## Member Function Documentation

template<typename T>

void CS::TriangleIndicesStream< T >::BeginTriangulate | ( | const uint8 * | index,
|  | const uint8 * | indexEnd,
|  | size_t | stride,
|  | csRenderBufferComponentType | compType,
|  | csRenderMeshType | meshtype |
| ) |  |  | `[inline]`

Begin triangulation of an index buffer.

Parameters:

  | index | Pointer to start of the indices.
  | indexEnd | Pointer to end of the indices.
  | stride | Distance between index elements in bytes.
  | meshtype | Mesh type of the index data.
