Function Documentation

MR_PolylineComponents_getAllComponents_1()

MRC_API MR_std_vector_MR_UndirectedEdgeBitSet * MR_PolylineComponents_getAllComponents_1

(

const MR_PolylineTopology *

topology

)

gets all connected components of polyline topology

Note

be careful, if mesh is large enough and has many components, the memory overflow will occur Generated from function MR::PolylineComponents::getAllComponents. Parameter topology can not be null. It is a single object. Never returns null. Returns an instance allocated on the heap! Must call MR_std_vector_MR_UndirectedEdgeBitSet_Destroy() to free it when you're done using it.

MR_PolylineComponents_getAllComponents_2()

MRC_API MR_std_pair_std_vector_MR_UndirectedEdgeBitSet_int * MR_PolylineComponents_getAllComponents_2	(	const MR_PolylineTopology *	topology,
		int	maxComponentCount )

gets all connected components of polyline topology \detail if components number more than the maxComponentCount, they will be combined into groups of the same size

Parameters

maxComponentCount

should be more then 1

Returns

pair components bitsets vector and number components in one group if components number more than maxComponentCount Generated from function MR::PolylineComponents::getAllComponents. Parameter topology can not be null. It is a single object. Never returns null. Returns an instance allocated on the heap! Must call MR_std_pair_std_vector_MR_UndirectedEdgeBitSet_int_Destroy() to free it when you're done using it.

MR_PolylineComponents_getComponent()

MRC_API MR_UndirectedEdgeBitSet * MR_PolylineComponents_getComponent	(	const MR_PolylineTopology *	topology,
		MR_UndirectedEdgeId	id )

returns one connected component containing given undirected edge id, not effective to call more than once, if several components are needed use getAllComponents Generated from function MR::PolylineComponents::getComponent. Parameter topology can not be null. It is a single object. Never returns null. Returns an instance allocated on the heap! Must call MR_UndirectedEdgeBitSet_Destroy() to free it when you're done using it.

MR_PolylineComponents_getNumComponents()

MRC_API MR_uint64_t MR_PolylineComponents_getNumComponents

(

const MR_PolylineTopology *

topology

)

returns the number of connected components in polyline Generated from function MR::PolylineComponents::getNumComponents. Parameter topology can not be null. It is a single object.

MR_PolylineComponents_getUnionFindStructure()

MRC_API MR_UnionFind_MR_UndirectedEdgeId * MR_PolylineComponents_getUnionFindStructure

(

const MR_PolylineTopology *

topology

)

gets union-find structure for given polyline Generated from function MR::PolylineComponents::getUnionFindStructure. Parameter topology can not be null. It is a single object. Never returns null. Returns an instance allocated on the heap! Must call MR_UnionFind_MR_UndirectedEdgeId_Destroy() to free it when you're done using it.
