Transformation between Camera Tracker (PV) and HMD Display (HMD)

[nocardio]

Hi @doughtmw ,

Sorry to disturb you again :)
While I read the reference paper for your display calibration [Azimi et al, 2017], they described three coordinate systems for calibration with head-anchored tracking system: camera tracker (C), object (O), and HMD Display (H).
Could you please explain to me how did you solve the transformation between C and H? Or could you please direct me to the part of your code to get this transformation? As I remembered, you didn't mention about this transformation in your paper.

Thank a lot for your help!
