A year or so ago I wrote a raytracer in swift (writing RTs is how I learn languages, and they’re not the super fancy advanced feature ones, think university assignment), and actually made a BVH for a change. It is amazing the perf difference you get from binned construction, it obviously makes sense when you actually think about it, but until you do think you don’t know just how much perf you’re losing. It’s nice to see the surface area heuristic still hasn’t gone anywhere :)
