一个新创的算法（复杂）-created a new algorithm (complex)

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

Bezier曲线由三个点确定，此程序用C实现了三次Bezier曲线图形的绘制-Bezier curve determined by three points, this procedure three times with the C implementation Bezier curve drawing graphics

图像的旋转算法，很实用-image rotation algorithm, a very practical

演示了OpenSceneGraph（OSG）中如何根据法线图片快速生成简单地形，以及任意物体阴影在此地形上的投射。 VS 2008+OSG 2.6测试通过-Demonstrate the OpenSceneGraph (OSG) in accordance with normal picture of how quickly generate simple terrain, as well as the shadow of arbitrary objects in this topographical projection. VS 2008+ OSG 2.6 test

VB绘制正弦线，用VB实现在图片框中绘制坐标轴，并在坐标系内动态生成正弦线。注释：首先清除picture1内的图形，设置绘线宽度，绘坐标系的X轴及箭头线，绘坐标系的Y轴及箭头线，指定位置显示原点O，重设绘线宽度，用For循环绘点，使其按正弦规律变化。步长值很小，使其形成动画效果，指定位置显示描述文字
