AE实现加载CAD格式的数据，以及对其进行转换格式，转换为SHP等格式，还有对其进行编辑等操作(AE spatial data editing functions, including generating points, generating lines, as well as delete, move elements such as fried operation)

说明：  mfc下绘出样条曲线，并根据样条曲线对其上的值进行差值。(mfc-spline curves plotted under and in accordance with spline curve on the value of their difference.)

画曲线图的c++例子，使用定时器去随机数的方式画图。(Draw the curve c example, use the timer to go the way of the random number drawing.)

说明：  单文档绘图测试程序。单文档绘图测试程序。(single document mapping test. Single document mapping test.)

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 )

服装CAD源代码，可以进行bspline的打断分割割，裁减操作，而且还可以解析shx字库，进行标注等。 (Garment CAD source code can be bspline split the interrupted cut cut operation, but also can resolve shx font marked.)

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)

分形几何是数学领域里新兴的课题,如果将图形的每个元素按某种规则进行变形,得到新的图形,以此类推,进行若干次变形后得到的图形就是分形图形。本程序实现分形图。(Fractal geometry is the mathematical field of emerging issues, if the graphics of each element according to certain rules of deformation, new graphics, and so on, to carry out a number of graphics after deformation is fractal graphics. This procedure realize fractals.)
