Sets texel barycentric coordinates.
HRESULT SetBaryMap( D3DXVECTOR2 * pBaryData );
If the method succeeds, the return value is S_OK. If the method fails, the following value will be returned.
D3DERR_INVALIDCALLThe third barycentric coordinate is given by:
1 - ( pBaryData.x + pBaryData.y )
The barycentric coordinates input to this method are valid only for valid (non-class 0) texels. ID3DXTextureGutterHelper::GetGutterMap will return non-zero values for valid texels.
Barycentric coordinates define a point inside a triangle in terms of the triangle's vertices. For a more in-depth description of barycentric coordinates, see Mathworld's Barycentric Coordinates Description.
