A method and an apparatus for producing a long strip of three-dimensional decorative piece made of thermoplastic synthetic resin. The method for producing the strip of three-dimensional decorative piece made of thermoplastic synthetic resin according to the present invention comprises the steps of feeding a decorative strip material, preheating the decorative strip material and softening the decorative strip material with heat, shaping the decorative strip material into a strip of three-dimensional decorative piece by continuously oscillating a high-frequency in between a rotatable upper electrode roll die and a rotatable lower electrode roll die and applying high-frequency dielectric heat to the decorative strip material between the upper and lower electrode roll dies, cooling the shaped strip of three-dimensional decorative piece, and winding up the cooled strip of three-dimensional decorative piece.

A system of pointillist painting, including a colorant dispenser having a syringe configured for storing a liquid colorant, and a colorant dispensing tip operable to be moved to successive specified positions on a painting surface, where the colorant dispenser is operable to apply specified amounts of a liquid colorant to the painting surface and creating a plurality of colorant dots each having a two-dimensional coverage and three-dimensional profile at the specified positions on the painting surface; and an air nozzle coupled to the colorant dispensing tip operable to controllably direct a controlled puff of pressurized air at least one of the plurality of colorant dots already deposited on the painting surface to modify at least one of the two-dimensional coverage and three-dimensional profile thereof is disclosed.

A method of pointillist painting includes receiving a dot list including a specification of color, position, size, texture, and exclusion zone of a plurality of dots, wherein the exclusion zone of a dot represents an area that does not overlap with an exclusion zone of any other of the plurality of dots and selecting a first set of dots of a first color. A colorant dispenser may be moved to a first position of a first dot in the first set. A pre-determined amount of colorant may be applied to the first position. A measured blast of air may modify coverage and profile of the applied colorant. The dispenser may then move to the remaining positions until all dots of the first color and subsequent sets of dots of subsequent colors are dispensed.
