三维骨架运动数据bvh的读取，显示,基于B样条的路径编辑，运动编辑，多种骨架插值算法（四元数+B样条插值）-3D skeleton movement data bvh read, display, based on B-spline path of the editors, sports editors, Skeleton various interpolation algorithm (Quaternion B-spline interpolation)

这是一个三次样条插值的.m程序 输入的是一个二维数组A(Nx2) 插值方法为: S(x) = A(J) + B(J)*( x - x(J) ) + C(J)*( x - x(J) )**2 +D(J) * ( x - x(J) )**3 for x(J) <= x < x(J + 1)

均匀三次B样条曲线插值，定义插值函数，B样条拟合三维曲面(Interpolation of B spline curves)

三维b样条插值matlab代码，拟合效果较好(3-D B-spline interpolation matlab code)
