In this paper we present a novel packet ray traversal implementation that completely eliminates the need for maintaining a stack during kd-tree traversal and that reduces the number of traversal steps per ray.

[10] presented a GPU-based, stackless kd-tree traversal algorithm for ray packets and they achieved a performance that was similar to its CPU conterpart. However, for the performance of secondary rays, they only demonstrated reflection and refraction rays.
