摘要
给出了一组含有参数λ的三次三角基函数,分析了此基函数的性质。基于该组基定义了带形状参数的三角曲线,该曲线不仅具有二次T-Bézier曲线的性质,而且具有形状可调性和更好的逼近性。参数λ有明确的几何意义。最后还讨论了两段曲线的G2拼接条件。
A set of triangle basis function which implies parameter λ, was proposed. Its properties were analyzed and a triangle curve with a shape parameter was defined based on the basis. The curve not only has properties of T-Bezier curve, but also shape adiustability and better approximability. Finally,G^2connection conditions of two curves was discussed.
