(...) That's is the (Odd/Even) test, also with Raycasting, but no supersampling, in the supersampling case, you just subdivide the polys further and further, or shoot pseudo-random rays until you find the correct normals for all faces. this does NOT (...) (25 years ago, 5-Apr-00, to lugnet.cad.dev)

(...) Perhaps this approach is a bit naive, but couldn't you use something similar to a point in polygon test? Cast a ray along the normal from the center of each polygon. If it intersects an odd number of surfaces then the normal points toward the (...) (25 years ago, 5-Apr-00, to lugnet.cad.dev)
