Function Documentation

GU_API void GU_Classify::classifyPointsByEdgeConnectivity	(	const GEO_Detail &	gdp,
		const GA_PointGroup *	point_group,
		const GA_PrimitiveGroup *	prim_closure,
		const UT_Map< GA_Offset, exint > &	class_map,
		UT_Classifier &	point_classifier
	)

Classify points by edge connectivity, so two points will be in the same class iff they are connected by an edge.

prim_closure is optional

GU_API void GU_Classify::classifyPointsByEdgeConnectivity	(	const GEO_Detail &	gdp,
		const UT_Map< GA_Offset, exint > *	class_map,
		UT_Classifier &	point_classifier
	)

Classify points by edge connectivity, so two points will be in the same class iff they are connected by an edge.

Class map is optional. If not present, the point indices are used.

GU_API void GU_Classify::classifyPointsBySharedPrims	(	const GEO_Detail &	gdp,
		const GA_PointGroup *	point_group,
		const GA_PrimitiveGroup *	candidate_prims,
		const UT_Map< GA_Offset, exint > &	class_map,
		UT_Classifier &	point_classifier
	)

Classify points by shared primitive references, so two points will be in the same class iff they are both referenced by a common primitive.

candidate_prims is optional

GU_API void GU_Classify::classifyPrimsBySharedPoints	(	const GEO_Detail &	gdp,
		const GA_PrimitiveGroup *	prim_group,
		const GA_PointGroup *	point_closure,
		const UT_Map< GA_Offset, exint > &	class_map,
		UT_Classifier &	prim_classifier
	)

Classify primitives by shared point references, so two primitives will be in the same class iff they both reference a common point.

point_closure is optional

GU_API void GU_Classify::partitionBreakpointsBySpline	(	const GEO_Detail &	gdp,
		const GA_BreakpointGroup *	bkpt_group,
		UT_Array< GA_Breakpoint > &	class_bkpts,
		UT_ExintArray &	class_start_indices
	)

Partition a group of breakpoints (or all breakpoints if no group is given) into a single array that groups all breakpoints classified to the same class together. Both the classes and the member breakpoints in each are in the order encountered by a standard traversal.

The class_start_indices array is set to contain the start index into the class_bkpts for each class, plus an extra entry containing the number of entries of class_bkpts.

GU_API void GU_Classify::partitionEdgesByConnectivity	(	const GEO_Detail &	gdp,
		const GA_EdgeGroup &	edge_group,
		UT_Array< GA_Edge > &	class_edges,
		UT_ExintArray &	class_start_indices
	)

Partition a group of edges into a single array that groups all edges classified to the same class together. Both the classes and the member edges in each are in the order encountered by a standard traversal.

The class_start_indices array is set to contain the start index into the class_edges for each class, plus an extra entry containing the number of entries of class_edges.

GU_API void GU_Classify::partitionPointsByEdgeConnectivity	(	const GEO_Detail &	gdp,
		const GA_PointGroup *	point_group,
		const GA_PrimitiveGroup *	prim_closure,
		GA_OffsetArray &	class_points,
		UT_ExintArray &	class_start_indices
	)

Partition a group of points (or all points if no group is given) into a single array that groups all primitives classified to the same class together. Both the classes and the member points in each are in the order encountered by a standard traversal.

The class_start_indices array is set to contain the start index into the class_points for each class, plus an extra entry containing the number of entries of class_points.

GU_API void GU_Classify::partitionPrimsBySharedPoints	(	const GEO_Detail &	gdp,
		const GA_PrimitiveGroup *	prim_group,
		GA_OffsetArray &	class_prims,
		UT_ExintArray &	class_start_indices
	)

Partition a group of primitives (or all primitives if no group is given) into a single array that groups all primitives classified to the same class together. Both the classes and the member primitives in each are in the order encountered by a standard traversal.

The class_start_indices array is set to contain the start index into the class_prims for each class, plus an extra entry containing the number of entries of class_prims.
