Abstract
Real-time inspection and visualization of huge terrain models is a promising topic with many potential applications. Interactive rendering of planet-size, photo-textured digital elevation models hosted on remote servers is a challenging problem, requiring a careful management of the data. Typical user requirements include the access to as many accessible datasets as possible, scalable algorithms and a client—server architecture. Besides efficient handling of out-of-core gigantic models, our work has been specially focused to urban rendering and to video mapping. Our technique for the visualization of large scale urban models is based on the image-based rendering of a hierarchical collection of relief-mapped polygons. Moreover, real-time video mapping of captured video from flying cameras onto the digital terrain model can be a powerful tool for environmental security and protection.
