Integrating InertiaCube and Vicon data

[roman_suvorov]

Thanks again farshizzo. Your tip doesn't seem to help in my case though - "slerp" somehow disables position tracking. I think I am going to go with a manual solution (coding this data integration from scratch).

I don't know if this is related, but here goes: what is this error message I get every run?

Cannot open serial port? InertiaCube is indeed connected through a serial port, but seems to be working fine.
AFAIK "vizppt.dls" is a plugin for "Precision Optical Tracker", the line adding it was present in "gallery.py" example script which I'm using. Is it another tracking device I simply do not have? Is it safe to remove the lines referencing it then?
