The MergeTree is a hardware architecture for constructing Bounding Volume Hierarchy trees for interactive ray tracing. The unit conserves memory bandwidth by using an external sorting algorithm for Morton code sorting, making it suitable for mobile systems. In simulations, MergeTree organizes large scenes three times faster than prior work.
