This would make a great BORG cube!
Nice shade of green and soft corners!

I'm trying to figure out how radiosity
works so that I can get it right in more
complex scenes.

People are still deciphering radiosity? O.o

Here's a tip then: a higher count would make your scene look less splotchy.

(Cool pic, BTW.)

That's just plain cool!

So how have you made the edges bright green? Is that caused by the radiosity or
is it just a nice pigment? In either case I'd like to know how it was done
'cause it looks great.

After studying the picture I'm quite sure it's a pigment. Maybe Steven used
the same idea as H.E. Day a couple of years back ... faked metal w/ rough
edges.. He posted the code but I can't find it now (due to new search engine
on news.povray.org)

No, I actually used a union with a cube and
a superellipsoid. The cube barely emerges from
the superellipsoid that is almost a cube itself.

Wow, the change in colour at the edges looks much softer than I would expect.
The simple solutions are always the best :)

You mean you're amazed by how much this complex radiosity simulation looks like
a simplistic renderer from the 80's? ;)

 Speaking of which, does anyone here remember the Mind's Eye video?
I'm guessing so.  Anyways, there was a scene in there with a space station
like object, but the way it was rendered, it looked like it was filmed in
the 60s or something.  Anyways, I always thought it was cool how they
could make renders "look" old and wondered what it would take to make that
effect.  If nobody knows what I'm talking about, I could try to grab a
couple frames from that film and post them here.

I have no idea what you're talking about, so I'd definitely like to see the
images. But don't post them here since the admins don't like possibly
copyrighted material to appear on this server.

BTW, the "space station filmed in the 60s" I always think of is the one from
2001: A Space Odyssey, but that probably looks a lot better than the effect
you're talking about ;)

:-)

It's Tron-like, but no simple lines as in the original. It evokes the same
"feeling" of the original, while looking much more advanced and in par with
current technology. That's what I meant.

Also... sometimes beauty is in the simplest things. I like it simple. I
guess it's part of my "Zen" lifestyle. :-)

Roberto

A very beautiful picture. The intersections of the boxes look a little
muddy due to the lack of bright edges there. Bright green edges at the
intersections as well as the corners would look nice.

Well, as I recall, that "simplistic renderer" was a raytracer...but I 
agree, this looks much like my idea of a "modern" Tron.

As a neat side-note (well, I think it is neat), when they made Tron, 
they actually hand-coded the models into the computer and actually drew 
them by hand using coordinates they read off of print-outs. Imagine the 
patience it must have taken!!!

Also, the flickering you see is an accident. They got the film stock all 
mixed up in the store room. I got this stuff off the Tron DVD.

I'm not sure what you mean. The images come from a ray tracer. The models for
that were hand coded from hand-drawn diagrams with measurements, not the other
way around (AFAIK).

i.e. they did it the same way I do much of my pov stuff! Although I often don't
bother drawing it on paper first and just go straight into code.

It is a good DVD :) Though I haven't gone through all specual features yet so
you might know something I don't. :)

It is still the best way to do it, IMHO. You aren't limited by some 
programmer's idea of a GUI.

Thought so. Although a lot of the effects were actually hand drawn (the frisbee,
most of the static backgrounds). But the 3D stuff was all ray traced.

Well these days most of the professional packages have a user interface mostly
designed by people who use it, because the evolution of the GUI has been gradual
over many years based on feedback from users and competition from other
packages. The problem is that this isn't true of free software, so personally I
think pov's the best option.

But Wings3D is cool too :)

Anyway, we've got way off topic so I'm gonna shut up now.
