[OLPC-Games] New project: Treenimation

Fri Oct 5 08:04:28 EDT 2007

Sorry, continuing..

but isn't impossible. You can take a try to check by yourself the
speed and performance. The same for pyopengl or pysoya, libs for 3d
rendering which uses OpenGL

Thirdly:

Python + PyGame + some python 3d lib runs on Windows.

Fourthly:
 but python runs on windows very well :)

You can also use PyPy (isn't stable yet I think) or Psyco to compile
Python in native code and maybe get a better performance. I know how
hard is to use another language / platform to program your game, but
this can ease your work, as porting delphi to XO will not be an easy
job, I think this will spend a lot of time and will not help so much
the windows 'paid' version if you do a python game for XO and delphi
for windows (one project will never help the other with new features,
you'll need always to recode)

Just take a look on Python + PyGame + PySoya or PyOpengl or any other 3d lib!
