[IGSTK-Users] About pivot calibration

[Patrick Cheng]

Hi Hyungmin Kim,

What is the "DRB" you are referring to?

Is it reference tool? If you choose to use a reference tool when you 
initialize the tracker, it has to be visible for you get any valid data 
for other tools.

You are right about you don't need reference tool for calibration process.
