介绍用OpenGL实现点云处理的三维变换，我们可以通过API函数 CreateFile 获得设备句柄，再用API函数 DeviceIoControl 来实现对设备的访问获取点云的分割方法。-introduces OpenGL point cloud processing of 3D transformation, we can pass CreateFile API access to equipment handle, reuse API function DeviceIoControl ri

这段代码功能是显示VRML格式文件，采用Opengl显示列表，平滑分割3D三角形网格-This code function is shown VRML format used Opengl display list, Smoothing segmentation 3 D triangular mesh

The segmentation of structure from 2D and 3D images is an important rst step in analyzing medical data. For example, it is necessary to segment the brain in an MR image, before it can be rendered in 3D for visualization purposes. Segmentation
