#### Planar

The `planar` pattern creates a horizontal stripe plus or minus one unit above and below the X-Z plane. It is computed by:

value =1.0- min(1, abs(Y))

It starts at 1.0 at the origin and increases to a minimum value of 0.0 as the Y values approaches a distance of 1 unit from the X-Z plane. It remains at 0.0 for all areas beyond that distance. This pattern was originally created for use with `halo` or `media` but it may be used anywhere any pattern may be used.
