ID3DXMesh::OptimizeInplace

Controls the reordering of mesh faces and vertices to optimize performance.

HRESULT OptimizeInplace(
  DWORD Flags,
  CONST DWORD* pAdjacencyIn,
  DWORD* pAdjacencyOut,
  DWORD* pFaceRemap,
  LPD3DXBUFFER* ppVertexRemap
);

Parameters

Flags

[in] A combination of one or more flags from the D3DXMESHOPT enumeration, specifying the type of optimization to perform.

pAdjacencyIn

[in] Pointer to an array of three DWORDs per face that specify the three neighbors for each face in the source mesh.

pAdjacencyOut

[out] Pointer to a destination buffer for the face adjacency array of the optimized mesh. The face adjacency is stored as an array of arrays. The innermost array is three indices of adjacent triangles, and the outer array is one set of face adjacency per triangle in the mesh.

pFaceRemap

[out] Pointer to a destination buffer containing the new index for each face.

ppVertexRemap

[out] Address of a pointer to an ID3DXBuffer interface; containing the new index for each vertex.

Return Values

If the method succeeds, the return value is D3D_OK.

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

Notes  This method will fail if the mesh is sharing its vertex buffer with another mesh, unless the D3DXMESHOPT_IGNOREVERTS flag is set in the Flags parameter.

Requirements
