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 decreases 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.
