Hi all,

Was trying to explain to Stephen how I was using spheres to light a scene -
my description was a little unclear so I'm just posting an animation I have
with the effect in question.

Before anyone says it: I know the glass block looks weird at the base - I'm
guessing it's as the block exactly ends where the table starts - I moved on
to another scene before fixing this.

Oh and sorry it loops 2(?) times, I don't have the stills any more - just an
800x600 video which I've resized to post here so it's all a bit of a hack -
I've tried to reduce the size as much as possible and still have it
watchable.

All that aside, as always, any comments greatly appreciated.

(I'm sure everyone else has already done this but I'm still learning :D )

Regards,
Simon

that looks very nice
in fact the lighting is so real it lets you forget about the scene only
beeing simple csg

Where's the original discussion?

This is very nice.

You know you've been raytracing too long when you see the movie credits 
going by and instead of seeing Lenses by Panaflex it always seems to say 
Lens Effects by Chris Colefax.

Original is in newusers - titled "transparent objects"

Thanks for the positive feedback!

Ah, somehow my newsreader pulled in this thread before the original 
thread. Go figure. :-P

You know you've been raytracing too long when you can describe in 
perfect, legal, pov syntax, how to re-create everything in your computer 
room using primitives and csg operations.

Thanks :)

Don't forget I'm a newbie so simple CSG is about my limit right now. :D

For the record it takes a VERY long time to render - That animation 
(800x600x500frames) took around 2 1/2 days (I actually left it rendering and 
went on holiday to Spain).

Can't wait until V. 3.7 which can handle multiple processors which should 
almost halve my render times.

Very effective use of CSG. :-) Good job!

What hardware are you on?

In a pinch, when you're doing animation, there are ways to make Pov only 
render half of the frames. You could try running a separate copy of Pov 
at the same time on the other half. Cumbersome, though. :-P

You know you've been raytracing too long when you downloaded and printed 
the Renderman Interface documentation, so you'd have a little light 
reading to take on holiday.

That's what I had working at one point but I found it to be a complete pain 
in the backside and with the exception of using radiance, more time to set 
up than to just wait...

I've got the pentium Core2Duo E6900 which is VERY shiny but only a Gig of 
ram so need to do a bit of an upgrade there at some point. For gaming, I 
have a GeForce 7600GT - Also needs an overhaul as soon as DX10 cards are 
out. and 2x240GB SATA-2 HDDs. All in all, a fairly nice PC (and it has a 
blue neon light on the front :D )

I did find a program that would handle networked rendering and multiple CPUs 
but it was slightly buggy and involved launching lots of instances of POVRay

What OS? Under Linux at least, I could think of some fairly easy ways of 
automating that.

Also, there was an SMP patch for 3.5--it might be worth temporarily 
downgrading for that. :-)

Hmm... you're making me jealous. :-P

Those programs try to do waaay more than what you need for harnessing a 
dual-core box.

You know you've been raytracing too long when you've tried rendering 
hair with each strand as an object.

For my sins, I'm running XP as a LOT of the work I do requires windows (My 
company develops software for windows as well as ASP pages served from IIS). 
Also, the radmin software they have to punch a hole through the company 
firewall is windows only. I have a second box running smoothwall as a 
firewall (really low specs) and I've just installed Fedora on my old windows 
box (somewhere in the middle Spec-wise - an AMD athlon X64) but XP is def. 
the workhorse at the moment

i'll have to look into that!

> Hmm... you're making me jealous. :-P

It is shiny :D

I fully agree. Not to mention the fact that it was using flat-files for a DB 
and using windows shared folders rather than TCP/IP or similar.
