【摘要】 提出一种基于B样条曲线降阶的三次B样条曲线骨架卷积曲面造型方法.首先通过顶点扰动降阶方法把三次B样条曲线骨架(C1连续)降阶为C1连续的二次B样条,然后应用二次B样条曲线骨架的卷积曲面势函数计算方法得到三次B样条曲线骨架的势函数.更多还原

【Abstract】 In this paper we propose a new cubic B-spline skeleton convolution surface modeling method based on curve degree reduction.We first reduce the cubic B-spline curve with C~1 continuity to C~1quadratic B-splines using constrained optimization methods,and then sum the potentials of each quadratic B-spline skeleton to obtain the potential of the whole cubic B-spline skeleton.更多还原
