Maximal Poisson-disk Sampling in 2D, without approximations or rejections, in deterministic linear time, using chocks. A chock is a curved region bounded by a disk, a tangent, and a ray. Our formula for inverse transform sampling over chocks is numerically closed.

The main purpose of this software is to reproduce the results, data and figures, in the following publication:

"Deterministic Linear Time for Maximal Poisson-Disk Sampling using Chocks without Rejection or Approximation" by Scott A. Mitchell. Accepted to Eurographics Symposium on Geometry Processing, SGP, 2022.

A CMakeLists.txt file is provided.
The software has been compiled using Xcode on Mac OS X, and cmake and gcc on Linux. The code uses c++11 extensions. The code is self-contained and there are no library dependencies. See the "main" method in the main.cpp file, which generates the figures (or data for the figures) from the paper. There are other top-level methods, by default commented out, for unit testing and generating distributions over rectangles of different sizes and periodicity.
