摘要
分析了基于VRML的三维地形可视化实现技术,依照VRML语法扩展了适合三维地形网络表达的VRML原型节点,解决了如何使三维大规模地形数据直接进入VRML世界、高精度数学运算和实时交互漫游的难点问题.
The methods to realize threedimensional terrain visualization are discussed, and the proto node definition suitable for threedimensional terrain visualization extended according to virtual reality modeling language (VRML). The method solves the problem of the use of largescale data directly in the VRML environment, calculation with high precision and realtime wandering.
