在Vc环境下 仿CAD编程（源代码）-Vc environment in imitation of CAD programming (source code)

功能:连接多义线,将选定标注改为当前标注形式,给标注文本加括号,恢复所有图层先前状态-Features: Connect polyline will be replaced by the current marking of selected forms of tagging, to mark the text in brackets added to restore the previous state of all layers

这时一个形状各不相同的窗体程序，例子给出了多种形状的窗体。-Shape when a different form procedures, examples are given a variety of shapes form.

这个程序作为输入需要三字经，然后绘制一个文件。使用函数 iradon，程序将会重建层析图像使用从输入的三字经。四个不同的筛选器被用于重建 ︰ Ram Lak、 Shepp_Logan、 汉和汉明。绘制的图形显示所有四个重建图像和像素值。

通过重复使用一小块顶点缓冲来减少对内存的需求，将CPU从逐帧的顶点缓冲更新中释放出来-Through the repeated use of a small vertex buffer to reduce the demand for memory will be the culmination of CPU from the frame buffer update released

本地脚本生成随机数字,用图像显示!-err

sample : unicode16 transfer to UTF8

一个关于图片合成的程序，将动态生成的文本和图片对象与背景图片合成。-a picture on the synthesis procedure will be dynamically generated text and pictures objects and background images synthesis.

透视投影的生成算法-perspective projection algorithm for the generation

生成一系列点的二次回归方程。以读文件方式读取数据，并可自设比例尺显示在屏幕上，然后进行回归，并可进行显著性检验。-generate a series of points of quadratic regression equation. Reading papers to read data, as well as self-imposed scale display on the screen and then return to carry out significant test.
