58 Large-Scale Battlefield Terrain Simplification and Fast Rendering
Download citation file:
Large-scale terrain rendering is an important application of virtual reality, However, the large data amount, low speed are always problems facing large terrain rendering, Therefore, how to improve the rendering speed and reduce the amount of data meanwhile maintain the original topography becomes a challenge. Considering the features and visualization requirements of large-scale battlefield terrain, a view-dependent, real-time and high quality terrain display method is presented in this paper. Using the Quadtree, Layered multi-resolution strategy, we partition the terrain into blocks and simplify triangular meshes inside the blocks, a simplified standard is given. Simulated operation shows that it has better...
