The extra utilities and .inc files are merely helpful. You do not need
them to start raytracing.

I'm not sure, as I do not use Moray or Texture Magic.

Ah, another user brainwashed by M$. <shaking my head>

Your best bet is to get Dta. This utility will let you make your tga
frames into a fli animation file. I think it's available at the povray
homepage (www.povray.org) under utilities.

You dishonour me sir! I challenge you to a duel; reflective spheres over
checkered planes at 50 paces!

And to think all this time I thought 'reflective spheres over
checkered planes' was the POV equivalent of the Catholic
Hail Mary...

Ahem.

My newsreader tends to jump around more or less randomly when opening a
newsgroup; as a result, I sometimes find myself trying to carry on
conversations which finished months or, as in this case, years ago. By
now this guy has probably won IRTC 3 times.
Ho hum. In future, I'm going to learn to check the date on posts before
replying to them. Still, it encouraged me to try a few new takes on
RSOCP, so it's not all bad...

Thanks. I was experimenting with my latest macro, which generates a
sphere from a set of hyperbolic non-cartesian splines. The results still
leave a little to be desired, but I'm working on it. The plane uses a
macro I wrote a while back, which averages several 3-d trigonometric
waves to approximate an infinite, flat surface.
What looks like a sky_sphere is in fact an infinitely large polynomial
surface defined in Hilbert-space; one of my first experiments with
isosurfaces. I quite like it.

Oh, that sounds very interesting. Can we see the source, please?

You know I was making all that up, right? Seriously, this one *is* made
from an isosurface, and I've included the source to prove it.

Of course :-)

To be honest I had to look at the Isosurface manual to find out, what a
strophoid is. Not bad, as this one is a bit differed reflective sphere over
checkered floor. Just reports 1 object, 0 infinitives in the stats, doesn't
it?

Anyone willing to beat that?

well that proves that I need to read the docs some more, I believed you :-)

boy do I feel stupid.
