Member Function Documentation

◆ Destroy()

void ON_MeshVertexFaceMap::Destroy ( )

◆ FaceCount()

unsigned int ON_MeshVertexFaceMap::FaceCount ( ) const

Returns: Number a faces.

◆ operator=()

ON_MeshVertexFaceMap& ON_MeshVertexFaceMap::operator= ( const ON_MeshVertexFaceMap & )

◆ SetFromFaceList()

bool ON_MeshVertexFaceMap::SetFromFaceList	(	unsigned int	vertex_count,
		const class ON_MeshFaceList &	face_list,
		bool	bMapInvalidFaces
	)

◆ SetFromMesh()

bool ON_MeshVertexFaceMap::SetFromMesh	(	const ON_Mesh *	mesh,
		bool	bMapInvalidFaces
	)

◆ VertexCount()

unsigned int ON_MeshVertexFaceMap::VertexCount ( ) const

Returns: Number a vertices.

◆ VertexFaceCount()

unsigned int ON_MeshVertexFaceMap::VertexFaceCount ( unsigned int vertex_index ) const

Parameters: vertex_index - [in] Index of a vertex. Returns: The number of faces that reference the vertex. Remarks: If vertex_index is out of range, then zero is returned.

◆ VertexFaceList()

const unsigned int* ON_MeshVertexFaceMap::VertexFaceList ( unsigned int vertex_index ) const

Parameters: vertex_index - [in] Index of a vertex. Returns: An array of indices of faces that reference the vertex. The array has length VertexFaceCount(vertex_index). When the value of VertexFaceCount(vertex_index) is zero, this function returns a null pointer. Remarks: If vertex_index is out of range, then null is returned.

◆ VertexFaceMap()

const unsigned int* const* ON_MeshVertexFaceMap::VertexFaceMap ( ) const

Description: Expert user function for situations where rapid access to the vertex face list information is required. Returns: An array of VertexCount() unsigned int arrays that list the indices of faces that reference each vertex. VertexFaceMap()[vertex_index] is null if zero faces reference the indicated vertex. Otherwise, VertexFaceMap()[vertex_index][0] is the number of faces that reference the vertex and VertexFaceMap()[vertex_index][1,...,n] are the indices of those faces, where "n" is the value of VertexFaceMap()[vertex_index][0].
