Detailed Description

This class computes the collision detection algorithms.

We first perform a broad-phase algorithm to know which pairs of bodies can collide and then we run a narrow-phase algorithm to compute the collision contacts between bodies.

RP3D_FORCE_INLINE void reactphysics3d::CollisionDetectionSystem::askForBroadPhaseCollisionCheck

(

Collider *

collider

)

Ask for a collision shape to be tested again during broad-phase.

We simply put the shape in the array of collision shape that have moved in the previous frame so that it is tested for collision again in the broad-phase.
