First let me point you to a problem: A company have a professional Camera/Softwaresystem which creates spherical panoramas also from fisheyeimages. This company have a very offensive habit against companies or softwaredeveloper which sells or give away software for free which are able to do the same without pay for a professional camerasystem based on a per image license ...they try to sue them because of a patent they have in the states! It was not possible for me to find a description of this patent on their webpage to know if i'm on their list if i USE panotools, so i will not give you the name or link of this company ,but only the information thet there IS an issue. ..well... free market. :( ....... infos / International Quicktime VR Association statement
