I'm admitting that I'm way over my head in this discussion, so I won't be 
offended if you inform me that I'm not making any sense. ;-)

To move forward a little and to generalize a little, one of the benefits of 
POV-Ray is the fact that it uses function based surfaces (CSG), rather than 
meshes.  i.e. A sphere is a sphere, not a bunch of triangles glued together 
with normal interpolation.  Imagine placing a sphere inside a slightly 
larger mesh-based sphere.  You'd see the smaller sphere poking through the 
mesh in some places, even though the mesh-based sphere would actually appear 
larger (this could be a neat illusion).  In the long-run, wouldn't it make 
more sense to actually create function based, spline-type surfaces?  Is that 
what NURBS are?  (If so, then this has probably been discussed before.)

Before you kill me, realize that I'm just making statements based on 
something that I know very little about and would have almost no idea how to 
implement, so be nice.  ;-)

Oh, also I've apparently been saying "smooth triangle problem" when I should 
have really been saying "shadow line problem".  I assumed they were both the 
same thing.
