# Low-Discrepancy Blue Noise Sampling

![C/C++ CI](https://github.com/dcoeurjo/LowDiscBlueNoise/workflows/C/C++%20CI/badge.svg)

**Super fast Low-discrepancy + Blue noise 2D sampler.**

Single C++ header with no dependencies to generate 2D point sets which have both [low discrepancy](https://en.wikipedia.org/wiki/Low-discrepancy_sequence) and Blue-Noise properties. This code is a c++ refactoring of the implementation given by the following paper ([Project page](https://projet.liris.cnrs.fr/ldbn/)):

    Low-Discrepancy Blue Noise Sampling.

    Abdalla G.M. Ahmed, Hélène Perrier, David Coeurjolly, Victor Ostromoukhov, Jianwei Guo, Dong-Ming Yan, Hui HUANG, Oliver Deussen.

    ACM Transactions on Graphics (Proceedings of SIGGRAPH Asia), 35(6), 2016.

The current code can generate point sets for the  Blue-noise and Step target spectra in a very efficient way (~2.14ms for 1M points! , cf the paper for more details).
