Function Documentation

◆ getAllComponents() [1/3]

MRMESH_API std::vector< VoxelBitSet > MR::FloatGridComponents::getAllComponents	(	const FloatGrid &	grid,
		float	isoValue = 0.0f )

finds separated by iso-value components in grid space (0 voxel id is minimum active voxel in grid)

◆ getAllComponents() [2/3]

MRMESH_API std::vector< UndirectedEdgeBitSet > MR::PolylineComponents::getAllComponents ( const 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

◆ getAllComponents() [3/3]

MRMESH_API std::pair< std::vector< UndirectedEdgeBitSet >, int > MR::PolylineComponents::getAllComponents	(	const 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

◆ getComponent()

MRMESH_API UndirectedEdgeBitSet MR::PolylineComponents::getComponent	(	const PolylineTopology &	topology,
		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

◆ getLargestComponent()

template<typename V >

UndirectedEdgeBitSet MR::PolylineComponents::getLargestComponent ( const Polyline< V > & polyline )

returns largest by length component

◆ getUnionFindStructure()

MRMESH_API UnionFind< UndirectedEdgeId > MR::PolylineComponents::getUnionFindStructure ( const PolylineTopology & topology )

gets union-find structure for given polyline
