| 摘 要： | 由于建立三维图形数据量很大,大多需要借助价格昂贵的专业图形加速卡或图形工作站.基于OpenGL在PC机上实现了三维形体的重构过程.该过程首先对二维断层数据进行建模,然后生成形体的线框图,并对生成的线框图进行优化,最后使用最短对角线法进行三维立体表面的重构.该方法基于OpenGL,不需要专用的图形工作站,生成速度快,而且还可以旋转、缩放观察所生成的立体表面不同位置的情形,取得了较好的效果.

| Abstract: | Since the data of three-dimensional graphics is very large,they most need help from expensive professional graphics accelerator or graphics work station.In this paper,a three-dimensional shape reconstruction process is achieved based on OpenGL in PC.First,two-dimensional tomography data is modeled,then the shape frame diagram is generated,and the resulting frame diagram is also optimized,at last,the three-dimensional shape is reconstructed using the shortest diagonal method.The method is based on OpenGL,it ... |
