OpenSceneGraph Quick Start Guide(The OpenSceneGraph the Quick Start Guide)

可以实现基本的绘图功能，画直线，矩形，圆椭圆。图形学作业(Can achieve the basic drawing functions and draw a straight line, rectangle, circle, ellipse. Graphics jobs)

手动绘制点，自动生成样条曲线，可以拖动修改点来修改样条曲线(Manually plotting points, automatically generated spline curves, you can drag the modified point to modify the spline)

绘图程序，可以自由绘制直线、矩形、圆、多边形，可以设置颜色和宽度，并且能够进行图元基本操作，如剪裁、缩放及填充功能。(Drawing program, free to draw lines, rectangles, circles, polygons, you can set the color and width, and can be primitive basic operations, such as cropping, scaling and filling functions.)

用四阶龙格-库塔法求系统在U单位阶跃输入下该系统的响应曲线(Using the four order Runge Kutta method to find the response curve )

VB编写的画图板，使用方便可以帮助代码学习。。(VB prepared the drawing board, easy to use can help the code to learn. .)

画图 可保存读取 Bresenham算法 中点画线法 数值微分法（DDA）(Paint to save the Bresenham algorithm were dotted line is read the numerical differentiation Act (DDA))

该程序实现圆拟合，对学习圆拟合有一定帮助。(circle fit based on VC++)

这是一个简单的画圆功能，主要让用户学会如何利用Windows提供的画图工具，用户单击鼠标右键则会弹出对话框选择线宽，在菜单上也设计了圆的颜色选择菜单。(This is a simple function of the Circle. mainly for users to learn how to use Windows for the drawing tools, Users right-click pop-up dialog box will be chosen linewidth, the menu also designed a circular color choice menu.)

说明：  函数绘图程序 VB 编写 可以绘制初高中 函数图像 支持颜色，精度修改 鼠标执针定位(VB function drawing program to prepare middle and high school mapping function can support color images, the accuracy of needle positioning modified mouse bailiff)
