D3DXCleanMesh Function

Cleans a mesh, preparing it for simplification.

Syntax

HRESULT D3DXCleanMesh(      

    LPD3DXMESH pMeshIn,
    const DWORD *pAdjacencyIn,
    LPD3DXMESH *ppMeshOut,
    DWORD *pAdjacencyOut,
    LPD3DXBUFFER *ppErrorsAndWarnings
);

Parameters

pMeshIn

[in] Pointer to an ID3DXMesh interface, representing the mesh to be cleaned.

pAdjacencyIn

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

ppMeshOut

[out] Address of a pointer to an ID3DXMesh interface, representing the returned cleaned mesh. The same mesh is returned that was passed in if no cleaning was necessary.

pAdjacencyOut

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

ppErrorsAndWarnings

[out] Returns a buffer containing a string of errors and warnings, which explain the problems found in the mesh.

Return Value

If the function succeeds, the return value is D3D_OK.

If the function 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.

Remarks

This method cleans the mesh by adding another vertex where two fans of triangles share the same vertex.
