An overall scaling factor may be specified by Scale; increasing its value will make the spheres appear larger.
A solid texture giving a polka-dot pattern. The texture may be thought of
as a three-dimensional lattice of spheres of a given color suspended in a
uniform medium with a different color. The color of the spheres is specified by
the value Spot Color and that of the background by the value BackGround Color.
The radius of the spheres is specified by Radius,
and the distance between centers of adjacent spheres by Separation.
A factor in the range 0.0 to 1.0 which is provided with Edge Softness controls the softness of the sphere boundaries. A value of 0.0
gives a hard edge to the spheres, and a value of 1.0 gives a continuous blend of
color throughout each sphere.
