Re: MultiBody and RigidBody: architectural design of an application

I would like to focus on this. I often need to connect a btRigidBody A to a btRigidBody B (with a constraint). Normally, I need to set the btRigidBody B as static (mass 0) and setup the correct mass after the attach is done. If I don't do that, the btRigidBody B apply a huge force on A (because con...

Re: Strange Behaviour in Release Only

i only find the include file is differnent, btBulletCollisionCommon.h vs. btBulletDynamicsCommon.h. i don't known why it cause this strange behaviour.

Re: Friction problem - Sphere isnt rolling on a straight line.

this is my understanding, hope it can help you. 1. "I have same problem on version 2.83, then I'm update to 2.88 but problem still exist." --> if we set the SOLVER_INTERLEAVE_CONTACT_AND_FRICTION_CONSTRAINTS, the rollingfriction doesn't take effect on version 2.83, but it always is enabled...

Re: Is there SAT algorithm in Bullet Physics Engine

i think you should implement it yourself, but you can refer to the GPU part computeConvexConvexContactsGPUSAT()
