Note: You can now get 64 bit versions from the panda 3d website - starting from 1.5.3. Saves me the effort of compiling them:-)

Not sure how this happened but I seem to be doing 64 bit versions of Panda 3D. Well, I guess I want them, so it makes sense to share. Anyway:

panda3d_1.5.1-ubuntugutsy_x86_64.deb
(Note: I've now tested the above under Hardy Heron - it works fine.)

Be warned that no sound or video playback (ffmpeg) support is available, as these have yet to be ported to 64 bit.
