The z-buffer looked pretty cool too, I thought

I ray-traced this slice of a Minecraft world--the model is from https://sketchfab.com/3d-models/high-quality-minecraft-world-94f36d42c3ba4d0ebce150b1634c37da. It took just about a second to render with the BVH checks, but it took *14 minutes* without it--a 99.88% decrease is really good! Im looking forward to how this looks once we get texture mapping implemented.

Same scene as project 5. It took roughly 40 seconds to render with just enumerating every object in the scene, roughly 7 seconds to render with just the naive AABB test, and less than a second to render with the BVH implemented.
