Fast Stippling based on Weighted Centroidal Voronoi Diagrams

Abstract

Stippling is an artistic technique that has been used profusely in antiquity. One of the main problems is that it requires great skill and patience to achieve excellent results due to the large number of points that must be drawn even for small formats. The use of computers, in general, and GPUs, in particular, with their computing capacity, has allowed to overcome many of these limits. We present a real-time GPU stippling program that combines the advantages of positioning based on Weighted Centroidal Voronoi Diagrams and the realistic aspect of the scanned points.
