autopano-sift is still provided although autopano now is
commercial. Thats a very nice gesture from the autopano team IMHO.
It is somewhat questionable - as autostitch is patented. But ... it
does not matter any more as autopano now is commercial and paying
royalties to UBC.
If you are even more serious you shall buy autopano - it is using
autostitch. (
http://www.autopano.net/ ) €99
Or maybe serif (
www.serif.com). $49.95
As a side note - we at Proxel was negotiating with UBC to get a
license. But they wanted lots of royalty even if we did not sell -
so we could not afford as we were newly started. It was too risky.
