The new model is as simple as the well-known Phong model, but eliminates its disadvantages. It gives a good visual approximation for many practical materials: coated metals, plastics, ceramics, retro-reflective paints, anisotropic and retro-reflective materials, etc. Because of its illustrative properties it can be used easily in most commercial software and because of its low computational cost it is practical for virtual reality. The model is based on a special basic BRDF definition, which meets the requirements of reciprocity and of energy conservation. Then a class of BRDFs is constructed from this basic BRDF with different ent weight functions, The definition of such weight functions requires the user to specify the profile of the highlights,from which the weight function is obtained by derivation. It is also demonstrated how importance sampling can be used with the new BRDFs.}, year = {1999}, eissn = {1467-8659}, pages = {249-265}, orcid-numbers = {Szirmay-Kalos, László/0000-0002-8523-2315} } @article{MTMT:2612467, title = {Stochastic iteration for non-diffuse global illumination}, url = {https://m2.mtmt.hu/api/publication/2612467}, author = {Szirmay-Kalos, László}, doi = {10.1111/1467-8659.00344}, journal-iso = {COMPUT GRAPH FORUM}, journal = {COMPUTER GRAPHICS FORUM}, volume = {18}, unique-id = {2612467}, issn = {0167-7055}, abstract = {This paper presents a single-pass, view-dependent method to solve the rendering equation, using a stochastic iterational scheme where the transport operator is selected randomly in each it ration. The requirements of convergence are given for the general case. To demonstrate the basic idea a very simple, continuous random transport operator is examined, which gives back the light tracing algorithm incorporating Russian roulette. Then, a new mixed continuous and finite-element based iteration method is proposed, which uses ray-bundles to transfer the radiance in a single random direction. The resulting algorithm is fast, it provides initial results in seconds and accurate solutions in minutes and does not suffer from the error accumulation problem and the high memory demand of other finite-element and hierarchical approaches.}, year = {1999}, eissn = {1467-8659}, pages = {233-244}, orcid-numbers = {Szirmay-Kalos, László/0000-0002-8523-2315} } @book{MTMT:1063936, title = {Monte-Carlo Methods in Global Illumination}, url = {https://m2.mtmt.hu/api/publication/1063936}, author = {Szirmay-Kalos, László}, publisher = {TU Wien}, unique-id = {1063936}, year = {1999}, orcid-numbers = {Szirmay-Kalos, László/0000-0002-8523-2315} } @article{MTMT:2606380, title = {Interactive Volume Rotation}, url = {https://m2.mtmt.hu/api/publication/2606380}, author = {Csébfalvi, Balázs and Szirmay-Kalos, László}, journal-iso = {MACH GRAPH VIS}, journal = {MACHINE GRAPHICS AND VISION}, volume = {7}, unique-id = {2606380}, issn = {1230-0535}, year = {1998}, pages = {793-806}, orcid-numbers = {Szirmay-Kalos, László/0000-0002-8523-2315} } @techreport{MTMT:2616703, title = {New Simple Reflectance Models for Metals and other Specular Materials}, url = {https://m2.mtmt.hu/api/publication/2616703}, author = {Neumann, László and Neumann, Attila and Szirmay-Kalos, László}, unique-id = {2616703}, year = {1998}, pages = {1-16}, orcid-numbers = {Szirmay-Kalos, László/0000-0002-8523-2315} } @inproceedings{MTMT:2616690, title = {Fast Opacity Control of Volumetric CT Data}, url = {https://m2.mtmt.hu/api/publication/2616690}, author = {Csébfalvi, Balázs and Szirmay-Kalos, László and Márton, Gábor}, booktitle = {WSCG '97: THE FIFTH INTERNATIONAL CONFERENCE IN CENTRAL EUROPE ON COMPUTER GRAPHICS AND VISUALIZATION '97: CONFERENCE PROCEEDINGS, VOL 1-4}, unique-id = {2616690}, year = {1997}, pages = {79-87}, orcid-numbers = {Szirmay-Kalos, László/0000-0002-8523-2315} } @inproceedings{MTMT:2616696, title = {Radiosity Algorithms running in Sub-quadratic Time}, url = {https://m2.mtmt.hu/api/publication/2616696}, author = {Szirmay-Kalos, László and Fóris, Tibor}, booktitle = {WSCG '97: THE FIFTH INTERNATIONAL CONFERENCE IN CENTRAL EUROPE ON COMPUTER GRAPHICS AND VISUALIZATION '97: CONFERENCE PROCEEDINGS, VOL 1-4}, unique-id = {2616696}, year = {1997}, pages = {552-561}, orcid-numbers = {Szirmay-Kalos, László/0000-0002-8523-2315} } @book{MTMT:2612493, title = {Theory of Three Dimensional Computer Graphics}, url = {https://m2.mtmt.hu/api/publication/2612493}, isbn = {9630569116}, author = {Szirmay-Kalos, László and Márton, Gábor and Dobos, Balázs and Horváth, Tamás and Risztics, Péter and Kovács, Endre}, editor = {Szirmay-Kalos, László}, publisher = {Akadémiai Kiadó Zrt.}, unique-id = {2612493}, year = {1995}, orcid-numbers = {Szirmay-Kalos, László/0000-0002-8523-2315} }
