This repository provides a generator for dither masks with blue-noise power spectrums. The generator is based on the algorithm introduced in the paper "Void-and-cluster method for dither array generation", by Ulichney (see References section). The generated masks are tileable and can have arbitrary resolutions. The generator runs on the GPU and recquires an OpenGL4.5 compatible card. Below is an example of a 256x256 dither mask along with its power spectrum:
A set of precomputed masks can be downloaded from the examples/ repository.
