Axis‐Normalized Ray‐Box Intersection
Computer Graphics Forum, Volume 44, Issue 2, May 2025.Abstract Ray‐axis aligned bounding box intersection tests play a crucial role in the runtime performance of many rendering applications, driven not by complexity but mainly by the volume of tests required. While existing solutions were believed to be pretty much optimal in terms of runtime on current hardware, our paper introduces a new intersection ...

SOBB: Skewed Oriented Bounding Boxes for Ray Tracing
Computer Graphics Forum, Volume 44, Issue 2, May 2025.Abstract We propose skewed oriented bounding boxes (SOBB) as a novel bounding primitive for accelerating the calculation of ray‐scene intersections. SOBBs have the same memory footprint as the well‐known oriented bounding boxes (OBB) and can be used with a similar ray intersection algorithm. We propose an efficient algorithm for constructing a BVH with

Trichobezoars as a cause of intestinal obstruction in a young female [PDF]
, 2019 A bezoar is a mass found trapped in the gastrointestinal system, though it can occur in other locations. There are various types of bezoars including food boluses, lactobezoar, pharmacobezoar, phytobezoar, diospyrobezoar and trichobezoar. They are common
