Hi,

     Simply stated I have two hpr's and need to add them together.
I know its not as simple as pfAddVec3(hpr1,hpr2).

Background:
    In a flight simulator I have the aircraft's xyz,hpr. The pilot is in
a head tracked HMD so to get the camera in the correct place I need to
add the trackers hpr to the aircrafts hpr.

Thank you for your help.
Eric
