Line Drawings that Appear Unsharp

摘要

A straight line, pert-drawn and executed on a pen-plotter, is by default sharp and crisp. This is the nature of a straight line between two points. Likewise, drawings generated from such lines are by definition sharp. This paper considers generative line drawings, executed on a pen-plotter which appears to be wholly or in part unsharp when viewed. Described here are some strategies based on systematic experiments with geometric transformations to produce such drawings. The topic is approached from an artist s point of view with a focus on the generative and algorithmic issues involved, and the results are demonstrated by examples.
