ID3DXPRTEngine::ScaleMeshChunk

Scales all the samples associated with a given submesh. The method is useful for computing subsurface scattering.

HRESULT ScaleMeshChunk(
  UINT uMeshChunk,
  FLOAT fScale,
  LPD3DXPRTBUFFER pDataOut
);

Parameters

uMeshChunk

[in] Location in the mesh at which to start scaling samples.

fScale

[in] Value by which to multiply each vector in the submesh.

pDataOut

[in, out] Pointer to a ID3DXPRTBuffer object to receive rescaled samples in the submesh.

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.
