说明：  三次B样条,程序中有部分说明,可以自由在其中进行扩展设计其它类似样条程序.(cubic B-spline, some procedures that can be carried out in one free expansion design similar kind of procedure.)

PSCAD Simulation for Lines

绘画出三阶的贝塞尔曲线, 求出曲线上各点的曲率和半径,可用于弯道设计(Drawing out the order of the Bezier curve, find the points on the curve and radius of curvature, can be used for curve design)

非常强大的光学仿真软件，可以模拟光线的反射、折射、以及绘制各种像差曲线例如球差、色差。(Very powerful optical simulation software can simulate light reflection, refraction, and the mapping of various aberrations such as spherical aberration curves, color)

已知zernike多项式的系数大小，画出相应图形。(Given the Zernike term, draw the corresponding figure)

说明：  c#语言 Devexpress设计的界面。 基于ArcEngine的基础设计 包括：打开、保存、另存地图文档， 地图的放大、缩小、平移等， 图层的移动、删除、显示属性表等， 绘制图形:画线、画面、画圆、画矩形等， 空间数据的导入等。(c# language Devexpress design interface. ArcEngine based on the design include: Open, Save, Save the map document, map zoom, pan, etc., layers move, delete, display the property sheet, etc., draw the graph: draw lines, pictures, circle, rectangle and other spatial data import and so on.)

该程序是用C 语言编写的图形学中的贝济尔曲线,简单实用易懂(this program is Bezier program about computer picture,wich is degn by c.)

画图程序,你可以参考上面的代码编写绘制直线，圆，椭圆和矩形，此外，还可以绘制文字和调节颜色(Drawing program,you can draw line,rectangle,ellipse,triangle,and other things,also,words,and color you can sellect)

说明：  用VC++编写，MFC文档框架，是一个简易的画图小程序，在文档界面上画图(With VC++ Prepared, MFC framework document is a simple drawing of small procedures, the document interface drawing)
