This is another vertical projection, based on a panorama taken near Goriano Sicoli (parco nazionale del Sirente). Title arises from the two close hills that give two gibbous deviations to circular horizon line, with a shape similar to water molecule. I know someone don't like this "innatural" projection, but someone else showed some interest on it, so I want to publish this last one with some additional explaination. The starting point is how to rapresent a 360° panorama on a flat image; this issue is similar to the globe map projection: the distorsion are unaivoidable. In this case, I solved the issue by adding to the original stitch (assembled using Autostitch) two "dark" regions below and above to it, in order to have 360°x180° panorama. Then, using PovRay (which is a 3D rendering software), I used this image for cylindrical texture, reprojecting it on a sphere. The result is similar to a "polar" projection (the polar projection is an azimuthal projection drawn to show Arctic and Antarctic areas). Owners of Yahoo account can look to this impressive gallery of FULL 360°x180° panoramas: http://www.flickr.com/photos/gadl/sets/72157594279945875/ enjoy!
