Cylindrical images as used in QTVR or other viewers have to be converted to
the equirectangular projection, which can easily be accomplished using the
free Panorama Tools
Also from documentation:
tiltmin - minimum tilt angle (-90 to 0, default -90 for spherical,
or -vertical field of view for ***cylindrical*** panos)
tiltmax - maximum tilt angle (90 to 0, default 90 for spherical, or
vertical field of view for ***cylindrical*** panos)
In the latter, he is refering (I believe) to "partial" Sphere panoramas.
There would also need to be a parameter specifying the viewer shape...and
there is not one...
So the answer is no cylinder..
The partial sphere looks identical and once the cone of vision gets wide
(100 degrees+) sphere will have a noticeably smaller file size....
