Public Member Functions
virtual void	init (SoState *state)
	Initializes element.
virtual void	push (SoState *state)
	Push copies the values from the previous element, so set doesn't have to set them if they are set AS_IS.
virtual SbBool	matches (const SoElement *elt) const
	Returns TRUE if the hints match in both elements.
virtual SoElement *	copyMatchInfo () const
	Create and return a copy of this element.
virtual void	print (FILE *fp) const
	Prints element (for debugging)
Static Public Member Functions
static void	set (SoState *state, VertexOrdering vertexOrdering, ShapeType shapeType, FaceType faceType)
	Sets the current shape hints in the state.
static void	set (SoState *state, SbBool useVBO)
	Sets the VBO usage in the state.
static void	set (SoState state, SoNode , VertexOrdering vertexOrdering, ShapeType shapeType, FaceType faceType)
static void	get (SoState *state, VertexOrdering &vertexOrdering, ShapeType &shapeType, FaceType &faceType)
	Returns current shape hints from the state.
static SbBool	isVBOUsed (SoState *state)
static VertexOrdering	getDefaultVertexOrdering ()
	Returns each default hint.
static ShapeType	getDefaultShapeType ()
static FaceType	getDefaultFaceType ()

static void	initClass ()
	Initializes the SoShapeHintsElement class.

Detailed Description

All three hints must be set at the same time; to leave any hint as is, use the "AS_IS" enum value.
