Some important formulas:.

Ne = 3Nv - Nb + 3B + 6(G-R) Nt = 2Nv - Nb + 2B + 4(G-R)

Ne <= 3Nv + 6(G-R) Nt <= 2Nv + 4(G-R)

Ne ~ 3Nv, Nv >> G, Nv >> R Nt ~ 2Nv, Nv >> G, Nv >> R

Ne = Edges Nt = Facets Nv = Vertices Nb = Boundary vertices B = Boundaries G = Genus (Number of holes) R = components

Member Function Documentation

void MeshComponents::SearchForComponents	(	TMode	tMode,
		const std::vector< unsigned long > &	aSegment,
		std::vector< std::vector< unsigned long > > &	aclT
	)			const

Does basically the same as the method above escept that only the faces in aSegment are regarded.

void MeshComponents::SearchForComponents	(	TMode	tMode,
		std::vector< std::vector< unsigned long > > &	aclT
	)			const

Searches for 'isles' of the mesh.

If tMode is OverEdge then facets sharing the same edge are regarded as connected, if tMode is OverPoint then facets sharing a common point are regarded as connected.
