--- res: bibo_abstract: - Many 3D scenes (e.g. generated from CAD data) are composed of a multitude of objects that are nested in each other. A showroom, for instance, may contain multiple cars and every car has a gearbox with many gearwheels located inside. Because the objects occlude each other, only few are visible from outside. We present a new technique, Spherical Visibility Sampling (SVS), for real-time 3D rendering of such -- possibly highly complex -- scenes. SVS exploits the occlusion and annotates hierarchically structured objects with directional visibility information in a preprocessing step. For different directions, the directional visibility encodes which objects of a scene's region are visible from the outside of the regions' enclosing bounding sphere. Since there is no need to store a separate view space subdivision as in most techniques based on preprocessed visibility, a small memory footprint is achieved. Using the directional visibility information for an interactive walkthrough, the potentially visible objects can be retrieved very efficiently without the need for further visibility tests. Our evaluation shows that using SVS allows to preprocess complex 3D scenes fast and to visualize them in real time (e.g. a Power Plant model and five animated Boeing 777 models with billions of triangles). Because SVS does not require hardware support for occlusion culling during rendering, it is even applicable for rendering large scenes on mobile devices.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Benjamin foaf_name: Eikel, Benjamin foaf_surname: Eikel - foaf_Person: foaf_givenName: Claudius foaf_name: Jähn, Claudius foaf_surname: Jähn - foaf_Person: foaf_givenName: Matthias foaf_name: Fischer, Matthias foaf_surname: Fischer foaf_workInfoHomepage: http://www.librecat.org/personId=146 - foaf_Person: foaf_givenName: Friedhelm foaf_name: Meyer auf der Heide, Friedhelm foaf_surname: Meyer auf der Heide foaf_workInfoHomepage: http://www.librecat.org/personId=15523 bibo_doi: 10.1111/cgf.12150 bibo_issue: '4' bibo_volume: 32 dct_date: 2013^xs_gYear dct_isPartOf: - http://id.crossref.org/issn/0167-7055 dct_language: eng dct_title: Spherical Visibility Sampling@ ...
