Synopsis A regular dimpled appearance.

Description A wrapped displacement providing a regular dimpled appearance to a material. This displacement may be thought of as a grid of spheres which protrude above a material's surface. The distance between the centres of adjacent spheres is specified by argument "separation", and the radius of a sphere is set with argument "radius". The distance beneath the surface of the centres of the spheres is specified by argument "centre depth". This distance must be non-negative, and should be no greater than the radius of the spheres. A value between 0.0 and 1.0 which controls the size of a blend between the sphere and the surface is specified by argument "blend", for which a value of 0.0 indicates no blend, and a value of 1.0 maximum blend. An overall scaling factor can be specified by argument "scale"; increasing this value will make the dimples appear larger.
