Dear list. Seg_0.05 is out : I've had some basics physics behaviors to the seg object. This is done with mostly 4 simple abstractions : mass, spring, damping & force. Thoses abstractions can be uses without seg. (it could be very nice to uses them with GEM for ex.) you can find all of this @ http://dh7.free.fr + somes new screenshots. cheers. Damien.
