Detailed Description

Class representing a transformation (translation and rotation) for the positional tracking module.

It can be used to create any type of Matrix4x4 or sl::Matrix4f that must be specifically used for handling a rotation and position information (OpenGL, Tracking, etc.).
It inherits from the generic sl::Matrix4f class.
