Hello,
I haven't posted anything for a while, because I have been doing a render
that took overall around 4.5 weeks! Now, I had Unreal running at the
weekends, but during the week Pov was the only thing running. I was just
originally a test in Rhino to merge a wandle into a jug body, but I thought
I would test Photon's with it. I must have gone overboard in the settings. I
can't give a definite time for render, as it was stopped and continued may
times, and there is a bug in the Windows version where the trace time
doesn't stop when the render is paused. I think is looks nice in black and
white, so I have included a post processed version as well. Originally
rendered in 1280x1024.

Despite the large download size, I had to see what took 4.5 weeks. Very
nice. I would like to see something done with the plane it's sitting on.
The nothingness in the background looks kinda funny, too. Everything else
could pass for a photo.

That's some extreme detail in your caustics. What was the total photon
count?

Wow, I should take the comment about glass out of my reply to Andre's "More
Alcohol" posting and put it here instead. In case it's not seen I basically
said glass textures are both a good and bad thing, for obvious reasons.
The B&W version is actually sepia and not all gray shades I see. Has a good
look to it.
That purple pitcher has too soft a highlight IMO, hate to say it because of the
tremendously long render time you endured.
Any plans to try a speeded up, less photon-intensive, version or has it already
been done?

Sorry, but the purple glass needs a tighter highlight and there's some banding
in the shadows. Try for a ten-week render. ;-)
wow

I like the softer highlights on the purple jug. I got some glass just like
it but its got a rough surface texture.

Isnt it amazing that POV takes 4.5 weeks to render this but nature could render
it instantly. :)
Very nice image, caustics are impressive.

Wow! Both the coloured and black & white versions are
fantastic, I love things like this.
This reminds me that I need to read about the changes
to photons in 0.4, as I've tried a render and found
they're totally different to 0.3.
If you rerender this try a slightly wider camera
angle, just that glass on the right seems to be
leaning over a bit.

Hmmm... there's an idea - would there be any way to get Povray to trace more

I had an infinite plane in before hand, and that didn't look so weird, but I
was re-reading the photon documentation and I noticed that it says photon's
work slowly with infinite plances, so I changed it to a thin box. Also, I
though just leaving the surrounding area black would help to make the
caustics seem brighter (just relatively).
I think I need to study photons a bit more, and find less intensive settings
:)

Sorry Nathan, as soon as the trace was finished, I upgraded to Megapov 0.4,
and traced all the demo scenes, so the stats have been cleared out of the
history. I can however tell you that calculating the photons took around 25
minutes on my P2 450 with 128mb of ram, so I saved the photons to a .ph
file, and the file's size is 30.6 megs.

I am begining to agree :)

I know, I thought it might help the photo look a little, plus I'm a fan of
sepia tinted grayscale images.

Oh no worries. I was going for a frosted kind of plasticy (is that even a
real word?) look.

Maybe. I really need to learn exactly what each of the settings do, so I can
balance quality with time. Though I am wondering what caused the long render
time for my image. The jug, water and glass meshes have thousands and
thousands of smooth triangles - could that be what took all the time, or was
it just that I went overboard on my settings? In global settings I used :
photons{
gather 20, 100
radius 0.1*phd, 2, 2//, 0.1*phd
autostop 0
jitter .4
expand_thresholds 0.2, 40
load_file "jugwaterglass.ph"
}
and then for the objects I used:
photons {
separation 0.02*phd
refraction on
ignore_photons
}
except for the two glasses which had reflective photons also.

Hi,
Thanks. That's basically what I was going for. I have some glass marbles
here that are made of frosted glass, and I though "I'm going to try that!".
I went for a frosted plastic look though in the end, to make a change from
the two glasses.

Hi,
Speaking of animation, before I realised how long the render was going to
take, I was considering doing an animation with photons. There is a physics
simulation program out there somewhere, can't remember the name right now,
that uses simple primitives in the simulation. So I was thinking of building
a simple jug, filling it with thousands of tiny spheres and then pouring
them into a simple glass. Then for the final animation, I would change the
spheres into spherical blob components, with the hope that they would blob
togethere to create realistic flowing water.
But I'm not going to do that now ;)

Hi,

Thanks. I was partially inspired by the still life rendering on the front
page of the Radiance site.

I know, I've just noticed now. Hopefully this will make it easier though.

I think the glass is leaning because I used too wide a camera angle. I think
it was somewhere near 70 degrees or something. The camera is fairly close to
the objects as well, which doesn;t help.

No doubt the refraction and reflection eating into the render time. You didn't
say what 'phd' was equal to but I suppose 1.
I was thinking when I first saw the pitcher that it might be non-smooth glass or
plastic but the clear refractions don't prove that out. A good candidate for
Chris Huff's transparency blurring patch.
All in all it seems the makings of a year long project if everything you say
were to be done, either that or render farm comes to mind, heh-heh.

On less than two processors, no. If a processor is designed a
particular way, it is possible for it to trace two rays at once, but it
would be far more trouble than it's worth; the rendering engive would
almost certainly have to be rewritten directly in assembler, and I doubt
the POV team is interested in doing that.

John

Quantuum-processors would reduce the rendering-time tremendously. Not only
would they be fast, but they calculate implicit equations instantly, just
like optimal angles between atoms in molecules are found instantly with
quantuum-porcesses. Ray-object intersections could be calculated instatly
for _any_ surface. Now _that_ would be something.
I've heard that they now have constructed a simple quantuum-ciruit that does
some simple calculations. Int the future ... blabla.
Simen.

No, nature's render time is however long it takes the light to get from the source
to the destination. Now if you factor in the miniscule, unnoticable effects of
distant stars, nature took billions of years to render it! :-)

One of my ambitions is to be able to open up a yuppie store where you
have to throw your wallet in the door first, and if there's enough money
or credit cards you can come in and spend it... The kind of store that

The One and ONLY QUantum computer takes up an entire lab of MIT (I think) and
can only process only one program as of October of 1999 (it answers a series of
simple questions...) there was an article on it in Discovery magazine a few
months back... try looking it up in the library cause i may be wrong on the
Location, size and program types..... but It is supposed to be at least 1000
times faster than the standard supercomputer ( is there really such a thing as
standard supercomputers?????? ).

So then we don't know how much time the nature uses for rendering anything!
-> because we don't know what destination the nature has choosen for its photons ;-)
