Does anyone out there know where I can make a 3D-San of my self and
maybe of some of my friends!

Wow... even if this was possible (though I can't imagine how it could be
done very accurately... lasers perhaps?) I would assume such a thing would
be very expensive - even if you could find somewhere that would do it...

All I can recommend is you get someone with good spatch/moray modeling
skills... ;)

There are plently of laser scanners out there at the moment.  The problem
you've got to watch is the incredible amout of data they produce (hundreds
of megs).  The other way is sound which is very unreliable and the other is
generally magnetic.  There is also the Microscribe by Immersion, I hear it's
very good.

Why not use a 2D photo and use it as a heightfield??

Because there's no way of rotating it and it looking good.  The only way to
get a real model of real 3D geometry is to capture it in some way to measure
depth and angles.  For instance, the laser method uses a laser to cast a
sharp line along the object(s)'(s) surface and then input video in infared
and deciphers the line's shape and distance to create the 3D geometry.

Highfields just aren't good enough for complex models.

'Cause the brightness in a photograph is not proportional
to the 'height' at that point. And vice versa: That's why
real heightfields of, say, faces actually don't look very
realistic.

These things really exist? For the public?
Cool.. well, in that case I apologise for the ignorance of my last post ;)

Technology eh?

There are progams available that will let you create your 3D model using
two or more photos taken at differient angles from a known distance (that's
how the dem files are created from satellite photos).

Yeah, I couldn't beleive it when I first heard about it.  They can actually
use ultrasonic sound waves to triangulate the position!

Or magnetic imagers!  It all sounds like SF!

Have you seen what they've done now but, IT'S INCREDIBLE!  Instead of an
ultrasound, you can get a density model of your baby.  Yep, you can actually
see a 3D model of your baby on a computer and rotate and look at it in 3D
space before it's even born!

The two programs I know of that can do this are:
3D Builder
and PhotoModeler.

I think both are in the $600-$800 range.
