I have also written a bezier macro that makes 3d splines. It can handle joining
splines together and there is a simple trick to
making the timing work out. I can send it to you, but I'm afraid I haven't finished
the documentation for it.

Well, would a kid in Pre-Calculus be able to understand it if he tried hard enough?

You should be able to. I'm only in Calculus myself. I have a lot of Math to catch up
on. I'll forward it to you.

Both of you are lucky, I am stuck with Algebra II(which is way below my 
level of ability).
However, I have been looking around for some good Trig/Calculus books, 
any suggestions? On second thought, better post replies to this message 
to povray.off-topic. :-)

    I have seen some of the other responses.

    No. If you do not understand it, you find and follow the recipe. If that does not
work you find the theory and learn it. That is
the only solution.

    I have more math behind me than I would like to be reminded of. I'd find the right
equation, render about three to six errors
before figuring out how to make it run right. It would also take me about ten times
longer to relearn the math and then try to make
it run right so I don't bother. So I live on the gut feel memory.

    Sorry but there is no substitution for you time in hell learning the math.

    But the good side is that you can fake camera location and look_at and probably
get it right in the same six errors tries that it
takes me.

    If you do not understand the basic representation of the math then you have a
problem that only education will repair. It is not
hard really. Rather it is more like learning the language. Its nothing secret, not
magic, just a language. Once you learn to think in
it you are home free.

I got your forward, thanks!  Haven't had time to look at it yet... been kind of busy.

Oh, that's great, thank you.  That really helps.  The include file is good, and I made
another similar one that better suits my
purposes.  Thanks a lot!

Great! I hope you'll share what you did

You're not wrong there. Better still, the more effort you put into
using Chris's stuff, the better the result (exponentially, or so it
seems).

A complete novice (like me whan I started using his include files) can
produce a picture using his tools which make audiences go "wow". Put
twice the effort in and IMO you get 4 times the result from his stuff
- much like POV itself I guess.

Sorry about the slavering. Long time Chris Colefax fan :)
