该程序可以绘制出扇形，并且带有黑色边框。(The program can draw out the fan, and with a black border.)

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.)

说明：  一个模拟cad画图的程序,实现了直线,椭圆,圆,矩形等图形的画法.需要安装后才能查看源码和相关文档(cad drawing a simulation procedures to achieve a straight line, oval, round, rectangular and other graphics painting. Installed after looking at the source and related documentation)

用C++模拟LBM的couette流源代码，使用周期边界和曲线边界条件。(LBM simulation using C++ source code of couette stream, using periodic boundary conditions and boundary curves.)

测绘方面的道路中桩计算程序。缓和曲线、圆曲线。(Surveying and mapping aspects of the road in the pile calculation program. Curve, the circular curve.)

说明：  一个Visual Graph开发程序，具有类似MS viso的功能！带有C++,Delphi,VB,C#等的代码示例！(a Visual Graph development programs that have similar functions VISO MS! With C, Delphi, VB, C# code examples!)

数控代码自动生成,Bizer曲线的数控加工代码的自动生成，VC++实现功能(NC create)

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.)

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)

采用层次包围盒、八叉树加速的光线跟踪算法(ray tracing using level boundary box and eight branch tree algorithm)
