Meshlab和VCGlib都是意大利国立研究院的作品，meshlab提供了大量的模型分析与处理的算法，而VCGlib建立了基础的数据结构及其遍历访问的算法，也提供了模型的基本处理算法。VCGlib是标准C++库写的，其提供了IO与封装OpenGL来显示。Meshlab的界面是用QT来写的，因此需要QT SDK的支持。

对于一些图像来说，常用的边缘检测算法有时候无法设立合适的阈值将它们的梯度较小的模糊边缘检测出来。为了解决这个问题，有两种解决方法：将图像方差标准化，拉大模糊边缘的梯度值，或通过设置sigmoid函数，将像素所在区域的信息传递到梯度值中去，对其进行调整，就能找到合适阈值，有效地将模糊边缘提取出来。本程序把这两种算法实现并与与传统算法进行了比较。-For some images, the commonly used edge detection algorithm sometimes can not be an appropriate threshold for the gradient of their smaller fuzzy edge detected. To solve this problem, there are two solutions: the image variance standardization, widening the fuzzy edge of the gradient value, or by setting the sigmoid function pixel region to disseminate the message to the gradient values to adjust, on the can find a suitable threshold, effectively extracted fuzzy edge. This procedure of these two algorithms with the traditional algorithm.

这是一个简单的绘图程序，编制该程序的过程包括建立应用程序的基本框 架、处理视图、处理文档、串行化处理、滚动处理、窗口分割、创建对话模板 资源、创建对话类、定义成员变量、定义消息处理函数、创建对话类对象并显 示对话框以及添加工具栏按钮。 该程序的功能就是在单文档窗口中绘制各种不同线宽（有六种线宽）、不 同风格（有三种风格：实线、划线和点线）和不同颜色的线段。并且具备保存、 恢复、撤消、滚动、窗口分割等功能。 该程序所用到的都是Visual C++最基本、最核心的内容。-This is a simple drawing program, the preparation of the procedures for the establishment of the process, including the application of the basic framework for handling View, documents, serial processing, and rolling, window segmentation, create dialogue template resources, the creation of such a dialogue, the definition member variables, the definition Message Handling Functions to create dialogue and object type dialog box appears and add toolbar button. The procedure is the function of a single document window mapping different width (a six linewidth), the different styles (three styles : solid line, and crossed point line) and different colors segment. And with the preservation, restoration, lifting, rolling, the window segmentation capabilities. The
