open cascade 二维图形生成例子程序(open cascade two-dimensional graph of sample program)

MFC 画出简单的坐标 并通过按钮产生随机点坐标（横坐标逐渐增大纵坐标随机）存入文件中 另一按钮实现读出数据并将点连成折线(MFC drawing simple coordinate and through the button generates random point coordinates (abscissa increases ordinate random) into a file and another button to achieve read data points connected into line)

用于拟合椭圆的函数，支持对于多个离散数据点的椭圆曲线方程计算(new function)

能够对通达信.lc5文件进行修改，主要是修改分钟数，这样可以在两年多的数据中进行画线处理(Mastery letter. Lc5 file to be modified, modify the number of minutes, so you can draw lines in more than two years of data)

说明：  计算机图形学实验，完成立方体的三视图和等轴侧投影(Computer graphics experiments, the completion of three cube view and isometric projection)

极其简单的MFC画图小例子，但是可以学到很多的基本知识，不错的例子，微软出品！！！！(Extremely simple MFC drawing small example, but you can learn a lot of basic knowledge, a good example, Microsoft Publisher! ! ! !)

本文以电场的三大定理、连续超张弛迭代算法、拉格朗日插值算法等原理知识作为理论基础，以 C 语言为编程工具，将由根据以上物理和数学原理所推导出来的模型转化为可以计算像管内电势的 CAD 程序软件。所编写的程序可以在给定像管参数和电极电位的情况下，计算圆柱形像管内任意一点的电位大小，并绘制出像管内的等势线；拉格朗日插值得到对称轴上任一点的电位值。 (In this paper, we base on the three theorems of the electric field, continuous ultra-relaxation iterative algorithm, and Lagrange interpolation algorithm. We use the C language as a programming tools, and transform the model derived above into a CAD software to calculate the electric potential in the image tube. In case the image tube parameters and electrode potential are known, the program written can get the potential of every point in the image tube, and plot equipotential lines inside the image tube. It can also get the potential of every point on the axis of symmetry by Lagrange interpolation. )
