// Persistence of Vision Raytracer Version 3.5 Scene Description File
// File: hollow2.pov
// Author: Dieter Bayer
// Description:
// This scene shows the effect of solid vs. hollow objects.
//
// Both spheres in this scene are enclosed by a media container object.
//
// The left sphere is solid, i.e. it's not filled with the media.
// The right sphere is hollow, i.e. it's filled with the media.
//
// Note that you can see some discontinuities in the media of the
// right sphere. This is caused be the refraction. After the rays
// are bent they travel through the media on a different path
// resulting in a different result than that for an unbent ray,
// which would show no discontinuities.
