I want to show my virtual tours or panoramas on my website — but how?
You are asking how to actually publish your panorama once you have stitched it. First of all, check out my tutorial video about this topic.
Then, if you are a PTGui user, don’t forget that you get a Desktop and Mobile capable viewer for free with it.
Making virtual tours, however, is a more involved thing. While I can’t list all available players, but probably the most powerful tool for this would be the KRpano player (you might want to use Kolor’s Panotour tool as a GUI). Alternatively (and I can’t possibly list all, plus I don’t have first-hand experience with them) have a look at Pano2VR or Flashificator. And here are listed some more (1, 2).
