【摘要】 由非均匀有理Ｂ样条（ＮＵＲＢＳ）曲线曲面给定边界条件（边界值或者再加上边界导矢），用偏微分方程（ＰＤＥ）来构造曲面，以参数‘ａ’控制其整体形状，本文分析其思路原理及过程，并列举了在ＣＡＤ上的应用，最后分析了优缺点。更多还原

【Abstract】 In terms of boundury conditions defined by NURBS surfaces, a method of using PDE to construct shape adjustable surfaces is discussed. The shape is controlled by some parameter ’a’. This paper analysis the principles and procedures of the method and explains the applications in CAD by several examples. Finally, its advantages and disadvantages are listed.更多还原
