This plugin set contain 4 plugins helpful in 360° equirectangular panorama
The panorama_to_zenith_nadir and zenith_nadir_to_panorama plugins are inspired and based on algorithms published by Seb Przd on http://theseblog.free.fr/2007/08/edit-nadir-and-zenith-of.php. These plugins were developed as native, to speed-up their execution.
The fill_zenith_nadir is my own idea, that appeared after unsuccessful hours of unfair fight with high resolution panoramas with huge empty areas on zenith and nadir.
The last plugin - set_google_plus_metadata was obvious complement that enables easy publication of low-res panoramas.
Example of usage you can fing in the [Tutorial].
The plugins were developed and tested on Ubuntu 12.10 and Gimp 2.8. It is possible that Gimp 2.8 is needed for the set_google_plus_metadata. Other plugins should work with older releases.
set_google_plus_metadata plugin requires libexempi library.
In normal cases, when Gimp and libexempi development files are available, it should be enough to issue following commands:
./configure make make install
