b样条曲线，有控制点的求法，还有用OPENGL显示算法-b-spline curves, the control point for France, there is use OpenGL display algorithm

How to Simulate A Ponytail - The Sample App This is a very simple Lagrange Multiplier constrained dynamics simulator to accompany my articles and lectures on How to Simulate a Ponytail. For more information, see http://chrishecker.com/H

双三次B样条曲面案例的OpenGL编程，可绘制出曲面以及多边形-Bi-cubic B-spline surface case OpenGL programming, surfaces and polygons can be drawn out
