For anyone who was also curious about what BVH meant. BVH stands for Bounding Volume Hierarchy which is a tree structure on a set of geometric objects. They are used mainly in ray tracing "to eliminate potential intersection candidates within a scene by omitting geometric objects located in bounding volumes which are not intersected by the current ray." So basically they are used similarly like the Barnes Hut trees.
