Because there exists a high randomness an easier weighted method is used to establish Grid-format data to approximately describe 3-D space topography,3-D topography is constructed for Grid-format data by using OpenGL technology,and a free transform of the space curved surface is realized,including parallel move,zoom,circumgyrate.

由于存在很大的随机性,采用较为简单的加权方法来建立规则网格Grid格式数据体对三维空间地形进行近似描述,利用OpenGL技术构造Grid数据体三维地形,并对构造出的三维空间曲面进行平移、缩放、旋转等自由变换,提供最多6个切面对三维空间曲面进行任意切割的算法,结合地质演化需要,利用双缓存技术实现了地质要素三维曲面动态演化过程。
