Detailed Description

The btMultiSapBroadphase is a research project, not recommended to use in production. Use btAxisSweep3 or btDbvtBroadphase instead. The btMultiSapBroadphase is a broadphase that contains multiple SAP broadphases. The user can add SAP broadphases that cover the world. A btBroadphaseProxy can be in multiple child broadphases at the same time. A btQuantizedBvh acceleration structures finds overlapping SAPs for each btBroadphaseProxy.

void btMultiSapBroadphase::calculateOverlappingPairs ( btDispatcher * dispatcher ) [virtual]

calculateOverlappingPairs is optional: incremental algorithms (sweep and prune) might do it during the set aabb

if you don't like to skip the invalid pairs in the array, execute following code:

this should deal with inserting/removal into child broadphases
