Syntax
public class VertexTriangleAdjacency

Constructors

~VertexTriangleAdjacency()

Destructor

Declaration
public ~VertexTriangleAdjacency()

VertexTriangleAdjacency(uint32* indices, int32 indicesCount, uint32 vertexCount = 0, bool computeNumTriangles=true)

Construction from an existing index buffer

Declaration
public VertexTriangleAdjacency(uint32* indices, int32 indicesCount, uint32 vertexCount = 0, bool computeNumTriangles=true)
Parameters
uint32 indices

The index buffer.
int32 indicesCount

The number of triangles in the buffer.
uint32 vertexCount

The number of referenced vertices. This value is computed automatically if 0 is specified.
bool computeNumTriangles

If you want the class to compute a list containing the number of referenced triangles per vertex per vertex - pass true.

Fields

LiveTriangles

The table containing the number of referenced triangles per vertex.

Declaration
public uint32* LiveTriangles
Field Value
uint32

NumVertices

The total number of referenced vertices.

Declaration
public uint32 NumVertices

Methods

GetAdjacentTriangles(uint32 vertexIndex)

Gets all triangles adjacent to a vertex.

Declaration
public uint32* GetAdjacentTriangles(uint32 vertexIndex) const
Parameters
uint32 vertexIndex

The index of the vertex.
Returns
uint32

A pointer to the adjacency list.

GetNumTrianglesPtr(uint32 vertexIndex)

Gets the number of triangles that are referenced by a vertex. This function returns a reference that can be modified.

Declaration
public uint32 GetNumTrianglesPtr(uint32 vertexIndex) const
Parameters
uint32 vertexIndex

The index of the vertex.
Returns
uint32

The number of referenced triangles
