using GT_OSDAttributes::AttribId = std::pair<int, bool>

Identifier for an attribute. The first item is the index in the attribute list, the second is whether it's a vertex or a point attribute.

GT_DataArrayHandle GT_OSDAttributes::extractFaceMap	(	const GT_OSDTopology &	top,

Extract a mapping from fine faces at a given refinement level to its corresponding coarse face

GT_FaceSetMapPtr GT_OSDAttributes::extractFaceSets	(	const GT_OSDTopology &	top,
		int	level_index
	)		const

Extract a face map set for a mesh at the given refinement level.

GT_PrimitiveHandle GT_OSDAttributes::extractMesh	(	const GT_OSDTopology &	topology,
		bool	harden,
		int	level = `-1`
	)

Extract a subdivided mesh for the given topology level.

GT_AttributeListHandle GT_OSDAttributes::extractShared	(	const GT_OSDTopology &	top,
		int	level_index,
		bool	harden
	)		const

Extract the shared/point attributes for a mesh at the given refinement level. If harden is false, the attributes lists will point to the temporary buffers (which are over-sized). Passing true to harden will copy out the temporary data into compact arrays.

GT_AttributeListHandle GT_OSDAttributes::extractUniform	(	const GT_OSDTopology &	top,
		int	level_index,
		bool	harden
	)		const

Extract the primitive/face attributes for a mesh at the given refinement level.

GT_AttributeListHandle GT_OSDAttributes::extractVertex	(	const GT_OSDTopology &	top,
		int	level_index,
		bool	harden
	)		const

Extract the vertex/face-varying attributes for a mesh at the given refinement level. See extractShared for help on harden

AttribId GT_OSDAttributes::findAttribute ( const char * name ) const

Find an attribute

template<typename T >

const T* GT_OSDAttributes::getData	(	int	attrib,
		int	index,
		int	seg
	)		const

inline

Return a pointer to the index-th entry in the given attribute array. If the index exceeds or equals the number of coarse vertices (myFineOffset), then the data is located in the fine attribute array. The first element of the fine attribute array has index equal to myFineOffset, so we do pointer arithmetic to shift the array by myFineOffset entries.
