What panorama players are available? How does the choice of player affect the way a panorama performs? Is the image rendered differently? How long does it take to load? These examples show over a dozen different panorama players, each using basic settings and copies of the same source images, to help find answers to questions such as these.

The panorama players shown here include the venerable (but possibly fading) QuickTime VR itself, a number of Flash and Java-based players (well-known and otherwise), Shockwave, a couple of entirely custom-coded engines, and one that uses Microsoft's Silverlight platform. Among these are the best in the panorama industry, although it is up to you to decide which those are.
