曲线生成 meaning in Chinese
curve generation
Examples
- As an application of the algorithm and the properties , some examples are given
作为对曲线生成算法和性质以及插值方法的应用，最后给出了一些图形实例。 - The paper expounds the algorithms of generating quadratic curve . using quadratic curve and cubic bezier curve enforces the smooth of curves
论文阐述了几种二次曲线生成算法；说明如何应用二次曲线和三次bezier曲线拟合改善曲线的光滑性。 - The thesis also explains how to design the function models , ( such as communication model , curve building model and control arithmetic model etc . ) in the software of the controller . the method of corresponding these models was also illuminated
阐述了adcm控制器的软件设计；阐述了各个功能模块(如通讯模块、曲线生成模块、控制算法模块等)的实现及它们之间协调工作的方法。 - Since pixel - level contrapose pixel coordinate , trigonometric function must be used to translate polar coordinates to pixel coordinate when the curve is described by polar coordinate . so research is very little on algorithms for generating this sort of curve by now
由于逐点是针对象素坐标系而言，而对极坐标系下描述的曲线，在转换到象素坐标系时要用到三角函数运算，因此目前很少提到对极坐标曲线生成算法的研究。 - Paper [ 76 ] provides a integer algorithm for rasterizing free curves , we need change the curve form to implicit function form , then use curve ' s positive - negative property to draw , but we ca n ' t use this algorithm when curve ' s degree is higher than 3 and this algorithm ca n ' t avoid using multiplication ; paper [ 77 ] provides a new generating algorithm , this algorithm can draw bezier very well , but for b - spline curve , we need use convert them into bernstein base form . because this process spends a lot of time , this algorithm has not a good speed and effect for rendering rational b - spline curve
现在经常采用的算法也是基于几何的算法(即线式生成算法)和基于像素的算法(点式生成算法) ;文献78 ]提供了一种有理参数曲线的快速逐点生成算法，该算法对有理b吮ier曲线的绘制，能起到很好的作用，但是对于有理b样条曲线，必须先通过多项式的代数基与bemstein基间的变换矩阵，把原式用bemstein基表示，这一过程由于计算量大，降低了曲线生成的速度和效率
