However, such hierarchies typically exhibit large overlap between bounding volumes, which results in an inefficient traversal. This work builds upon the concept of spatially partitioning nodes during tree construction in order to reduce overlap in the presence of moving objects. The resulting hierarchies are often significantly cheaper to traverse than those generated by classic approaches.I.3.7 [Computing Methodologies]ComputerGraphics Three Dimensional Graphics and RealismRay tracingbounding volume hierarchiesmotionblur.10.1145/2018323.201833465-70
