Based on the characteristics of the geological exploring data , a method for establishing data model was presented , in which the triangle network was combined with the quadrangle network . at last , the geologic maps needed for geological research were drawn through the gdi ( graphics device interface ) and the 3d visualization system model was established for stratumtous geological body . base on the achievments mentioned above , a software system was developed which can be used independently without relying on any software platform 文中首先介绍了可视化技术以及地质制图技术的发展，然后对地质构造可视化模型进行了研究，根据地质测量数据的特点，提出了三角形网和四边形网相结合的数据建模方法，最后通过图形接口绘制了地质研究所需的地质图件，构建了层状地质体三维可视化系统模型，并开发出了可以独立于任何软件平台使用的地质三维可视化软件系统。
