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 right equipment to achieve the access point cloud visit the segmentation method.
