Sors, Lathes, Prisms, While Loops, and CSG are our friends. They
can help you make some very realistic vases without having to
resort to a triangle mess.

I'd add illumination as one of keywords for realistic rendering: it can
make otherwise average picture outstanding (and vice versa, of course).

It might be interesting to make two versions of an image: one which goes
into a lot of very tiny details but is "perfect", for example, having
books on a shelf perfectly aligned, papers on a table in a stack
centered in the middle, etc, as well as a real-world version with the
same level of detail but with randomness and noise introduced into the
scene: knots in wood panels, leaning books, scattered pens/pencils,
smudges of dirt and dust, etc.

The granite and wrinkles patterns are examples of fractal noise, as well
as the turbulence warp, etc. In MegaPOV, you also have Ridged and Hetero
Multifractals, and can make fractal noise patterns with the function {}
pattern.

There is someone working on a shader patch...it isn't a simple addition,
however.

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
