Thanks :)

Well, that one seems a bit more complex (and cooler) than mine to me. :)

The image you see took about 6 hours, but a version with 640x480 and
acceptable quality rendered within an hour. Athlon XP 1400 mhz. Sure it is
nice to have a powerful CPU.

It's a blobed blob :) I can post the source if you are interested, but it's
just a blob with a sphere and 3 negative cylinders along each axis. I first
tried CSG but I found out that the simplest approach is to do it with the
blob object.
I also have an animation of the photon caustics without the object, the
quality is ok (it seems artefacts are impossible to get rid of entirely
though), and povray split out a 640x480 frame in 6 mins :) All common codecs
(mpeg1, mpeg2, divx, indeo) seem to totally mess it up though :(
I'm still new to photons, so it would be great if someone would help me
optimize my settings after I posted the source. I also find that the AA is
less than perfect (look at the top of the object and some of the sharper
lines of photon highlights for exapmle). Is this a limitation of povray or
am I missing something? My settings were:
threshold 0.05
depth 3
method 1
Oops I'm a bit too talkative this night (morning) I guess.
Gergely
PS: should photon jitter be avoided in animations? Is it the same kind of
random noise as in AA and media?

Source can be found in p.b.s-f now.

It's my new desktop picture...
Could you post the source, so I could render it at a higher resolution?

Already posted on p.b.s-f. (subject: glass blob with photons)

I don't know but for the still image I think you could have used a higher
jitter for the photons, there are some features in the caustics that
shouldn't be there, IMHO.
btw, I think it would look even better with dispersion (but beware of the
brightness bug...and the rendertime)

Eerie. I did an almost identical image about a month ago.

Well, I agree, looks really nice. Almost photorealistic.
ALMOST, because the large white spot without much gradient to it (where
the
lightsource is) is just a little too big for photos... ;)

Don't have that one anymore, but I have a few others I made messing around
with photon and light settings from Lance Birch. I will pick out the best
one and post it. Mine didn't turn out quite as nice as yours. The shape and
material were almost identical, but my light placement made less impressive
photons. I may try and re-write my version from what I have left of the
scene.
