Detailed Description

Guard for executing plain OpenGL commands.

With the help of this object one can inject custom OpenGL commands into Cornerstone application. The usage of this class is strongly discouraged because it can cause big performance losses. When using more exotic states, user should set the state of OpenGL state machine to the state it was before.

Examples:

LegacyGLExample.cpp.

Constructor & Destructor Documentation

LUMINOUS_API Luminous::CustomOpenGL::CustomOpenGL	(	RenderContext &	r,
		bool	reset = false
	)

Creates guard for the given OpenGL context.

Executes all queued drawing commands in the given context.

Parameters

r	Context to guard.
reset	Do we reset OpenGL state
