If you are a programmer and need a way to quickly loop over 2D/3D space or a spherical surface, this is the library for you. It provides very performant and accessible methods to coordinates in 2D coordinates, 3D coordinates, and spherical coordinates, plus a way to hash (converting to indices) each coordinate space. This library doesn't need caching due to its O(1) constant calculation time. This library is also burst compatible and the Prefab Spawnner sample scene has a job system showcasing a burst compiled job to calculate spawn positions of prefabs.
