Abstract
Electrostatic halftoning, a sampling algorithm based on electrostatic principles, is among the leading methods for stippling, dithering, and sampling. However, this approach is only applicable for a single class of dots with a uniform size and colour. In our work, we complement these ideas by advanced features for real-world applications. We propose a versatile framework for colour halftoning, hatching, and multi-class importance sampling with individual weights. Our novel approach is the first method that globally optimises the distribution of different objects in varying sizes relative to multiple given density functions. The quality, versatility, and adaptability of our approach is demonstrated in various experiments.
