摘要: 针对目前NURBS模型的局限性问题,在对T-Bézier基函数及曲线端点特性分析的基础上,提出了k次T-Bézier基函数的表达式,通过重新参数化使其参数区间范围规范为[0,1],给出了椭圆弧和心脏线的T-Bézier表示,并给出T-Bézier曲线间G1拼接的几何条件,所得结论具有明确的几何意义,能够较好的应用于曲面造型中。
关键词: T-Bézier, 基函数, 拼接, 曲面造型
Abstract: For the localization of NURBS, presents K-Degree T-Bezier basis function and reparametrizes it on the interval [0,1],representation of ellipse and cardioid and G1 condition of T-Bézier curves based on the analysis of T-Bézier basis functions and terminal properties. The results have definite geometric meanings that are useful for surface modeling.
Key words: T-Bézier, basis function, continuity, surface modeling
