Panorama Tools
Panorama Tools (also known as PanoTools) are a suite of programs and libraries originally written by the German physics and mathematics professor Helmut Dersch. Panorama Tools provides a powerful framework for re-projecting and blending multiple source images into immersive panoramics of many types. An updated version of the Panorama Tools library serves as the underlying core engine for many software panorama GUI front-ends.
History
Dersch started development on Panorama Tools in 1998, producing software available for creating panoramas and more, but had to stop development in 2001 due to legal harassment and claims of patent infringement by the company IPIX. Dersch released the core library (pano12) and some of the programs of Panorama Tools under the terms of the GNU General Public License. The rest of the applications were made available as binary executables only and for free without a copyleft license.
The development of the source code of Panorama Tools was continued by some members of the original Panorama Tools mailing list. In December 2003 they initiated a free software project which is currently hosted by SourceForge. SourceForge requires that all hosted software is released under an open source license. For this reason Dersch's unlicensed binaries are not hosted there, although they can still be found on mirror websites.
