Can Machines Stipple as Well as Humans?
Optimal transport is art: images to collection of optimally placed particles
Stippling, the art of creating images with dots, has been used for centuries. This blog post explores whether computers can replicate the technique. It introduces Lloyd's algorithm for generating centroidal Voronoi diagrams, which produces well-spaced points that mimic hand-drawn stippling. The author demonstrates how to implement this in Wolfram Language, showing that machine-generated stippling can achieve the same aesthetic quality as human-made art.
It turns out when using points to approximate grayscale shading, a random set of points with uniform distribution is usually not good enough.
