vrpn_Tracker_Isotrak.h

// vrpn_Tracker_Isotrak.h
//  This file contains the code to operate a Polhemus Isotrack Tracker.
//  This file is based on the vrpn_Tracker_Fastrack.C file, with modifications made
//  to allow it to operate a Isotrack instead. The modifications are based
//  on the old version of the Isotrack driver.
//  This version was written in the Spring 2006 by Bruno Herbelin.
