A set of digital potteries generated by our algorithm. |
We have designed a novel algorithm to create digital potteries using certain simple-yet-efficient
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
w.r.t. 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.
