摘要
马鞍面上构造一种带有形状因子的有理参数样条曲线,该样条曲线具有较好的几何特性,并且可以作升阶和降阶处理。分析其端点性质,便于拼接成光滑曲线,如果选取合适的形状因子,可以使得曲线连接成G2连续。
A parametric spline curve with a shape factor is produced on a hyperbolic paraboloid,which possesses fine geometrical properties.This spline can be done with degree reduction and elevation.The properties of two endpoints were alaysed,that enables us to attach a fairly curve.A G2-continuity curve can be attached by those spline if we use a group of determined shape factors.
