Oh, gotcha.  Photorealistic is pretty boring to me...I was speaking of
fantasy art, which is typically very unreaslitic.  (super rich colors,
high contrast, unbelievable creatures and architexture...etc)

Well, yeah, but I'd say the lack of good geometry has hurt a lot of
stuff - trying to put too much into the texture and bump maps.
I spent most of Jurassic Park watching the texture stretching on the
dinos' skin, and I thought the vast majority of the new footage in
the Star Wars flicks was terrible compared to the live action models
they used for the original stuff.

Hum, I'll have to do that.  Only thing I know about siggraph is that
a bunch of our 3d artists went to the conference here recently.

Ah, Diamond.

Not too bad, but again it all looks 3D to me.  I think I'd like it better
if I didn't know anything at all about how rendering works, so I wouldn't
sit there and go 'hey that's the stock chain out of 3dstudio...and there's
some screwed up normals on that model right there'...

Light is probably the fundamental problem with 3d art.  Two problems -
first, 3d primatives are in no way representative of real objects.
Real objects have rounded edges, no matter how 'sharp' they may seem, so
light never reflects off 90 angle corners the same way they do a 3d cube.
This isn't as bad now that most packages come with meshsmooths and so forth
to get rid of hard edges.
Second is that the light is not modeled very well.  Real light, sunlight
especially, bounces off the surfaces it strikes.  A real object, no matter
how simple, is going to have light striking it from all sides at a billion
different angles.  Thus is as compared to a rendered object with matematical
light which doesn't reflect at all, or very little.  They try to make
up for it with 'ambient' light, which only has the effect of basically
graying out the whole image.  Hence, bad 3d art looks both washed out and
surreal.  In my experience there are very few people who can work the tools
well enough to make really beautiful art, and in the end I still like
painted stuff better. :)
