基于OpenGL的源码，允许用户用鼠标选点，对三维物体进行变形-OpenGL-based source code that allows users to use the mouse to the choice of site, the deformation of three-dimensional objects

使用OpenGL绘制B样曲线，实现鼠标右键在屏幕中选点，左键可拖动点，三次，四点确定一条曲线-B-spline curves using OpenGL rendering to achieve the right mouse button on the screen selected points, left draggable points, three times, four points determine a curve

ＯｐｅｎＧＬ环境下读入３Ｄ点云，任意角度下鼠标对点云进行框选。(In the OpenGL environment, read the 3D point cloud, and at any angle the mouse can box the point cloud.)

具备点云数据的显示，在显示界面通过鼠标选择需要点并保存。(With the display of point cloud data, the display interface needs to be selected and saved through mouse selection.)
