摘要
利用二次均匀B样条曲线的端点性质,导出了构造插值二次均匀B样条曲线曲面的一种新的基函数―BB基函数。由BB基函数构造了C1保形插值二次均匀B样条曲线,构造了C1双二次均匀B样条插值曲面。
According to the endpoint properties of quadratic uniform B-spline curve,a new basic function-BB basis function is derived.C1preserving shape interpolating quadratic uniform B-spline curves are obtained by BB basis functions,and C1 interpolating biquadratic uniform B-spline surfaces are constructed.
