| 摘 要： | 按照曲线复杂度定义，首先对复杂度最高的曲线进行最精简逼近，然后在一定控制精度下对轮廓线依据曲率特征进行重采样；对所有曲线进行基于曲率特征的重采样，并对曲线采用插值方法统一轮廓点数量；采用平均化的方法获得U，V方向的公共节点矢量，并通过插值的方法得到体积较小的曲面造型．避开了生成相容性轮廓线的过程，提高了曲面重构的效率．

| Abstract: | Rectangular bicubic non uniform B spline patches are exploited to fit the sampled data points of femoral Knot vectors for constructing the longitudinal and transverse boundaries are defined as a compromised average of all section curves in each direction respectively Spacing of knots is assigned conforming to the local curvature of femoral surface, being shorter at ridge area of large curvature and longer at flat area |
