Most of my panoramas are equirectangular. That works perfectly well with Immervision Pure player or Pano2Qtvr, but with Flash Panorama Player, the nadir looks like a spiral. Does anyone have a clue as to what causes this effect (and how I can avoid it)?
Since I posted this question in more than one forum, it seems appropriate to let you know about the reply I got somewhere else. There seems to be a bug in FPP with equirectangular images. I goit the advise to make panoramas using cubefaces. An annoying thing to find out after I've filled a website with 20 equirectangular panos, but at least there is a solution.
