OpenGL实现B样条曲线曲面，可看控制点，基函数，并且阶次可以自动升降，并添加纹理，光照等模式-OpenGL to achieve B-spline curves and surfaces, if we look at control points, basis functions, and can automatically order take-off and landing, and add texture, light, such as model

利用B spline和Catmull-rom spline实现物体的移动，旋转由四元数和欧拉角实现。 需要已配置opengl-using B Spline and catmull-rom spline implement the interpolation of object. Rotation are applied by Quaternion and Euler Angle. Please see the implementation video: https://www.youtu

b样条曲面 有灯光、鼠标球旋转等功能 opengl 可调整控制点-b-spline surface lighting, mouse ball rotation opengl adjustable control points

本人早期用易语言做的OpenGL+B样条练习，根据鼠标单击点反求控制顶点，适合初学图形编程学习。-I spent the early easy language to do OpenGL+B spline exercises, according to the mouse click point reverse control vertices, suitable for beginners to learn graphical programming.
