bt32BitAxisSweep3 Class Reference

#include <btAxisSweep3.h>

Inheritance diagram for bt32BitAxisSweep3:

btAxisSweep3Internal< unsigned int > btBroadphaseInterface

List of all members.


Detailed Description

The bt32BitAxisSweep3 allows higher precision quantization and more objects compared to the btAxisSweep3 sweep and prune. This comes at the cost of more memory per handle, and a bit slower performance. It uses arrays rather then lists for storage of the 3 axis.
