Function Documentation

mrMeshTopologyFaceSize()

MRMESHC_API size_t mrMeshTopologyFaceSize

(

const MRMeshTopology *

top

)

returns the number of face records including invalid ones

mrMeshTopologyFindHoleRepresentiveEdges()

MRMESHC_API MREdgePath * mrMeshTopologyFindHoleRepresentiveEdges

(

const MRMeshTopology *

top

)

returns one edge with no valid left face for every boundary in the mesh

mrMeshTopologyFindNumHoles()

MRMESHC_API int mrMeshTopologyFindNumHoles	(	const MRMeshTopology *	top,
		MREdgeBitSet *	holeRepresentativeEdges )

returns the number of hole loops in the mesh;

Parameters

holeRepresentativeEdges

optional output of the smallest edge id with no valid left face in every hole

mrMeshTopologyGetLeftTriVerts()

MRMESHC_API void mrMeshTopologyGetLeftTriVerts	(	const MRMeshTopology *	top,
		MREdgeId	a,
		MRVertId *	v0,
		MRVertId *	v1,
		MRVertId *	v2 )

gets 3 vertices of given triangular face; the vertices are returned in counter-clockwise order if look from mesh outside

mrMeshTopologyGetTriangulation()

MRMESHC_API MRTriangulation * mrMeshTopologyGetTriangulation

(

const MRMeshTopology *

top

)

returns three vertex ids for valid triangles (which can be accessed by FaceId), vertex ids for invalid triangles are undefined, and shall not be read

mrMeshTopologyGetTriVerts()

MRMESHC_API void mrMeshTopologyGetTriVerts	(	const MRMeshTopology *	top,
		MRFaceId	f,
		MRVertId *	v0,
		MRVertId *	v1,
		MRVertId *	v2 )

gets 3 vertices of given triangular face; the vertices are returned in counter-clockwise order if look from mesh outside

mrMeshTopologyGetValidFaces()

MRMESHC_API const MRFaceBitSet * mrMeshTopologyGetValidFaces

(

const MRMeshTopology *

top

)

returns cached set of all valid faces

mrMeshTopologyGetValidVerts()

MRMESHC_API const MRVertBitSet * mrMeshTopologyGetValidVerts

(

const MRMeshTopology *

top

)

returns cached set of all valid vertices

mrMeshTopologyPack()

MR_EXTERN_C_BEGIN MRMESHC_API void mrMeshTopologyPack

(

MRMeshTopology *

top

)

tightly packs all arrays eliminating lone edges and invalid faces and vertices
