RUCAP UM-5 tracker

RUCAP UM-5 tracker is a wireless joystick for view control in PyMol. The code based on project ImmersiveViz.

Our system contains a head tracking thread which communicates the users position to a PyMol script via a socket. The PyMol script unpacks the message and updates the world respectively. All rotation is done around the virtual origin in PyMol and zoom is also considered.
