Floating Points: A Method for Computing Stipple Drawings

Abstract

We present a method for computer generated pen-and-ink

Generation of automatic stippling illustrations from photographs for documenting archaeological pieces

“…We are specially interested in methods that produce stippled images from 2D images and photographs. Among these methods, ), Deussen (DEUSSEN 2000, Hiller (HILLER 2003), Dalal (DALAL 2006), Barla (BARLA 2006) and , use centroidal Voronoi diagrams (CVD) to distribute the dots. Their approach has problems with patterns.…”

A unified scheme for adaptive stroke-based rendering

“…There have been a number of techniques proposed in the field of NPR, for automatically creating artistic renderings from arbitrary reference photographs [24,2,21,15,22,26,27,5,16,13,11,4,14]. Each of these techniques is designed to simulate a distinct artistic style and specific artistic medium such as oil painting, pen-and-ink illustration, watercolor painting, pencil drawing, stipple drawing, engraving, mosaics, stylized abstraction, etc.…”

“…However, the strokes have been mainly used to fill the interior of regions, while the outlines (region boundaries) are often neglected. While there are some approaches that allow partial use of outlines to enhance their styles [5,13,4], their underlying frameworks are still not general enough to cover various artistic styles or media. In our approach, the outline information serves as an essential ingredient which plays two important roles.…”

“…Also, these examples show that 'less important' regions may be purposefully abstracted, to communicate 'important' features to the viewers more effectively. Although there have been numerous NPR approaches for automatic generation of illustrations [24,2,21,15,22,26,5,27,16,13,11,4,14], none of them is general enough to produce alone all of these example rendering styles. When we take into account the comprehensive class of artistic illustrations, the following statements can be made in general:…”

Nichtrealistische Computergraphik

“…In Deutschland findet es zunehmend auch als Lehrgebiet innerhalb der konventionellen Computergraphik seinen Platz. In der algorithmischen Umsetzung dieses Verfahrens [4] analysierten wir die Punktverteilungen der Künstler und fanden heraus, dass es sich um sog. Poisson-Disc-Verteilungen handelt, Zufallsverteilungen, die einen garantierten Minimalabstand der Punkte zu ihren jeweils nächsten Nachbar besitzen.…”
