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)

可以画图的功能强大cad软件一定不要错过你值得拥有制图高级工具(You can paint the powerful CAD software must not miss you worthy of drawing advanced tools )

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)

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)

代码是关于Peano-Hilbert曲线算法，属于图形学范畴(Code is on the Peano-Hilbert curve algorithm, belongs to the category Graphics)

实现从SDK到MFC的封装 增加了绘制线条 矩形 椭圆等功能 而且可以变换颜色(none sdk to mfc)

二维绘图，包括直线，矩形，圆，多边形等绘制(Two-dimensional graphics, including lines, rectangles, circles, polygons drawn)

一个用来显示Autocad内部数据结构的极佳工具. Autocad2006二次开发人员必备!(used to indicate an internal data structure Autocad an excellent tool. Autocad2006 Secondary Development staff required!)
