Thanks for the answers. I do understand the differences of PTGui vs Hugin and PanoTools. I deliberately decided to ask the question here, because I've seen that here there are the people who "understand the maths".
What I'm asking for is a part of my much larger calibration project, where using the calibration in PTGui is only one of the steps. I do know about other calibration options, and this is not about that. To state it in short, I really need to understand how the projection and backprojection of the rays work in Panotools/Hugin/PTGui fish/lens correction model. Not the calibration, not the exact piece of software. The model. Hope one of the developers would come across the message and share the knowledge :) -- You received this message because you are subscribed to the Google Groups "Hugin and other free panoramic software" group.
