void ACG::SceneGraph::BSplineCurveNodeT< BSplineCurve >::getRenderObjects	(	IRenderer *	_renderer,
		GLState &	_state,
		const DrawModes::DrawMode &	_drawMode,
		const Material *	_mat
	)

overrideprivatevirtual

Deferred draw call with shader based renderer.

The renderer calls this function to collect the geometry that should be rendered from the nodes.

Add any renderable geometry to the renderer via _renderer->addRenderObject()

The material is fetched from the last active material node and may be used to setup Renderobjects, but may as well be ignored.

Note: You should not draw anything yourself in this function.

Parameters

_renderer	The renderer which will be used. Add your geometry into this class
_state	The current GL State when this object is called
_drawMode	The active draw mode
_mat	Current material

Reimplemented from ACG::SceneGraph::BaseNode.
