avoid collision response between two static objects

Bullet has several options to set the friction directions By default, each contact has only a single friction direction that is recomputed automatically every frame based on the relative linear velocity. If the relative velocity is zero, it will automatically compute a friction direction.

You can also enable two friction directions, using the SOLVER_USE_2_FRICTION_DIRECTIONS. In that case, the second friction direction will be orthogonal to both contact normal and first friction direction.

If you choose SOLVER_DISABLE_VELOCITY_DEPENDENT_FRICTION_DIRECTION, then the friction will be independent from the relative projected velocity.

The user can manually override the friction directions for certain contacts using a contact callback, and set the cp.m_lateralFrictionInitialized to true In that case, you can set the target relative motion in each friction direction (cp.m_contactMotion1 and cp.m_contactMotion2) this will give a conveyor belt effect
