Hi Klaus,
Hotspots, for example image hotspots that have been distorted and aligned to objects inside the panorama, do not align well when the view is switched to Pannini. They do align well in fisheye and stereographic. You can test this with a simple image hotspot distorted to fit a pictue on a wall in the panorama. In pannini it won't align well. Am I doing something wrong or is this a bug?
Regards,
Karel
