D3DXPLANE * D3DXPlaneTransform( D3DXPLANE *pOut, CONST D3DXPLANE *pP, CONST D3DXMATRIX *pM ); For the input plane parameter, the docs say: [in] Pointer to the input D3DXPLANE structure, which contains the plane that will be transformed. The vector (a,b,c) that describes the plane must be normalized before this function is called. See example. Why must the plane normal be normalized? I looked at the derivation of plane transformation in Lengyel's book, but it does not seem to require the plane normal to be unit length.
