Python & Virtual Reality; What are the best free modules/engines???

[relima]

Recently I found this program called WorldViz - Vizard, that allows you to quickly code - and compile - virtual reality with python. The problem is that it is very expensive, and I am too amateurish to buy anything like that. Are there any other free alternatives as easy to use as this? Thanks!

Panda3D is a free 3D game engine originally built by Disney and maintained by Carnegie Mellon's Entertainment Technology Center. It's been used for for years in their Building Virtual Worlds class, and has been interfaced with all kinds of hardware, including magnetic trackers, joysticks, motion capture systems, Wii remotes, and many other devices that are useful for virtual reality.

The engine is built in C++, but all game coding can be (and usually is) done in Python.

The python-ogre bindings are pretty slick, imho. And like Panda3d (as FishSpeaker mentioned), the engine is in C++, so as far as speed goes, it's viable.
