Description A wrapped texture giving a polka-dot pattern. The texture corresponds to a grid of circles of one colour against a background of another colour. The colour of the spots is specified by the argument "spot colour" and that of the background by argument "background colour". The radius of the circles is specified by argument "radius", and the distance between centres of adjacent circles by argument "separation". A factor in the range 0.0 to 1.0 which is provided in argument "edge softness" controls the softness of the circle boundaries. A value of 0.0 gives a hard edge to the circles, and a value of 1.0 gives a continuous blend of colour throughout each circle. An overall scaling factor may be specified by argument "scale"; increasing this value will make the circles appear larger.
