ABSTRACT
To improve the visualization of large 3D landscapes and city models in a network environment, the authors use two different types of hierarchical level-of-detail models for terrain and groups of buildings. They also leverage the models to implement progressive streaming in both client-server and peer-to-peer network architectures.
INDEX TERMS
Network-based 3D visualization, networked virtual environments, level of detail, peer-to-peer overlays, 3D adaptive streaming, multi-resolution modeling
