基于小波变换的三维模型提取技术的毕业论文,包括代码和答辩ppt.1．实现了三维模型的表示和规范化预处理过程，在此基础上，开发了进行检索实验的可视化特征提取实验平台。
2．结合球面调和变换获取旋转不变量具有降低特征向量维数的特性，实现了基于光线投射的特征提取方法，通过检索评价实验确定了参数的最佳取值。
3．分析了基本的光线投射方法和改进的光线投射方法的缺陷，提出了一种基于三维小波变换的特征描述方法。对光线投射算法进行了扩展，将切比雪夫采样点序列进行离散小波变换，然后利用球面调和变换获得旋转不变的特征向量。
4．将小波变换引入到体素表示的三维模型中，分别实现了表面体素小波变换和实体体素小波变换的特征提取，通过实验比较分析实体体素小波变换优于表面体素小波变换。

一款开源的完整矢量绘图控件源码,支持直线、弧线、矩形、圆角矩形、椭圆、多边形、星形、文本和图片等的绘制，支持旋转、缩放、选择、排列等操作，总的说来功能还是不错的！其实如果稍微懂点计算机图形学的知识要做出比这个还要完善的矢量绘图软件应该是没有问题的。
VB6本身对于绘图的支持是非常弱的，因此一般直接通过其内置方法实现的绘图效率都成很大的问题。解决方法之一是采用Windows API来进行底层GDI的绘制，更好的方法是采用GDI+来绘图，这样效果会更好。
-A complete open source vector graphics controls in support of a straight line, arc, rectangle, rounded rectangle, ellipse, polygon, star, text and pictures, such as rendering, support for rotation, zooming, selection, arrangement and other operations, the total to function or that good! In fact, if a little point of computer graphics to understand the knowledge to make than that perfect vector drawing software should not be any problem. VB6 their support for the graphics are very weak, so the general method of directly through its built-in graphics to achieve efficiency into a big problem. One solution is the use of Windows API for the underlying GDI rendering, and better way is to adopt GDI+ To graphics, so the effect will be even better.
