Sounds nice, I would like to try the difference!
I've put a binary here for testing: http://haikubeat.free.fr/files/testing/GLTeapot_worldspace.zip :-)
To do so, the cleanest way was to use simple (and beautyfull) quaternion math. I took http://www.bulletphysics.com implementation (ZLib license, i think it's ok?) as i'm familiar with it (i refactored/restyled btQuaternion.h from the LinearMath library). I think i just have to put our license header above or under theirs, no?

Yes, but don't forget to put their license in the AboutSystem app too.

Ok i'll do that. But is it really needed? Even if it's only one small file and not the whole lib (LinearMath)?

Very nice! Thanks for sharing. The vehicle demo makes me want to program a little game... :-)


Hehe, i've been dreaming of a Haiku Kart in the past months :-D And what about a multi-threaded physics demo, with an Haiku logo and physically animated leafs? The app with bullet statically linked would take around 200k from my experience. And the Bullet source is around 1 meg, if we ever want to include it in the repository.

Bye,
Alex
