I Tried Rendering Millions Of Particles

Buy a shirt! - https://acerola.gg/

Cool particle systems have been popping up in games across the last decade. Why are these novel particle systems a new thing? What tech enables them? How many particles can a midrange gpu draw?

Topics covered: particle definition, gpu instancing, iterated function systems, the chaos game, matrix transformations, linear interpolation, fragment shader bottlenecks, point list meshes, extensions and applications of iterated function systems
