小型交互式图形系统，由Turbo C2.0编写，实现了计算机图形学中的多边形裁减；多边形旋转，平移，缩放；Bezier曲线；B样条曲线；中点圆；等算法。并实现橡皮筋直线，橡皮筋矩形画法，采用鼠标与用户交互，十分好用。这是南京航空航天大学计算机专业计算机图形学课程设计作业，母校的小弟小妹们或许能作为作业的参考。-Small interactive graphics system, prepared by the Turbo C2.0 achieved in computer graphics Polygon reduction　polygon rotation, translation, scaling　Bezier curves　B-spline curve　the mid-point circle　such algorithm. Rubber band and to achieve a straight line, rubber band rectangle drawing method, using the mouse with the user interaction is very easy to use. This is the Nanjing University of Aeronautics and Astronautics computer professional computer graphics course design work, his alma mater, the younger girl who might be able to work as a reference.
