ID3DXMesh::ConvertPointRepsToAdjacency Method

Converts point representative data to mesh adjacency information.

Syntax

HRESULT ConvertPointRepsToAdjacency(      

    CONST DWORD* pPRep,
    DWORD* pAdjacency
);

Parameters

pPRep

[in] Pointer to an array of one DWORD per vertex of the mesh that contains point representative data. This parameter is optional. Supplying a NULL value will cause this parameter to be interpreted as an "identity" array.

pAdjacency

[in, out] Pointer to an array of three DWORDs per face that specify the three neighbors for each face in the mesh. The number of bytes in this array must be at least 3 * ID3DXBaseMesh::GetNumFaces * sizeof(DWORD).

Return Value

If the method succeeds, the return value is D3D_OK.

If the method fails, the return value can be one of the following values.

D3DERR_INVALIDCALL	The method call is invalid. For example, a method's parameter may have an invalid value.
E_OUTOFMEMORY	Microsoft?Direct3D?could not allocate sufficient memory to complete the call.
