Made a scene with a lot of teapots in different angles and materials. They are contained in a mirror-like box. Took about 4 minutes.

Same render scene as the one for the previous assignment. Render time is 0:01:32 with 6 threads, 15 bounces, without bounding boxes. Render time is 0:00:16 with 6 threads, 15 bounces, and only using the bounding boxes implemented for the previous problem. Render time is 0:00:00 with 6 threads, 15 bounces, and using the default BVH implementation.
