Thank you very much Hugo !

The NURBS math may look somewhat scary at a
first glance, but if you work through each of the
necessary math steps, then you'll see that each step
isn't that big. Just remember to test and experiment
with POV as you go.

I frequently do such POV-tests along the way when
reading about new stuff. In that way I'm able to
verify that I've understood it right.

Note that in order to optimize the declarations of the
functions, my code makes some of the expressions
look very obfuscated.

If there's anything in my code that you have specific
questions about, then feel free to ask. (But I cannot
promise you quick answers.)

And: I will be happy to see yours and others NURBS
experiments !


Tor Olav
