One flaw with this technique can be seen in the image:
http://www.brickshelf.com/cgi-bin/gallery.cgi?i=9233
Observe the sides of bricks which are seen almost
edge-on (so that the distance to the object from
pixel to pixel is large even for the same surface).
In particular, the front of the white brick at the
front of the space ship. It is completely black, I think
because it triggers the edge-detection algorithm.
My rayshade patch (mentioned elsewhere) detected edges by
looking for multiple objects within one pixel. The problem
with it was it would create edges even when two polygons
were flush against each other (like how the top of an LDRAW
stud is made of many triangles). A combination of the
techniques, where the edge is suppressed if the object is the
same, would fix the blacked-out-surfaces seen in the image.
