摘要
建筑物三维模型的构建是数字城市三维可视化的主要内容,采用成熟的商业软件可以提高开发速度,但同时带来价格昂贵、移植性差、硬件要求高等缺点。采用基于二维地理数据库或摄影影像提取建筑物框架,结合OpenGL丰富强大的三维绘图功能,可以快速的实现对建筑物的三维建模,同时避免了使用商业软件所带来的诸多困难。
The construction of 3D building modeling is a main part of the 3D visualization of a digital city, which adopts the well - develpoed commercial software to increase development speed, and as well accompanies the disagvantages such as high price, poor transplant character and high demand for hardware and so on. Based on the 2D geographical database or the image to extract building frameworks, and the strong functions of 3D drawing of OpenDL, the author suggests that the rapid 3D building modeling could be achieved and at the same time the difficulties caused by commercial softwares could be avoided.
