Detailed Description

template<typename BP_FP_INT_TYPE>
class btAxisSweep3Internal< BP_FP_INT_TYPE >

The internal templace class btAxisSweep3Internal implements the sweep and prune broadphase.

It uses quantized integers to represent the begin and end points for each of the 3 axis. Dont use this class directly, use btAxisSweep3 or bt32BitAxisSweep3 instead.
