Many thanks to you guys, I found the bug and corrected it, now I can 
scan any povray objects to make them into an opengl object!

The first image is my object rendered with POV-Ray.
The second image is the result of the scan showed by my OpenGL program. 
  The second image is a stereogram, meaning you can look at it with eyes 
x-crossed and you will see the distance.

Thanks,
   Xilo

Except that my eyes can't separate that much!

Your code is nice, but as you probably know, it won't trace all objects very
well. If you want a more complete solution, check out this:

But it's a cross-eyed one, Hugo.  It works very nicely.  Good job, Xilo.

Cheers!

I don't drink that much.  ;o)
Maybe if I stand far away from the computer?
But I can usually not make it work.

You sure can... you only need a little practice, you need to be about 1 
or 2 feet (or as usual) away from the screen.

Align your head so it is perfectly perpendicular to your screen width.
Then cross your eyes so the two images mix toghether in a blurred 
anomally, then just relax let the blur become clear by your natural 
brain function to focus.  Your eyes will eventually focus on each object 
and will form a real 3D perspective...

You only need to relax and try!
Btw, it's worth it, the look of the shape in 3D is pretty nice.

I'm used to make stereograms in OpenGL to visualise 3D objects I make, 
so eventually you'll see more of them!  (Should I write a quick tutorial 
to seeing stereograms?)

I tried checking it and I seem unable to connect to the server...  Is it 
possible it is down?

Thanks,

Xilo,
You might not need to go to the trouble of
making one yourself. There are a handful of
web pages out there that provide instruction
on cross-eye and parallel "free viewing".
BTW: It is called free viewing because
no device, like a stereoscope, is used.

Try this one for cross-eye stereo free viewing.

Yes, you are right, eventually I'll remake my website with a more 
pleasant interface and I'll have a stereograms section with, links to 
tutorials like the one you sent!

Thanks a lot!
