SPH planetary collision simulation ( Not 100% correct. Lacks extra math ). Built on Bismuth, a custom Entity-Component-System (ECS) engine. Simulation runs on the GPU and includes an interactive GUI to control spawn parameters.
Simulation is built on Bismuth, custom ECS library. Depending on choice of iteration pattern, Bismuth can be up to 30% faster than EnTT or 10% slower (Tuple for loop). Default example scene: 15625 particles in a no-gravity environment.
