Drat! I'm sorry I did not mean to be rude to you. I did not realise that you
were one of the hosts. Put it down to my age and being a Brit. I still stand by
my opinion about the way people speak but I apologise to you for being
personally rude.

I think it's because I had just seen "The Big Lebowski" on cable, where "dude"
is said about 100 times, including the catchphrase "the dude, abides".

I'm surprised you keep saying "they" when you're talking to me. :)

I think that's a huge understatement, dude :p

great show btw!

Aren't we all kids at heart deep down :) Yea verily and as nemesis pointed out
Americans doth speake thus. ;-)

That is because I knew not that it was you. And yes I am a native English
speaker who sympathises with the French trying to eradicate Franglaise :)
I'm also a Radio 4 listener (BBC) and that should explain a lot :)
Again I'm sorry if I offended you I thought that it diminished David and Chris
and I'm a bit protective. I was also offended when Mr Bush was heard to greet Mr
Blair (not Prime Minister Blair, which is not what he is called) by Ho! Blair.

I always watched Leo LaPorte on TechTV years ago. Took me some getting used to
at first. Kept thinking he was stepping indoors from a California beach every
time. ;) I think he must have had a frisbee made from a laser video disc
someplace. :D Liked that show, and the others. Erica Hill doing CNN now, very
sad when James Kim and family got lost in the mountains a while ago.

This was a fun listen, so my immense thanks for doing this interview and posting
about it here (whomever did, I'm replying to the end of the web view).

The topic of physical reality (of light) was only touched upon near the end.
That could have been interesting. Leo asked something about the possibility of
doing a spectrum in a prism after David and Chris left the talk.
There's a whole subject about recreating true characteristics of light and
reflection that was only hinted at. Most of the talk concerned artistic merits
of POV, or the coding changes; obvious why that was. :)

I'm in complete agreement about the awe-inspiring abilities people have to get
both programming and art together. It fascinates me whenever I see any of it,
new or old stuff. I think it's something overlooked in other CGI related
things. You can't really miss that point about POV-Ray.

Thank you again. I've been getting farther from the goings-on here in recent
years so this was great.

That was me.  I was wondering if you can get chromatic aberration
with POVRay, and Leo insisted that you could (without knowing),
and I regretted not asking while Chris and David were on the podcast.

So what is the answer?  Can you make a Prism that works, breaking
white light into a rainbow?

    [Mars was] mineral; not animal, nor vegetable, nor viral. It could 
have happened but it didn't. There was never any spontaneous generation 
out of the clays or the sulphuric hot springs; no spore falling out of 
space, no touch of a god; whatever starts life (for we do not know), it 
did not happen on Mars. Mars rolled, proof of the otherness of the 
world, of its stony vitality.
    And then, one day...

Actually, rereading that page, I think that's a picture with several 
colored light sources, not an image with working chromatic aberration. :-/

But yes, Povray supports that.

Running "beautifully fast" on modern hardware is somewhere between "I've 
never been to jail" and "I shower daily" on the list of human 
accomplishment.

it's called chromatic dispersion in POV-Ray:

There's two different effects, both called "dispersion" in POVRay. 
There's the one that makes the pretty patterns in the shadows of sparkly 
things (using photon mapping) and there's the one that causes the 
"chromatic aberration" problem that plagues telescope makers.

I suppose that in the real world they're both caused by the same 
fundamental physics, but in POVRay the settings for enabling the effect 
in the forward mapping of photons is separate from the settings for 
enabling the effect in the conventional tracing of rays.


I vaguely seem to remember that the documentation for DKBTrace claimed 
that chromatic aberration was "a bug in the real world" and was 
therefore not then supported.
