A Rendering Method of Virtual Drypoint by a Physical Model

Abstract

In this paper we propose a method to rendering a virtual copperplate print image based on a physical model as a method with non-photorealistic rendering. In particular we pick out the drypoint from many existing copperplate printing techniques. A drypoint print has a remarkable feature that ridged burrs are arising out of the copperplate and the printed lines are slightly ragged and fuzzy. Our method consists of four sub-processes, which simulates the physical actions and phenomena observed in the actual copperplate printing. We indicate effects and availability of proposed method to synthesize a print image with the feature of drypotin by some experiments.
