Real-Time Walkthroughs of Serious Synthetic Environments

The goal - so far not entirely realized - of synthetic environments is toprovide a realistic experience for their users. In particular, theseenvironments can be used for active collaboration on engineering designsand medical applications. This project attacks some of the most importantoutstanding problems in the field of real-time synthetic environments:1) Develop a scalable system to achieve real-time walkthrough of very largeCAD models with high-accuracy rendering of spatial arrangements.2) Develop parallel rendering algorithms that take into account emerginggraphics architectures with multiple graphics pipelines and general-purposeprocessors.3) Develop incremental algorithms to allow interactive updates to largedynamic environments, allowing objects to be moved, added, and removed inrealistic manners.Among the algorithms that the project will explore are visibility culling,multi-resolution methods, model simplification, image-based rendering,3-Dimage warping, multi-pass rendering, and efficient updates for modelhierarchies, occlusion databases, and level-of-detail generation. Theseadvances will be tested on real-world models, including a 13million-element polygonal model of an electric generating station.
