Floating points: A method for computing stipple drawings

We present a method for computer generated pen-and-ink illustrations by the simulation of stippling. In a stipple drawing, dots are used to represent tone and also material of surfaces. We create such drawings by generating a n initial dot set which is then processed by a relaxation method based on V oronoi diagrams. The point patterns generated are approximations of Poisson disc distributions and can also be used for integrating functions or the p ositioning of objects. We provide an editor similar to paint systems for in teractively creating stipple drawings. This makes it possible to create suc h drawings within a matter of hours, instead of days or even weeks when the drawing is done manually.
