The plugin consists of a multithreaded simulation core and a set of tools for defining particle behaviors as well as their environment. Nuclei features unique voxel implementations for a powerful approach where particles adapt their behavior based on the highly customizable environment.

The Physarum Polycephalum algorithm mechanics are based on Jeff Jones' paper titled Characteristics of Pattern Formation and Evolution in Approximations of Physarum Transport Networks
