Mathematica and MathGL3d exports 
  - DXF
  - VRML 2.0
  - QuickDraw 3D
  - PovRay 3.1
  - RenderMan

Mathmatica alone can export DXF and 3Script files.

Strange -- why Mathematica 4.x (Win/Mac) come with an OpenGL libray for
the RealTime3D`
context ? To fill the hard disk ? A OpenGL driver typical use the 3d
hardware.

Hmm, there are atleast 3 programs that are build with this "not a good
idea"
The GLExplorer, the Dynamic Visualizer and MathGL3d.

I can tell you that at least MathGL3d is an excelent idea. It is a
powerful
and easy to use visualisation system.

Ah I understand - thats why there is a GNU C/C++ compiler, portable
class
librays (wxWindows, Qt, gtk+)
