The implementation of 2D Bezier Curve drawing using OpenGL. Add interactive functions: use mouse to draw control points add main menu for mouse control use keyboard to change the level of the Bezier curve. You can also drag the point to find a prefer

曲线和曲面Curves & Surfaces 实现一个简单的2D样条曲线编辑器。该编辑器应支持Bezier曲线和B样条曲线, 可以实现两种曲线的转换(仅对四个控制点的双三次样条曲线)。在你的曲线程序能工作后，将转到由这些曲线来产生曲面：旋转曲面和双三次Bezier 片.(Curves and surfaces Curves & Surfaces To achieve a simple 2D spline editor. The editor should support th
