erwin.coumans	7eebb79ced	implemented rolling friction, using a contact constraint. Useful to get rolling spheres to rest, even on a slightly sloped plane. ... See http://www.youtube.com/watch?v=RV7sBAsKu4M and Bullet/Demos/RollingFrictionDemo Fixes in FractureDemo (mouse picking constraint needs to be removed, otherwise constraint solver crashes/asserts)	2012-09-15 06:52:17 +00:00
erwin.coumans	54744b6ab9	added gyroscopic force option for btRigidBody, body->setFlags(BT_ENABLE_GYROPSCOPIC_FORCE); ... Note that it can easily introduce instability at regular (60Hertz) simulation steps so it is generally best to not use the option. If needed, use a very small internal step, such as 1000 Hertz (world->stepSimulation(dt,100,1./1000.f); or stepSimulation(1./1000.,0);	2012-09-14 21:39:48 +00:00
