// Persistence Of Vision raytracer version 3.5 sample file.
// "Black and White Stripes"
// Copyright 2001 Rune S. Johansen

// This scene makes use of a contrast enhancing filter.
// For more information, see the demo scene transmitfx.pov
// located in the folder \scenes\textures\pigments\

// The idea is to create a woodcut look where dark areas are
// made of thick black stripes and bright areas are made of
// thin black stripes. This effect is achieved by giving all
// objects a grayish gradient pigment. The brighter parts of
// the gradient becomes white and the darker parts black.
// Because the light from the light_source also makes the
// gradient brighter, the white stripes are more dominant in
// the illuminated areas on the objects.

camera {
	location <0, 6,-10>
	look_at 4*y
}

// A small sphere around the camera location with a
// contrast enhasing texture.
// (Also try to render with this sphere commented out
// to see how the scene looks without the filter.)
sphere {
	<0, 6,-10>, 0.001 hollow
	pigment {color rgb 0.5 transmit 100}
	finish {ambient 1 diffuse 0}
}

// A light source
light_source {<0, 10, 0>, color 1}

// The grayish gradient pigment which is applied to all
// objects in the scene by making it the default.

	texture {
		pigment {
