrameBuffer::Grab &	,
		const VFrameBuffer::Size &	Sz,
		const RefPtr< VContext::Addendum > &	ContextAddendum
	)		const [virtual]

Virtual grab function, it is supposed to call Grab::retrieve();.

Parameters:

RenderObjects	The objects that should be rendered here.
Context	The VRequest providing the context in which this function is called. It is used to avoid infinite recursions.

TODO: EXPORT DEPTH LAYERS AS PARAMETER (Once depth layering works)

TODO: Consider using the VRequest's ROOT VObject as ROOT object here as well since this is/may be an indirectly triggered request.
