It is much easier than that. POV only cares about the extents of the 
shape (which are already calculated), and where it intersects along a 
ray...how the shape comes up with those values is the shape's business. 
You don't have to create a bunch of cylinder/cone objects, all you have 
to do is change the intersection code. The hard part is coming up with 
an algorithm to determine the intersection...the existing sphere sweep 
code might be the fastest way to do that short of generating a mesh.
