Real-Time SAH BVH Construction for Ray Tracing Dynamic Scenes
Dmitry Sopin, Denis Bogolepov, Danila Ulyanov · 2012
This work is aimed at the development of effective algorithms for building of full SAH BVH trees on GPU in real-time. In this work it is presupposed that all the scene objects are represented by a number of triangles (the so-called “triangle soup”), at the same time the arbitrary changes in the geometry are allowed in the process of rendering. The proposed methods have allowed more than tenfold increase performance compared to the best GPU implementation known.
