    • Ray Specialized Contraction on Bounding Volume Hierarchies 

      Gu, Yan; He, Yong; Blelloch, Guy E. (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      In this paper we propose a simple but effective method to modify a BVH based on ray distribution for improved ray tracing performance. Our method starts with an initial BVH generated by any state-of-the-art offline algorithm. ...
