Abstract: This paper introduces a novel technique to create digital potteries using certain number-theoretic techniques of digital geometry. Given a digital generatrix, the proposed wheel-throwing procedure works with a few primitive integer computations only, wherein lies its strength and novelty. The digital surface created out of the digital wheel-throwing is digitally connected and irreducible when the digital generatrix is an irreducible digital curve segment, which ensures its successful rendition with a realistic finish, whatsoever may be the zoom factor. The proposed technique is also bestowed with the desired quality of producing a monotone or a non-monotone digital surface of revolution depending on whether or not the digital generatrix is monotone with respect to the axis of revolution. Thick-walled potteries, therefore, can be created successfully and efficiently to have the final product ultimately resembling a real-life pottery. Experimental results with some typical generatrices demonstrate its efficiency, elegance and versatility.
