自动绘制保护煤柱,CAD 二次开发的，输入参数后，自己就绘制出来了(Automatic drawing protection pillar, CAD secondary development)

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)

用于C/C++/Visual C 二二维等值线的绘制，程序源码 (Drawn for two two-dimensional contour of the C/C++/Visual C program source)

说明：  MFC坐标系的绘制，动态显示曲线，感兴趣的可以参考下~~(MFC frame rendering, dynamic display curves of interest can refer to the following ~ ~)

简单计算机图形学算法，通过直线中点Bresenham算法,绘制直线。( Simple computer graphics algorithms, Bresenham line passing through the midpoint algorithm, draw a straight line.)

体积小巧曲线控件没，实现一般曲线的各种画法，虽然很简单但很好用。(compact design Curve Controls did not achieve normal curve of the painting, although very simple but very good use.)

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)

基于Bresenham算法的四步画直线算法,加快画直线速度(draw line based Bresenham update alogrith)

利用C++实现的对杨辉三角形的模拟，可以在界面上打出杨辉三角形的内容。 (Achieved by C++ analog Triangle, Triangle content can be played on the interface.)

CAD下VBA二次开发，用来展高程点，txt文件，已经把离散点网格化了(CAD lower VBA secondary development, to show elevation point, txt file, has the discrete points of the grid)
