| Abstract: | In the multi-resolution terrain modeling,progressive mesh can store mesh information efficiently,and control the mesh 's level-of-detail conveniently.In this paper,the authors make use of the Direct3D 3-dimensional graphics lib,give a method to create multi-resolution terrain model based on the progressive mesh.This method can control the simplification course of the mesh conveniently and has the ability to display quickly.Moreover,it can maintain the original mesh's geometrical characteristics very well. |
