In computer graphics, rendering engines are a type of middleware used for such a purpose. For real-time rendering, however, rendering engines often do not provide all functionality that is required, as in real-time, a certain degree of user interactivity aside from graphics is necessary, or can be the center of research. Furthermore, some modern research also explores interactivity with non-visual perceptual channels such as audio. Full game engines provide that functionality, however most state-of- the-art game engines are only available through expensive or exclusive licenses, or are completely unavailable for scientifc research.\r\n\r\nThis thesis presents the design, implementation and adaptation process of a state-of-the-art game engine that was tailored specifcally for research purposes. This game engine includes all the necessary components to build real-time-interactive computer graphics applications and has been used in several research projects such as the EU GameTools Project and the EU Crossmod Project.\r\n", "authors_et_al": false, "substitute": null, "main_image": { "description": "", "filetitle": "thumbnail", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 1024, "image_height": 768, "name": "CHIU-2008-PEN-thumbnail.bmp", "type": "image/x-ms-bmp", "size": 2359350, "path": "Publication:CHIU-2008-PEN", "url": "https://www.cg.tuwien.ac.at/research/publications/2008/CHIU-2008-PEN/CHIU-2008-PEN-thumbnail.bmp", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2008/CHIU-2008-PEN/CHIU-2008-PEN-thumbnail:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 733 ], "diploma_examina": "2008-06-10", "supervisor": [ 193 ], "research_areas": [], "keywords": [], "weblinks": [], "files": [ { "description": "", "filetitle": "thesis", "main_file": true, "use_in_gallery": false, "access": "public", "name": "CHIU-2008-PEN-thesis.pdf", "type": "application/pdf", "size": 19729894, "path": "Publication:CHIU-2008-PEN", "url": "https://www.cg.tuwien.ac.at/research/publications/2008/CHIU-2008-PEN/CHIU-2008-PEN-thesis.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2008/CHIU-2008-PEN/CHIU-2008-PEN-thesis:thumb{{size}}.png" }, { "description": "", "filetitle": "thumbnail", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 1024, "image_height": 768, "name": "CHIU-2008-PEN-thumbnail.bmp", "type": "image/x-ms-bmp", "size": 2359350, "path": "Publication:CHIU-2008-PEN", "url": "https://www.cg.tuwien.ac.at/research/publications/2008/CHIU-2008-PEN/CHIU-2008-PEN-thumbnail.bmp", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2008/CHIU-2008-PEN/CHIU-2008-PEN-thumbnail:thumb{{size}}.png" } ], "projects_workgroups": [ "GameTools" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2008/CHIU-2008-PEN/", "__class": "Publication" }, { "id": "CHARALAMBOS-2007-HLOD", "type_id": "inproceedings", "tu_id": null, "repositum_id": null, "title": "Optimized HLOD Refinement Driven by Hardware Occlusion Queries", "date": "2007-11", "abstract": "We present a new method for integrating hierarchical levels of detail (HLOD) with occlusion culling.

The traversal of the HLOD hierarchy is optimized by a new algorithm which uses spatial and temporal coherence of visibility. We predict the HLOD refinement condition for the current frame based on the results from the last frame. This allows an efficient update of the front of termination nodes as well as an efficient scheduling of hardware occlusion queries.
