ID3DXPRTBuffer::ExtractToMesh

Extracts coefficient data from a single-channel buffer and adds the data to an ID3DXMesh object.

HRESULT ExtractToMesh(
  UINT NumCoefficients,
  D3DDECLUSAGE Usage,
  UINT UsageIndexStart,
  LPD3DXMESH pScene
);

Parameters

NumCoefficients

[in] Number of coefficients to extract from the buffer. When using spherical harmonic (SH) precomputed radiance transfer (PRT), the number of coefficients should be Order ². Order must be in the range of D3DXSH_MINORDER to D3DXSH_MAXORDER, inclusive.

Usage

[in] Vertex usage descriptions of the mesh. See D3DDECLUSAGE.

UsageIndexStart

[in] Starting index for coefficients to be stored in the mesh.

pScene

[in] Pointer to an ID3DXMesh mesh object that will store coefficients.

Return Values

If the method succeeds, the return value is S_OK. If the method fails, the return value can be one of the following: D3DERR_INVALIDCALL, E_OUTOFMEMORY.
