A quick preview render of a diamond. Major change: conserve_energy added to
prevent it becoming too bright.
Forgot to turn on aa but I don't want to wait for another render. I've
uploaded the scene if anyone has cpu to spare on the hq version.
Some stats:
Max level 11/11
Number of photons shot: 1700488
Number of photons stored: 16787408
Priority queue insert: 74077406
Priority queue remove: 31574428
Gather function called: 796316
Gather radius expanded: 426477
Peak memory used: 336070926
Time For parse: 0 hours 0 minutes 8.0 seconds (8 seconds)
Time For Photon: 7 hours 33 minutes 51.0 seconds (27231 seconds)
Time For Trace: 1 hours 6 minutes 53.0 seconds (4013 seconds)
Total Time: 8 hours 40 minutes 52.0 seconds (31252 seconds)

Much better! It looks very real. Now if only I can model that ring...

Wow! This looks real! And very nice too!
Brilliant!

Nice diamond... :-)
7 and a half hours just for the photon calculations though?! And there's not
much of them to see either. I'll have to get your file and have a look for
myself but seems to be the extravagant amount of memory it used. Must've been
swapping to disk a lot if you had 256MB RAM or less, which is all I have.

Really nice!!
Are you sure you need this big amount of photon 1,700,000!!
Very big no?
Fabian.

Thank you everyone!

Hm. Very probably overkill. I did that to get sharp edges on the reflective
caustics. The diamond is appr. 2 units wide and to get a decent photon
resolution on the surface I thought spacing 0.02 would be nice. In the scene
I uploaded I used spacing 0.01 which is very very probably overkill :)
Suggestion for photons: what if you could set refractive and reflective
spacing independently? I don't need all those photons for refraction but
from what I've tried here I seem to need'em for reflection.

Various optimizations left me with this one. Much nicer photon settings, but
a tad blurry reflection :|

You're getting a maximum of 10 ray intersections (if I'm wording that right)
and using 120? Interesting.... Not necessary to do so then.
It looks great so far. Thought about using area lights yet? <ducking for
cover>

Additional photons are stored for deeper trace levels. When refraction
and reflection are involved, you get much more rays than you've asked
for ;)

I just picked a fairly big number and counted on adc bailout. I don't know why
I got only 10 though. For this render I used fade_power 1000 fade_distance 150
so I expected to see much more ray traces.

BOOM! <catchiiing>
Damn, I missed.

I thought about it. Maybe what we can do is once we are all happy with the
diamond, we can setup an area light then whoever is interested can render a
piece of it. The majority of the time will be spent on the render, not the
pre-processing, so the parallelism should save us some time. We could also
be daring and attempt to have more than one diamond. :)
I have two computers at work that can render overnight.

On somewhat the same subject: anyone ever pass around a saved photon map
before? Just curious if that's easy to do, and not only that if there would
be unforeseen problems from one computer to the next.

Ever see the size of those suckers? The last one I did for the diamond was
137MB (about 4 million photons if I remember correctly), although I'm sure
they compress well and it might be worth the time saving if you have a fast
enough connection.

The photon map file from my "Teardrop Prism" image was 220 MB.

You people use far too many photons. j/k! Mine always seem to remain at or
below a million. But then I have yet to do a terrific scene with them either.
