POV-Ray does it for /height fields/, but those are totally different 
animals. Normal computations for height fields are not performed in the 
"mesh domain" (in fact height fields are not even represented as meshes 
internally), but in the "image domain" (based on the value differences 
between adjacent pixels), which obviously is impossible to apply to meshes.
