Detailed Description

Stores the current shape hints.

This element stores current shape hints. All hints must be set at the same time; to leave any hint as is, use the "AS_IS" enum value.

static SbBool SoShapeHintsElement::isVBOUsed

(

SoState *

state

)

[static]

Indicates if VBO is used from the state.

virtual void SoShapeHintsElement::print

(

FILE *

)

const [virtual]

Prints element (for debugging).

Reimplemented from SoElement.

virtual void SoShapeHintsElement::push

(

SoState *

state

)

[virtual]

Push copies the values from the previous element, so set doesn't have to set them if they are set AS_IS.

Reimplemented from SoElement.

Reimplemented in SoGLShapeHintsElement.

static void SoShapeHintsElement::set	(	SoState *	state,
		SoNode *	,
		SbBool	useVBO
	)			[inline, static]

Indicates if VBO is used from the state.

static void SoShapeHintsElement::set	(	SoState *	state,
		SoNode *	,
		WindingType	windingType
	)			[inline, static]

static void SoShapeHintsElement::set	(	SoState *	state,
		SoNode *	,
		VertexOrdering	vertexOrdering,

Sets the current shape hints in the state.

Only for VBO usage.

static void SoShapeHintsElement::set	(	SoState *	state,
		WindingType	windingType
	)			[static]

Sets the current shape hints in the state.
