works like a charm, thanks for posting this joeldg!

I was looking, like others, for this exact same thing. Quite a lifesaver!

I wanted to point out that PyOgre has a successor: python-ogre[1]. It seems to be a very active project that not only wraps Ogre but other useful stuff also.

Another engine worth mentioning in the Python world is soya3d[2]. Though not as complete, stable or well documented it is simple yet quite powerful.

I must also say that what I most liked about Panda, which sets it aside from other options is the complete documentation (targeted at Python programmers from the start).

Lastly I wanted to thank you for taking the time to write those gentoo ebuilds[3] for panda3d and I wanted to let you know that I renamed the 1.5.0 ebuild to 1.5.2 and it worked just fine.

Thanks for your work,
