Description: 1． 做一个集成的图形界面的程序，可调用每一次作业子程序。
2． 调用画点的函数，用DDA、中点算法画直线和中点算法及正负法画圆和抛物线。
3． 交互式的二维直线求交：如果存在交点，用实心圆显示交点，并用文字显示其坐标。
4． 用动画实现二维图形变换的各种算法，实现对指定形体的平移、旋转和缩放。（包括自行车行走和绕固定点旋转的自旋转物体动画。）
5． 线段裁剪和多边形裁剪算法的动画演示实现。（两种线段裁剪算法和H-S多边形逐边裁剪算法）多边形裁剪算法的动画演示要求先画出一个封闭的多边形，再画矩形的裁剪窗口，然后选择裁剪按钮（或命令），按下“上边裁剪”按钮（或执行“上边裁剪”命令），多边形相对裁剪窗口的上边进行裁剪，显示上边裁剪后的多边形，依此进行其它各边裁剪。
6． 两种扫描多边形扫描转换算法实现（扫描线算法为必做，基于求余运算的边缘填充和边标志算法任选一种）；
7． 4连通区域的递归种子填充算法，和扫描线种子填充算法，要求种子点(x,y)可交互输入）。
8． 简单三维图形系统：凸多面体的建模、透视投影，隐藏面的消除及基本图形变换（平移、旋转、缩放）。

Description: This the third tutorial in the Foundation section. This tutorial covers the basics of drawing some simple 2D polygons such as triangle, pentagon, rectangle etc. We will make use of the code that we had generated in the previous section. We ll cover some important topics such as Clipping Area, Viewports, Vertex and the Primitives in OpenGL such as the point, line, triangle, polygon, quads etc. We ll write a program that is menu driven and draws points, triangles, lines, quads etc.

Description: The package must also have a user-friendly interface that may be menu-oriented, iconic or a combination of both. It provides most the features that a 2D graphic editor should have. It is developed in C. it has been implemented on DOS platform. The 2-D graphics package designed here provides an interface for the users for handling the display and manipulation of basic picture objects like point, line, rectangle, ellipse, polygon, spiral, etc. It can also perform operations on selected objects like clipping, translation, rotation, area filling etc. It is capable of loading and saving the picture files. The interface is user –friendly with icons for all the functions.

Description: 一个三维医学图像实时可视化系统,4DView能有效地解决三维医学图像可视化及其交互操作实时性不强的问题,在临床诊断、治疗和医学研究等领域中具有极大的应用前景.-4D data exploration，This is an extension of the 3 linked cross-sections of a volumic data to the time domain. It is invoked command-line through a syntax as simple as fn_4Dview(data) or more elaborated as fn_4Dview(Y, clip ,[0 40], 2d , in ,2, time , fifth ,1) .
Interesting features are:
- mouse-selection of regions of interest (ROI) and plot their time courses
- mouse-selection of frames to bin
- display of velocity images (quiver) and mesh surfaces available as well
- handle transformation between different referentials
- specify the clipping
