Our results show total frame time reductions of 20-31% in a real-time path tracer.Attribution 4.0 International LicenseCCS Concepts: Computing methodologies → Ray tracing; Volumetric modelsComputing methodologies → Ray tracingVolumetric modelsTight Bounding Boxes for Voxels and Bricks in a Signed Distance Field Ray Tracer10.2312/egs.2023101353-564 pages
