Read the message I was responding too...it talked about solving it 
numerically. Actually, read my message: I made it quite clear what I was 
saying. Using pyramid tracing may be possible in theory, but would make 
things impractically difficult and would have almost zero quality 
benefit, since most things would have to be broken down and solved 
numerically anyway, and a big impact on rendering speed.
