教你如何使用画刷，MFC里面的画刷，文件里面是相关的代码。(tell you how to use the brush of MFC,there s the relative code inside the file.)

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)

用于求解各阶贝塞尔函数和汉克尔函数零点，希望对大家有帮助。(besselj and hankel functions)

说明：  根据图框块自动识别图纸并预览打印。函数参数分别为：打印机名称，打印样式，打印纸张，打印份数，自动纸张，自动旋转，自动关闭，自动识别图框(Autoprint according to the drawing blocks.)

PSCAD仿真,可以设置各种故障,故障类型可以自由设置,并且得到故障仿真图形,本程序中附有单相故障(PSCAD simulation, you can set a variety of failures, fault types can be set free, and get fault simulation graphics, the program with a single-phase failur)

cad文本输入，适合宗地号输入。地籍测绘作业宗地号预编使用。(cad text input, suitable parcel number input.Cadastral mapping operations parcel number pre-programmed to use.)

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.)

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))

用MFC实现画图板，包括绘线，几何图形，上色等等，简单易懂。(To realize drawing board with MFC)
