Inheritance diagram for SoGLViewingMatrixElement:

Public Member Functions
virtual void	init (SoState *state)
	Override init() and push() to copy state pointer.
virtual void	push (SoState *state)
	Pushes/pops element.
virtual void	pop (SoState state, const SoElement prevTopElement)
	Override pop() method so side effects can occur in GL.
Static Public Member Functions
static void	initClass ()
	Initializes the SoGLViewingMatrixElement class.
static uint32_t	getNodeId (SoState *state)
	Used by SoGLModelMatrixElement when it need to figure out if this element has changed between a glPushMatrix() and a glPopMatrix():
Protected Member Functions
virtual void	setElt (const SbMatrix &matrix)
	Sets the matrix in an instance. Has GL side effects.
virtual	~SoGLViewingMatrixElement ()

Detailed Description

Overrides the virtual methods on SoViewingMatrixElement to send the matrix to GL when necessary.

Note that this class relies on SoViewingMatrixElement to store the matrix in the instance.
