btTransform Class Reference

#include <btTransform.h>

List of all members.


Detailed Description

The btTransform class supports rigid transforms with only translation and rotation and no scaling/shear. It can be used in combination with btVector3, btQuaternion and btMatrix3x3 linear algebra classes.
