The algorithm is able to generate DEM models which feature similarly with real soil in terms of the particle size distribution and the void ratio.

The process of point creation in this section is similar to the method proposed by Bridson (2007). Robert Bridson. 2007. “Fast Poisson Disk Sampling in Arbitrary Dimensions”, ACM SIGGRAPH 2007 sketches, Pages 22-es
