Awesome. I am impressed.

One fun thing would be to take some demo images from some famous packages,
redo them in Povray and bundle the code with 3.5. I'm not sure about
possible legal problems but still...

That would surely be interesting, but on the other hand, each program
tries to show it's strength in such scenes and at the same time tries to
avoid the weak points. Copying such demo scenes would therefore show the
ability to do the same things as another program, but would not show one
of the main advantages of Povray, namely to handle a very large variety of
different effects.

Thanks Ron, for your reply.
I'm sorry, I didn't mean to blame and I understand your arguments. But I
was disappointed by what seems like unnecessary competition. I have the
greatest respect for the POV authors. I didn't mean THEY should have
implemented the formulas in the first place. The author of Lightflow
COULD have done it however, since his product seems like a POV concept.
And we don't need incompatible programs. POV is already established and
well known.

Great, Warp! This is indeed very nice! I doubted this was possible.
The pictures I referred to as being better, well, were mostly the glassy
versions found on the lightflow homepage, buuut.. Hmm now I dare believe
they can be done in POV with the exsisting formulas.. I am surprised.
Hmmm. What a day.

Yeah, so, add those scene files as well. POV should come with scene files
that show EVERY area that POV excels.. including those that other progs
excel at too.
After all, that's one of the beauties of text scene files, they can take up
so little space, especially when compressed in the prog distribution.
I'd like the distro to have many more scene files, perhaps donated by users.
Obviously, POV 3.5 would have to be out for a while before people could code
scenes for it, but there'll no doubt be program updates, and they could be
included there.

as you have demonstrated, POV is an excellent tool, it just takes a little
understanding :)
reminds me of the Arnold images, everybody went wow, and days later we were
all doing the same with pov ..

How about this: Take each of those scenes and add something that couldn't be
done with those programs into those scenes.
