What about doing something similar to the tiled traversal that we used for the rasterization assignment? I.e. repeatedly split the bounding box into smaller boxes depending on where the ray hits?
But I guess it wouldn't be much of an improvement because we would have to keep track of which triangles live in which bounding boxes.

Why the bounding boxes are always parallel with x and y axises? Can they have some angles?

I had the same question, if that approach was good for the triangle rasterization case, why wouldn't it work here.
