Detailed Description

The WSGLPickModelShader is a very simple shader that when bound, writes an identifier into the framebuffer for each fragment. When combined with depth buffering, this identifier can then be pulled out of the framebuffer to 'pick' what was selected.

Precondition

An OpenGL context must be bound.

renderModel()

bool renderModel	(	WSGLRenderer &	renderer,
		WSGLRenderItem &	model,
		unsigned	modelIndex
	)

Renders the model. If it has glyphs, glyphs will be rendered instead.
