Abstract: According to the interpolating properties of Bézier curve,an improved basic function—BB basis function is presented.C1 preserving shape interpolating cubic spline curves are obtained by BB basis functions,and C1 preserving shape interpolating bi-cubic spline surfaces are generated.

摘要: 利用Bézier曲线的端点插值性质,得到了构造三次插值样条曲线曲面的一种改进的基函数——BB基函数。由BB基函数构造了C1保形三次插值样条曲线;构造了C1双三次插值样条曲面。
