// Persistence of Vision Raytracer Version 3.5 Scene Description File
// File: isosurfaces.pov
// Last updated: 8/5/01
// Author: Chris Huff
// Description: Various isosurfaces.
// From left to right, top to bottom:
// 1: simple plane
// 2: simple sphere
// 3: simple cylinder
// 4: parabolic (like a headlight reflector)
// 5: parallel ripples on a plane
// 6: radial ridges on a sphere
// 7: a bumpy cylinder
// 8: a potato chip
// 9: radial ripples on a plane
// 10: dog chew toy
// 11: simple cone (cylinder with varying radius)
// This can be made single-ended, replace abs(y) with max(y, 0).
// 12: a kind of spindle shape
//
