I've written a Python wrapper to allow some fast experimenting with Horde3D.
The included sample depends on pyglet 1.0.

Some functions of Horde3DUtils are not wrapped: freeMem, initOpenGL, releaseOpenGL, swapBuffers, createTGAImage.
AFAIK freeMem is only needed for createTGAImage. Creating Images should be easier with PIL which is often included with Python. The OpenGL functions are not needed since pyglet provides this functionality.

Update 2010/03/03
Updated for community svn r386.

Update: 2009/06/28
Added patch by Leon Oostrijk. Wrapper now works for community svn trunk again.

Update: 2009/02/05
Added support for sound extension.

Update: 2009/02/04
Replaced the Python bindings with pure Python bindings - no compilation / binaries are needed with these. See community svn r191: http://mm-werkstatt.informatik.uni-augsburg.de/public/Horde3D/trunk/Horde3D/Bindings/Python/


Update: 2008/10/26
community svn trunk now features doc strings for horde3d.py

Update: 2008/10/16
Added Python bindings to community svn. These will not work with Beta 2!

Update: 2008/10/15
Updated bindings to work with svn trunk (r63) / Beta 2. Maybe some new functions missing, but basic.py works.

Update: 2008/06/06
Updated Bindings to work with svn trunk (r30).

Update 2008/04/30:
Added windows binaries for r3. They run with wine, I hope under Windows, too.
URL: http://server2.noeding.net/horde3d.zip


Update 2008/04/29:
Added simple application framework for rapid prototyping
Added sample application for terrain extension and


Update 2008/04/28:
Added r2 of Python wrapper with support for terrain extension. Until I figure out how to enable / disable the terrain extension using distutils it will be enabled by default. To disable it just uncomment a line inside setup.py.






Community svn users: please use the svn version and not the files attached here!

Nice work. Checking it out now.

This should make a really nice setup. I was using pyglet directly before stumbling across Horde, and the combination should be somewhere approaching prototype-nirvana :)

I'm currently writing a small container App to reduce boilerplate code for my next tests / examples. Terrain is already working very nice :)

On the path to madness aka Windows: I've hacked Horde3D and the makefiles so that I can cross compile Horde3D for windows from Linux complete with Python wrappers. I still have to test it on a "real" windows machine but wine is happy when rendering the terrain sample using Python 2.5.2 :mrgreen:

Code is available from my gitweb inside the mingw32 branch. I'll publish the binaries after I got some sleep, it's getting somewhat late here... I'll explain what I've done then, too.

Hello (again :D),

I have done some work on the Python binding to get it compile, but the samples wouldn't work (Segfaulting in Horde3D::initOpenGLExtensions). However, that's the patch; maybe it's useful for someone: http://paste.pocoo.org/show/87306/

Or, do you maybe have any idea how to get the samples working? :)

Cheers,

Fred

Thanks for the patch.

I don't have access to my development computer until next week, then I'll try to update the bindings to beta 2 and fix the samples.

Hmm, I probably missed some fixes I did for the community svn version. I'll post an update later today / tomorrow.
