mrMeshComponentsAllComponentsMapFree()

MRMESHC_API void mrMeshComponentsAllComponentsMapFree

(

const MRMeshComponentsMap *

map

)

deletes allocated map

mrMeshComponentsGetAllComponentsMap()

MRMESHC_API MRMeshComponentsMap mrMeshComponentsGetAllComponentsMap	(	const MRMeshPart *	mp,
		MRFaceIncidence	incidence )

gets all connected components of mesh part as

1. the mapping: FaceId -> Component ID in [0, 1, 2, ...)
2. the total number of components

mrMeshComponentsGetComponent()

MRMESHC_API MRFaceBitSet * mrMeshComponentsGetComponent	(	const MRMeshPart *	mp,
		MRFaceId	id,
		MRFaceIncidence	incidence,
		bool(*	isCompBd )(MRUndirectedEdgeId) )

returns one connected component containing given face, not effective to call more than once, if several components are needed use getAllComponents

mrMeshComponentsGetLargeByAreaComponents()

MRMESHC_API MRFaceBitSet * mrMeshComponentsGetLargeByAreaComponents	(	const MRMeshPart *	mp,
		float	minArea,
		bool(*	isCompBd )(MRUndirectedEdgeId) )

returns the union of connected components, each having at least given area

MRMESHC_API MRMeshRegions mrMeshComponentsGetLargeByAreaRegions	(	const MRMeshPart *	mp,
		const MRFace2RegionMap *	face2RegionMap,
		int	numRegions,
		float	minArea )

returns

1. the union of all regions with area >= minArea
2. the number of such regions

		MRFaceIncidence	incidence,
		bool(*	isCompBd )(MRUndirectedEdgeId),
		float	minArea,
		int *	numSmallerComponents )

returns the largest by surface area component or empty set if its area is smaller than

Parameters
