传统的二维构造图难于直观地描述地质构造的空间形态。综合利用VB、VC和OPENGL环境设计的盆地构造图三维可视化系统将构造图上涉及的要素分成点、线、面、区等不同类型，每个类型数据又都由空间数据和属性数据两部分组成，并用数据库方式管理这些数据。系统除了可将各构造要素以三维方式显示外，还可以利用测井数据和剖面图恢复三维地层；同时允许用户与屏幕图形进行交互，从而实现对图形的切割操作。显示成果可以以栅格图形或AVI录像形式输出。通过几个用该系统输出的三维构造图的实例说明该系统基本能满足盆地构造图三维显示的需要。

It is difficult for conventional 2D tectonic map This paper introduces one 3 D visual system of to depict directly the spatial shape of geological structure. basin tectonic map based on the integrated environment of VB, VC and OPENGL. The factors related to the geological tectonic was divided into different types, such as point, line, plane and region. Each type of data includes two parts ： spatial data and properties data. All the data are managed through database. Besides displaying the geological tectonic factors three dimensionally, 3D strata can be restored by means of well data and section map. In the same time, the graph can be cut through interactive operation between user and screen. Lastly, the achievements can be outputted by way of grid graph or AVI. The examples of 3D tectonic map from this system illustrate that it can fulfill the basic display of basin tectonic map three dimensionally.
