Multi-Resolution Representations and Interactive Visualization of Large Terrain Models

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. Moreover, we will develop novel multiresolution reprsentations of large scattered datasets and use them for interactive display as part of Phase I. We also propose a Phase I option to develop efficient line-of-sight (LOS) computations algorithms based on the multiresolution representations for large terrain environments. If successful, the proposed representations and algorithms can significantly improve the performance of OneSAF simulation framework.
