Use this method to allow to generate multiple contact points between at once, between two objects using the generic convex-convex algorithm. By default, this feature is disabled for best performance.

Parameters:

numPerturbationIterations - controls the number of collision queries. Set it to zero to disable the feature.

minimumPointsPerturbationThreshold - is the minimum number of points in the contact cache, above which the feature is disabled 3 is a good value for both params, if you want to enable the feature. This is because the default contact cache contains a maximum of 4 points, and one collision query at the unperturbed orientation is performed first. See Bullet/Demos/CollisionDemo for an example how this feature gathers multiple points. \todo we could add a per-object setting of those parameters, for level-of-detail collision detection.
