MegaPOV has an angle of incidence pattern which creates this effect 
quite nicely. A color_map where the faces pointing towards the camera 
are transparent, and the angles facing to the side are opaque, will do 
the job.

You can also do this with the official version of POV, with the "slope" 
pattern. The results will not be accurate, however, unless you use an 
orthographic camera.
