Someone has provided me about 60 stitched panorama's. They are cylindrical, so that's what I specify as panotype in the kmakemultires config file. The results in the viewer then are very good.
But as I want to also make a iPhone/iPad viewer for these pano's, I learned that I need cubical pano's for that. It's possible to convert spherical pano's to cubical ones, but is it also possible to convert cylindrical source images to spherical (or cubical) ones?
