I've heard this too ;-)
But creating this patch is only half of problem, other part would be
creating of useful shaders. If I look into BMRT shaders, then I can't
imagine, how they are created. (Only idea is that someone throw
expressions into shader source code, massaged it long enough to compile
and then looked to output ;-)
If I manage to get enough time for reading "Texturing and Modeling",
(which is waiting in bookself), then perhaps I get better idea of
procedural shaders...

I seem to remember coming across a tutorial/general discussion about making
scenes realistically dirty and disorganised. The main example was a render
of a workbench, but I can't track the link down in pov links (Ken?). Anyone
know the link I'm after? (Ken?).
Maybe Ken will know. (Ken?).
BTW Could Ken distribute signal watches, like Superman gave to Jimmy and
Louis?

It's gone. It was at serious3d.com, but they had some financial troubles
or something and are no more. The tutorial you're thinking of was written
by Bill Fleming, whose home is at http://www.komodostudio.com/ . He has
info there on his various books on photorealism, one of which is an
expanded version of the article you remember.

It was from a book written by Bill Flemming.
> Anyone know the link I'm after? (Ken?).
I know the link but the site is no longer available so it would do
you no good.

I know.

Pagers are cheaper and more redily available.

Whoops, guess it's not gone. It's just moved. Try

take a look at http://www.3dluvr.com/marcosss/morearni/ - view the one in
the middle - the little guy with the gun - this was the most realistic
rendering I have seen

the vase itself isn't the problem
its all the little grooves
I could approximate it possibly by making lots of tiny cylinders and having
those copyied along a spline path. it would be more work then its worth
though..
also it wouldn't be as accurate as the rhino model

That is a very long render time. Did you use photons?
Seems to me that the single most important aspect of a quality
photorealistic rendering is how the lighting is set up. I saw an excellent
example on lighting and postprocessing at this location:
http://3drender.com/jbirn/ea/Ant.html
It is very brief but pictures say alot and you can glean ideas from such
articles.
If you master this sort of thing then you can render excellent
photorealistic pictures of fake-looking objects with fake-looking textures!

no photons, just 1 area light and a point light (acting as a fill light)
