[ptx] how to do 'correct' 360 deg. panoramas?

[Stefan M. Brandl]

Hi,
after making some panorams with 2-5 images I tried my first
360 degree panorama:

http://www.smbnet.de/tmp/cham1.jpg (done with PTStitcher)
http://www.smbnet.de/tmp/cham2.jpg (done with nona)

The problem is, that the left and rigth side are overlapping.
So I have to crop it to get a smooth transition, what is very
difficult.
Is it possible to get this automatic (left side of the image begins
where the right side ends)?

Are the any attemp to put color-correction into nona?
With nona it took a couple of minutes to stich, with
PTStitcher it took about 25 hours!



Regards
 Stefan
