The geometrical reconstruction functions were realized with the standard functions of the OpenGL that is one kind of graphics standard and was included in this system, the accessorial control functions were also realized at the same time.

• 在系统中引入OpenGL图形标准,通过OpenGL的函数实现OBJ文件中的三维模型几何重建,同时实现三维模型的各种辅助控制功能。
