Multi-hit ray traversal is a class of ray traversal algorithm that finds one or more, and possibly all, primitives intersected by a ray, ordered by point of intersection. Multi-hit traversal generalizes traditional first-hit ray traversal and is useful in computer graphics and physics-based simulation. We present several possible multi-hit implementations using Microsoft DirectX Raytracing and explore the performance of these implementations in an example GPU ray tracer.
