Sets an albedo value for each texel, overwriting previous albedo values.
Syntax
HRESULT SetPerTexelAlbedo(
LPDIRECT3DTEXTURE9 pAlbedoTexture, UINT NumChannels, LPD3DXTEXTUREGUTTERHELPER pGH );
Parameters
- pAlbedoTexture
- [in] Pointer to an IDirect3DTexture9 texture object in which to store albedo values.
- 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.
- pGH
- [in] Optional pointer to an ID3DXTextureGutterHelper object. If not provided, a texture gutter helper object is created and destroyed internally.
Return Value
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 The method call is invalid. For example, a method's parameter may have an invalid value. D3DERR_NOTAVAILABLE This device does not support the queried technique. D3DERR_OUTOFVIDEOMEMORY Direct3D does not have enough display memory to perform the operation. D3DERR_WASSTILLDRAWING The previous blit operation that is transferring information to or from this surface is incomplete. E_OUTOFMEMORY Direct3D could not allocate sufficient memory to complete the call.
