rather than simply scrolling around the inside of a fixed cylinder.
Hmmmmmmm... (in bold, 12pt)
I do remember that the one time I did try some photo-stitch software a few
years ago, it had all sorts of adjustments that could be made to force
perspective of the final image (lens settings and the like)
Yes, to make them join up you need to distort the pictures according to
the original lens geometry. If you shoot with a wide angle lens you end
up joining lots of lozenge-shaped sections together, and having to crop
quite a bit top and bottom.

That's interesting, the image there is *much* more barrel-distorted than
you get when you do a normal stitch.
Compare with the perspective in the panorama on this page I uploaded
some time ago:

That's about 180 degrees across (5 individual shots and the "railway
arches" are a straight line in real life).
Post by Julespresumably the applet just maps the image onto the inside of a sphere for
display or something?
I'm missing the point as to why at the moment though. Wouldn't a cylinder
give a nicer effect (none of the warping at the corners) as well as
simplifying the input image somewhat? Or is that viewer actually a
lot cleverer than it looks and in this instance they just haven't
enabled most of the controls? Grumble, brain not working at all this
evening!
I'm not sure whether the spherical projection or a cylindrical would
look better. The spherical certainly has a "whoosh" factor!
