Retrieves the index of the bone influence affecting a single vertex.

HRESULT FindBoneVertexInfluenceIndex(
  DWORD boneNum,
  DWORD vertexNum,
  DWORD * pInfluenceIndex
);

Parameters

boneNum

[in] Index of the bone. Must be between 0 and the number of bones.

vertexNum

[in] Index of the vertex for which the bone influence is to be found. Must be between 0 and the number of vertices in the mesh.

pInfluenceIndex

[in, out] Pointer to the index of the bone influence that affects vertexNum.

Return Values

If the method succeeds, the return value is S_OK. If the specified bone does not influence the given vertex, S_FALSE is returned. If the method fails, the return value can be D3DERR_INVALIDCALL.
