[Bf-committers] Re: physics test suite

No. 

Bullet allows very stable simulation of rigid body dynamics, and most of the 
physics demos should run quite well. 

But just like with other physics engines, it requires careful setup and it 
is easy to mess up by inexperienced users. This is one of the reasons why 
some commercial physics engines make their money: supporting developers to 
make sure they author the objects in the right way, and how to avoid bad 
situations (too small objects, very heavy on top of very small, too thin 
objects and many more). 

The Bullet Website has a Wiki with Physics Tips. Also there is a forum to 
ask questions how to improve your simulation. 

It is better to have this discussion on the physics forum, rather then on 
this committers mailinglist.
Just visit http://bulletphysics.com 

Thanks,
Erwin
