Examples
- New method for auto - generating curve contour character
一种新的曲线字库自动生成方法 - In the second chapter , a class of polynomial blending functions of degree n + 1 is presented . based on the functions , we present polynomial curves with some shape parameters . the generated curves are similar with the degree n bezier curves
第二章给出一类n + 1次多项式调配函数,并由此构造了带形状参数的多项式曲线,生成曲线具有与n次b zier曲线类似的几何性质。 - There are two mainly method for surface rebuild , one is based on three angular bezier surface , the other is b - spline or nurbs surface . the property of b - spline and nurbs curve is introduced and how to generate curve and surface with interpolation is studied
对基于三角bezier曲面和b样条或nurbs曲面的曲面重构进行了论述,介绍了b样条和nurbs曲线曲面特点并对用插值法生成曲线曲面进行了研究。 - In chapter 4 , we research a way how to generate curve by discrete points . the way uses several low - order bezier curve to substitute one high - order bezier curve in order to avoid computing high - order negative matrix . the curve produced by this way has good smoothness
第四章对由离散点构建曲线进行了研究,绕过高阶矩阵求逆,把由k个低阶的bezier曲线拼合产生的复合曲线来代替单一的高阶bezier曲线,并保证曲线之间的光滑过渡。 - Another algorithm is based on pixels : sample many points along the curve , round them to the nearest integer and set each pixel the computed point falls in . although this algorithm uses integer arithmetic , it provides the smooth curve possible at the expense of computation time as many points have to be computed to ensure that no gaps are created along the curve . furthermore these two algorithms we mentioned above is appropriate for low degree parametric curves , for high degree parametric curves , we usually approach them by using low degree rational parametric curves , the generating curve ' s fairness property is not very good
我们知道当节点矢量的两端节点均为k重节点且无内节点时, b样条基函数退化为bemstein多项式,因此该生成算法还可推广到b能ier曲线中,具有广泛的应用价值、同样地,在cad和cagd中,有理b样条曲线,特别是非均匀有理b样条曲线( nurbs )已经成为曲线曲面设计中最广为流行的技术,然而对这些曲线目前也尚无很好的曲线生成算法,因此有理b样条曲线的生成算法无疑有着更重要的意义
