A Survey on Bounding Volume Hierarchies for Ray Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2021)
Ray tracing is an inherent part of photorealistic image synthesis algorithms. The problem of ray tracing is to find the nearest intersection with a given ray and scene. Although this geometric operation is relatively simple, ...
Ray Tracing Lossy Compressed Grid Primitives
(The Eurographics Association, 2021)
We propose a new watertight representation of geometry for ray tracing highly complex scenes in a memory efficient manner. Polygon meshes in the scene are first converted into compressed grid primitives, which are represented ...
