ID3DXMesh::GenerateAdjacency Method

Generates adjacency information based on mesh indices.

Syntax

HRESULT GenerateAdjacency(      

    FLOAT fEpsilon,
    DWORD* pAdjacency
);

Parameters

fEpsilon

[in] Specifies that vertices that differ in position by less than epsilon should be treated as coincident.

pAdjacency

[in] Pointer to an array of three DWORDs per face to be filled with adjacent face indices. 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.
