Where are the checks? :)
No fancy tricks here, but I still like it.
Comments, suggestions, etc. welcome.
Cheers,

Wow !
- Nice image.
This seems to be a shape that is quite similar to
the one I made in late January 2001: "Outside It"
http://news.povray.org/povray.binaries.images/13533/91167/
news://news.povray.org/3a7eed3a%40news.povray.org
I have always wanted to see such a shape rendered
in glass with a high enough max_trace_level and
photons, but I never had a powerful enough computer
to do it.
How long time did it take to render ?
And is this shape made with CSG ?
Or as a "blobbed" iso-surface ?

Great image, very beautiful.
Will you share the source?, I'm interested in the photon part.
Bye

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... ;)
