hugin inherited the lens model from panotools. There the -a-b-c term was introduced to keep approximately the same image dimensions when correcting distortions (an I assume Mr. Dersch did the right thing then, he'S a professor for mathematics after all. However, the focal length is for user convenience only since internally panotools works with the field of view solely. -- Erik Krause http://www.erik-krause.de -- A list of frequently asked questions is available at: http://wiki.panotools.org/Hugin_FAQ --- You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
