20.500.12556/RUL-148270 Combined volume and surface rendering with global illumination caching We present a combined volume and surface rendering technique with global illumination caching. Our approach uses volumetric path tracing to compute the global illumination volume and local shading models for rendering the isosurface. By joining both visualization approaches, we have enhanced the display and illumination of the surfaces while preserving physically realistic illumination of the participating media. To achieve real-time performance and avoid recomputing the image when the camera view changes, we compute the global illumination volume incrementally and defer the projection to a later step. We evaluated our technique by comparing different local shading models for isosurface rendering with the result of full volumetric path tracing and with the non-caching variant of our technique. Results show that the caching and non-caching variants perform comparably well, while the caching variant has the added benefit of being camera-view-independent. Additionally, we show that our approach emphasizes the surfaces within volumes better than volumetric path tracing. irradiance caching global illumination volumetric data medpomnjenje obsevanja globalna osvetlitev volumetrični podatki true false true Angleški jezik Slovenski jezik Članek v reviji 2023-08-09 09:13:10 2023-08-09 09:13:13 2024-04-09 03:46:00 0000-00-00 00:00:00 2024 0 0 Str. 2491–2503 iss. 4 Vol. 40 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 004 0178-2789 10.1007/s00371-023-02932-9 157669379 s00371-023-02932-9.pdf s00371-023-02932-9.pdf 1 E79DE12216BBB42EDBFF87E3D0BF6F08 18f4ff3c0c6a3580ecd0a7ea050615b04c8f48f1d8383fda33fab0ac67e50200 3fcf336e-f57b-11ee-937a-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=182560 https://link.springer.com/article/10.1007/s00371-023-02932-9 1 3765e4a1-3684-11ee-aeaf-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=172343 Fakulteta za računalništvo in informatiko 0 0 0
