When you rotate the panorama using Numerical Transform, PTGui actually
modifies the yaw/pitch/roll of each source image. The calculation is not
trivial, you need to be familiar with 3d rotation matrices or quaternions.

I've asked ChatGPT to summarize the calculation:

yaw/pitch/roll is the origin around that information in the project file

I uploaded 2 files, one for the initial project and the other for the roll turned 90 degrees. The values for the first image are "yaw": -7.98349257496823839e-1, "pitch": 3.17748881327908634e1, "roll": -1.51594689439974672e-1, and for the roll turned 90 degrees, the values are "yaw": -3.17773781695759681e1, "pitch": -6.78689429270036726e-1, "roll": -8.97311776792862617e1. Could you provide a detailed introduction to this calculation process? For example, what are the Eigen values calculated from the first image using yaw, pitch, and roll?
