panoglview on Linux
panoglview is an OpenGL hardware accelerated immersive viewer for equirectangular images, originally created by Fabian Wenzel and currently hosted on the hugin sourceforge site[*].

The license for panoglview is the GNU General Public License (GPL)[*].

You can download pre-compiled versions of panoglview as part of the hugin installer bundles for OS X and Windows. panoglview is available for linux distributions through the usual channels (e.g ubuntu getdeb[*] March 2009).

## compiling panoglview

See Hugin Compiling Ubuntu#Panoglview[*].

## using panoglview

Panoglview is intended to view full 180x360 (equirectangular) panoramas projected onto a globe which can be spun around using the mouse.

For viewing a partial panorama, you use project files. There are no examples in the distribution, but they can be created by opening an equirectangular image and saving a .paf 'project'.

These are simple text files and fairly self-explanatory, but the interesting thing is that these .paf files contain stuff like camera field-of-view, pan, tilt, boundaries and now partial panorama settings.

## as a replacement for PTEditor

PTEditor[*] is an older unsupported tool for viewing a panorama, extracting undistorted views for external editing and reinserting those edited views. The panoglview .paf saving feature can be used to imitate this functionality in conjunction with the pafextract[*] tool.

The pafextract workflow[*] goes something like this:

1. open a panorama in panoglview
2. find a viewpoint to edit, save a .paf viewpoint
3. extract a bitmap image of this view with pafextract
4. edit it with the gimp[*] or another image editor, save
5. remap this using the .pto project created by pafextract
6. merge with the panorama
