Abstract

One of challenges in large-scale terrain visualization is to rapidly build numerous 3D terrain models with crucial geomorphic features and adequate simplicity. This paper proposes a solution involving a terrain pyramid modeling method based on parallel programming that gives a boost to modeling speed of DEM/texture pyramid, and an effective approach to generate meshes from DEM by combining the VIP algorithm with regular square grids. In the pyramid modeling method, different input data are loaded by multiple processes simultaneously into a shared memory so that the parent process is capable of performing a parallel aggregation algorithm in GPU subsequently. Moreover, a speedup strategy is adopted to reduce running time of the VIP algorithm by limiting its input to centers of regular grids partitioning the input DEM. Experimental results successfully validate the two methods presented in the paper.
