// Persistence Of Vision Ray Tracer Scene Description File
// File: qtvrPanorama.pov
// Desc: Show how to design a QuickTime VR panoramic movie file.
//       After rendering this at 384x1248, you need to use
//       Apple's free application "Make QTVR Panorama" to
//       turn it into a panorama movie that can be displayed with
//       Apple's QTVR Player.
//
//       If you want better resolution, try any multiple of 4
//       for width, and multiple of 96 for height.  A good
//       high resolution QTVR scene would be 756x2016.
//
//       This scene is just a quick proof-of-concept, not a
//       full-fledged Myst environment!
