摘要：The 3D modeling system of gravity dam is established based on the secondary development of ArcGis Engine and AutoCAD and according to VB6.0.In the system,the terrain modeling method,which is based on TIN created by terrain data,is used to realize the terrain modeling,and the graphical modeling method,which uses 2D graphics to re-store 3D model,is adopted to build dam model.Based on the advantage of ArcGis,the geographic information of hydro junction is also taken into consideration in modeling,and Geodatabase is built to store the massive information above,so as to implement the functions of 3D analysis and query.The examples demonstrate that the system is versatile,convenient and efficient.
