ID3DXPRTEngine::SetPerVertexAlbedo

Sets an albedo value for each mesh vertex, overwriting previous albedo values.

HRESULT SetPerVertexAlbedo(
  CONST VOID * pDataIn,
  UINT NumChannels,
  UINT Stride
);

Parameters

pDataIn

[in] Pointer to FLOAT albedo data of the first sample.

NumChannels

[in] Number of color channels to set. Set to 1 to specify gray materials (R = G = B), or 3 to enable color bleeding effects.

Stride

[in] Stride in bytes needed to get to next sample's albedo value. See Width vs. Pitch.

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.

Requirements
