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.

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.

If vertex_index is out of range, then null is returned.

VertexFaceMap()

const unsigned int* const* ON_MeshVertexFaceMap::VertexFaceMap

(

)

const

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].
