Im progressing with my general panoramic skills and ordered NN5L to give a try to spherical panoramas. Up to date Ive built several spherical panoramas using photos&tutorials from the Web (special thanks here to John Houghton for his excellent tutorials on PTGui). My question here regards software designed to convert equirectangular projections to cubic faces as they make it easier to introduce corrections to nadir image in example. Ive noticed that most often referenced software is pano2QTVR. But there also is a new version called pano2VR, which as claimed by the developer, is much improved, but almost twice as expensive. Do any of you can make a recommendation of which version to choose? Are there any other programs similar to pano2QTVR/pano2VR?
