The radial pattern is a radial blend that wraps around the
+y-axis. The color for value 0.0 starts at the +x-direction and wraps the
color map around from east to west with 0.25 in the -z-direction, 0.5 in -x,
0.75 at +z and back to 1.0 at +x. Typically the pattern is used with a
frequency modifier to create multiple bands that radiate from the
y-axis. For example:
pigment {
radial
color_map {
[0.5 Black]
[0.5 White]
}
frequency 10
}
creates 10 white bands and 10 black bands radiating from the y axis.
The radial pattern has a default color_map built in that results
in a yellow, magenta and cyan pattern with smooth transitions.
