Gimme DOTS Geometry is a collection of tools and algorithms which enable you to improve the performance of your games. A big focus is the efficient management of thousands of entities (for example boids) and GameObjects.
However it also includes Polygons (supporting an arbitrary amount of holes), collider optimization (finding the minimum enclosing sphere for a procedurally generated mesh for example) and a lot more!
Oh yeah, and there is also an implementation of a NativeSortedList in DOTS (skip list). I thought I should mention that 😏 Interested?
