NURBS曲线的导数算法

本软件(ZHG制图工具)由ZHG用C/C++开发，可用来进行简单画图、查看由本软件制作的图形文件以及使用配套函数show_bmp在C语言程序中直接使用已画好的图形。具体操作如下： 1.主界面上方为菜单栏，左边为工具栏。要使用请单击“新建”或“打开”按钮，退出可单击右上角椭圆。 2.进入后，可单击工具栏选择画笔、规则图形及颜色。左击图形库，画实线图，右击可画虚线图。在编辑区中，用左键拖动鼠标为画笔画图，右键拖动可画规则图形。（建议下载到D盘，并先阅读说明文件。） -the software (ZHG mapping tool) from ZHG with C/C development, which can be used for simple drawing, View from the software produced by the graphics files and the use of complementary functions in C language show_bmp procedures used directly Painting has good graphics. Specific operations, as follows : 1. The main interface to the top menu bar, as a tool for the left column. To use click "new" or "open" button, can withdraw from the upper right elliptical. 2. After entering, click column selection brush tool, rules and color graphics. Left attack graphics library, painting solid lines map, right click on the dotted line can be painted map. Editing area, and use the mouse to point and drag brush painting, the right-scrolling graphics
