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.

Getting UM-5 data of the users position into socket by your script rucap.py

# -*- coding: cp1251
# Take data from UM-5 and put to the socket on port 4440.
#----- The server used to listen for head tracking
#		self.server = Server(self, 4440)
#----- The server used to listen for the GUI to update the values / display info
#		self.gui = Server(self, 4441)
