Abstract
We propose to develop multiresolution representations and algorithms for synthetic terrain environments. They will be used for representing large terrain models as well dynamic and atmospheric simulations. Our ultimate goal is to increase the validity of the simulation by incorporating the multiple models at varying resolutions. We will use the OneSAF simulation Product Line Architecture Framework (PLAF) as a reference, and evaluate the use of static and dynamically generated multiresolution models within that framework. As part of Phase I, we developed multiresolution representations of terrain models using subdivision surfaces and also developed algorithms to generate static and dynamic levels-of-detail of terrain models. During Phase II, we would continue development of novel multiresolution representations and simulation algorithms for large terrains that consist of tens of millions of triangles. We would also focus on techniques to interactively visualize these models. Finally, we would use multiresolution representations and algorithms to speed-up LOS (line-of-sight) and collision detection queries on large terrains.
