[ptx] hugin and enblend?

[Chris Cothrun]

I'm going to steer this back towards the list, I inadvertantly replied
directly instead of to the list.

There seems to be active and growing development around the most
useful aspects of Panotools. The pano12 library has seen some
significant developments lately, including a much faster optimizer and
an approximation technique for PTStitcher that puts it slightly faster
than Nona with only a small sacrifice in accuracy (.25 pixel at most,
usually much less). I believe the development is centered around the
sourceforge site (http://panotools.sourceforge.net/) but I'm not sure
all of these changes are checked into CVS there, this is one of the
useful things that shows up on the Yahoo PanoTools list.

I believe it still needs the pano12 library.

I haven't figured out whether to crop mountaintops out or if I leave
the whitespace in this one. I want to get a wide angle lens so I can
create 360x360 panos without too many shots. Its hard to justify when
its just a hobby though.

This version is much better than the original you posted.

Thats very clean for a quick pano. Clouds make for some interesting
skies but can play havoc with the exposure and contrast.
