Item Luminance-Preserving and Temporally Stable Daltonization(The Eurographics Association, 2023) Ebelin, Pontus; Crassin, Cyril; Denes, Gyorgy; Oskarsson, Magnus; Åström, Kalle; Akenine-Möller, Tomas; Babaei, Vahid; Skouras, MelinaWe propose a novel, real-time algorithm for recoloring images to improve the experience for a color vision deficient observer. The output is temporally stable and preserves luminance, the most important visual cue. It runs in 0.2 ms per frame on a GPU.Item Tight Bounding Boxes for Voxels and Bricks in a Signed Distance Field Ray Tracer(The Eurographics Association, 2023) Hansson-Söderlund, Herman; Akenine-Möller, Tomas; Babaei, Vahid; Skouras, MelinaWe present simple methods to compute tight axis-aligned bounding boxes for voxels and for bricks of voxels in a signed distance function renderer based on ray tracing. Our results show total frame time reductions of 20-31% in a real-time path tracer.Item Visualizing Errors in Rendered High Dynamic Range Images(The Eurographics Association, 2021) Andersson, Pontus; Nilsson, Jim; Shirley, Peter; Akenine-Möller, Tomas; Theisel, Holger and Wimmer, MichaelA new error metric targeting rendered high dynamic range images is presented. Our method computes a composite visualization over a number of low dynamic range error maps of exposure compensated and tone mapped image pairs with automatically computed, or manually provided, parameters. We argue that our new error maps predict errors substantially better than metrics previously used in rendering. Source code is released with the hope that our work can be a useful tool for future research.
