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