This command is a shortcut for setting the render node as a HUD. The command is equivalent to performing the following operations on the render node:
node.setInheritView(False)
node.setScene(None,True)
node.setClearMask(0)
node.setBuffer(viz.RENDER_FRAME_BUFFER)
node.setSize(-1,-1)
node.setProjectionMatrix(viz.Matrix.ortho2D(left,right,bottom,top))
node.setAutoClip(False)
node.setImplicitBufferMask(viz.GL_DEPTH_BUFFER_BIT, viz.MASK_REMOVE)
node.disable(viz.DEPTH_TEST)
node.disable(viz.LIGHTING)
node.appearance(viz.TEXREPLACE)
If 'renderQuad' is True, Vizard will automatically add a fullscreen quad to the render node.
