A view-dependent multiresolution modeling combined with a dynamic loading technique for large-scaled terrain model visualization is proposed. With multiresolution modeling, a terrain model is constructed as a multiresolution structures and then a proper structure is selected for browsing to achieve the real-time visualization. The view-dependent framework is used to selectively refine or coarsen the multiresolution model based on the view parameters to further improve the visualization performance. With the dynamic loading, we partition a large-scaled terrain model into blocks and then dynamically load the necessary terrain blocks for browsing. In addition, two improvements on the proposed approach are also addressed, which are: (i) detecting and resolving the "fold-back" problems and (ii) solving the boundary matching problems for adjacent terrain blocks in dynamic loading.
