Detailed Description

btSphereSphereCollisionAlgorithm provides sphere-sphere collision detection.

Other features are frame-coherency (persistent data) and collision response. Also provides the most basic sample for custom/user btCollisionAlgorithm

iff distance positive, don't generate a new contact

distance (negative means penetration)

point on A (worldspace) btVector3 pos0 = col0->getWorldTransform().getOrigin() - radius0 * normalOnSurfaceB; point on B (worldspace)

report a contact. internally this will be kept persistent, and contact reduction is done
