Would be interested in the techniques you used to make the car - eg did you
make half a car, mirror & join?

How about a rendering of just the curves (create a pipe for each curve)

The latest trend is to use HDRI for such kind of models/scenes. In
this case your Rhino3D model could look smth. like this :)

You can find there very detailed tutorial as well.

Yes a very nice car, and I agree with Gena, HDRI rendering would be
great. Especially if you also use Tek's nice metal flake texture.

It would be awesome :-)

This tutorial explains that it's better to avoid mirror technique:

Nice car, and you've done it with Rhino ... that's a really tough interface.

But when the shape is triangulated, and the normals have been calculated,
you can still cut away half of it and save 50% memory.

Which memory do you mean - modeller or POV-Ray? As far as I know
povray doesn't have 'mirror' function yet, does it? So you still need both
parts.

Actually, I usually use mirror technique myself (sPatch) for human
faces, figures and other symmetric stuff. And as a rule the problem
is the same as described in that tutorial - to get seamless transition
from one part to another. But I doubt if it's possible to make human
face without mirror technique. Though it looks like it's not a problem
for cars.

I mean POV-Ray's memory, and mirroring is easy. For example:

scale <-1,1,1>

...mirrors any object in the X direction.  :o)

Hmm... I always suspected that I know only about 55% of POV-Ray
functionality ;)

Thats about 10 times as much as me. (But I did know the mirror trick, 
and uses it extensively.)
