[29]. While direct illumination in static scenes is very common in video games and 3D applications, real-time global illumination methods supporting dynamic scenes and lights are still an active field of research.\r\n\r\nIn this work, a short general introduction to global illumination and spherical harmonics is presented as well as an overview of the state of the art methods in interactive global illumination for height fields.\r\n\r\nIn our method, visibility at each receiver point of a height field is determined by the visible horizon, which can be approximated efficiently using a multi-resolution sampling approach. Local light sources are represented by spherical lights and the incident radiance at receiver points is projected into the spherical harmonic basis. Hence, this method produces convincing shadows on dynamic height fields more efficiently than global illumination methods for general geometry.", "authors_et_al": false, "substitute": null, "main_image": { "description": "", "filetitle": "image2", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 1002, "image_height": 926, "name": "MeierStauffer-2013-iihf-image2.png", "type": "image/png", "size": 575122, "path": "Publication:MeierStauffer-2013-iihf", "url": "https://www.cg.tuwien.ac.at/research/publications/2013/MeierStauffer-2013-iihf/MeierStauffer-2013-iihf-image2.png", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2013/MeierStauffer-2013-iihf/MeierStauffer-2013-iihf-image2:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 776 ], "date_start": "2009-02-18", "matrikelnr": "9927153", "supervisor": [ 627, 193 ], "research_areas": [], "keywords": [ "Spherical Harmonics", "Height Fields", "Indirect Illumination" ], "weblinks": [], "files": [ { "description": "", "filetitle": "image1", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 2004, "image_height": 1852, "name": "MeierStauffer-2013-iihf-image1.jpg", "type": "image/jpeg", "size": 1148417, "path": "Publication:MeierStauffer-2013-iihf", "url": "https://www.cg.tuwien.ac.at/research/publications/2013/MeierStauffer-2013-iihf/MeierStauffer-2013-iihf-image1.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2013/MeierStauffer-2013-iihf/MeierStauffer-2013-iihf-image1:thumb{{size}}.png" }, { "description": "", "filetitle": "image2", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 1002, "image_height": 926, "name": "MeierStauffer-2013-iihf-image2.png", "type": "image/png", "size": 575122, "path": "Publication:MeierStauffer-2013-iihf", "url": "https://www.cg.tuwien.ac.at/research/publications/2013/MeierStauffer-2013-iihf/MeierStauffer-2013-iihf-image2.png", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2013/MeierStauffer-2013-iihf/MeierStauffer-2013-iihf-image2:thumb{{size}}.png" }, { "description": "", "filetitle": "poster", "main_file": true, "use_in_gallery": false, "access": "public", "name": "MeierStauffer-2013-iihf-poster.pdf", "type": "application/pdf", "size": 14797615, "path": "Publication:MeierStauffer-2013-iihf", "url": "https://www.cg.tuwien.ac.at/research/publications/2013/MeierStauffer-2013-iihf/MeierStauffer-2013-iihf-poster.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2013/MeierStauffer-2013-iihf/MeierStauffer-2013-iihf-poster:thumb{{size}}.png" }, { "description": "", "filetitle": "thesis", "main_file": true, "use_in_gallery": false, "access": "public", "name": "MeierStauffer-2013-iihf-thesis.pdf", "type": "application/pdf", "size": 36380158, "path": "Publication:MeierStauffer-2013-iihf", "url": "https://www.cg.tuwien.ac.at/research/publications/2013/MeierStauffer-2013-iihf/MeierStauffer-2013-iihf-thesis.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2013/MeierStauffer-2013-iihf/MeierStauffer-2013-iihf-thesis:thumb{{size}}.png" } ], "projects_workgroups": [ "Desiree" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2013/MeierStauffer-2013-iihf/", "__class": "Publication" }, { "id": "Auzinger_2013_AnaVis", "type_id": "journalpaper", "tu_id": null, "repositum_id": null, "title": "Analytic Visibility on the GPU", "date": "2013-05", "abstract": "This paper presents a parallel, implementation-friendly analytic visibility method for triangular meshes.

Recently, the acquisition of dynamic scenes at interactive frame rates has become feasible. A high-quality visualization of the resulting point cloud stream would require a per-frame reconstruction of object surfaces. Unfortunately, reconstruction computations are still too time-consuming to be applied interactively. In this paper we present a local surface reconstruction and visualization technique that provides interactive feedback for reasonably sized point clouds, while achieving high image quality. Our method is performed entirely on the GPU and in screen pace, exploiting the efficiency of the common rasterization pipeline. The approach is very general, as no assumption is made about point connectivity or sampling density. This naturally allows combining the outputs of multiple scanners in a single visualization, which is useful for many virtual and augmented reality applications.", "authors_et_al": false, "substitute": null, "main_image": { "description": null, "filetitle": "image", "main_file": false, "use_in_gallery": false, "access": "public", "image_width": 982, "image_height": 832, "name": "preiner_2012_AS-image.png", "type": "image/png", "size": 1318166, "path": "Publication:preiner_2012_AS", "url": "https://www.cg.tuwien.ac.at/research/publications/2012/preiner_2012_AS/preiner_2012_AS-image.png", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2012/preiner_2012_AS/preiner_2012_AS-image:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 799, 356, 193 ], "booktitle": "Proceedings of Eurographics Symposium on Parallel Graphics and Visualization", "date_from": "2012-05-13", "date_to": "2012-05-14", "editor": "H.

Hence simple texturing\r\nmapping is insufficient to produce such high geometric complexity.\r\nThis thesis proposes a cell-based approach to model and render repetitive fine\r\nscaled details with a high visual quality. The main idea of the precomputation is\r\nto decompose the object into a low frequent geometry (the general shape of the\r\nobject) and high frequent surface details. The high frequent surface details are\r\nrepresented by so-called cells tiled all over the object space. The precomputed\r\ncell-based object representation is displayed by a ray tracer providing correct\r\nparallax, occlusions and silhouettes.

These colors are diffused over the image plane, resulting in smooth color regions as well as sharp boundaries. In this paper, we introduce a new automatic diffusion curve coloring algorithm. We\r\nstart by defining a geometric heuristic for the maximum density of color control points along the image curves.\r\nFollowing this, we present a new algorithm to set the colors of these points so that the resulting diffused image is as close as possible to a source image in a least squares sense. We compare our coloring solution to the existing one which fails for textured regions, small features, and inaccurately placed curves.
