Tools functions to compute the rotation angles

Hi Klaus, is there a function or maybe rotation in krpano to compute the new angles after rotation ?

For better understaning of my question there is an example

I have Front distored hotspot at ath=0, atv=0 and rz=0 (those stands for yaw, pitch and roll) and Left distored hotspot at (ath=90, atv=0, rz=0) my question is how can I determine in krpano the new atv, ath and rz of the Left hotspot when I apply changes to atv and rz ,say to 5 degrees, (like changing the pitch and roll angle) of the Front hotspot and having Left hostpot as a child to Front.

so when Front(ath=0, atv=0, rz=0) Left(ath=90, atv=0, rz=0)

when Front(ath=0, atv=5, rz=5) Left(ath=?, atv=?, rz=?)
