Hmmm, are you being sincere Ken, or was that ment to be sarcastic?  :)

I can truthfully say I much prefer it over a mirrored ball
floating over a checkered plain ;^ }

You give good torus.

Sincerly,

sPatch - as its name suggests - is written for generating objects that are
made out of (bicubic) patches. And in my opinion it does a great job in
doing this.

A bicubic patch is also a POV-Ray primitive. However, memory and time 
consumption for rendering is significantly higher if you model a cube by 
six bicubic patches than by the primitive "box". However, bicubic patches 
are a must for modelling organic-like shapes.

Converting bicubic patches to CSG is a non-trivial task and in most cases
impossible. That's why you should use CSG where appropriate and bicubic
patches where needed. Personally, I use hand-written POV-Ray files and
include some objects that were generated by sPatch. As others suggested
you may use other modellers for the CSG part.

Happy tracing

Thomas
