图形学试验内容及报告模板

1、实验内容一： 1实现图形的生成算法，实现直线、圆、椭圆的生成算法，对各种算法进行效率及效果的分析和比较，学有余力的同学可在对现有算法理解的基础上，能自行设计二维图形的生成算法并编程实现。 2实现填充算法，能搞实现矩形、多边形、圆、椭圆的填充。3实现裁剪算法，理解并实现直线和多边性裁剪，对各种直线裁剪算法进行效率及效果的分析和比较。4实现图形的坐标变换，实现二维图形的基本变换，包括平移、旋转、比例、对称变换。5实现简单的三次Bezier曲线。实验指导：第一步：进一步了解计算机图形学课程的知识结构体系，绘制整个课程的知识结构逻辑示意图，类似于：（图一）第二步：根据所绘制的知识结构图，设计DOS菜单

2、，要利用多级菜单实现各种功能。比如，主界面是大项，诸如二维线画图元、二维填充图元、二维裁剪等，子菜单使这些大项中的一些功能或者小项。#include graphics.hVoid DDACircle()Void m_zhongzitianchong().main()int r=100; int a=0; int b=1; int d=1; int s=1; int x1,y1,x2,y2,x3,y3,x,y,h; int color=1,color2=1; int gdriver,gmode; gdriver=DETECT; gmode=0; initgraph( &gdriver,&
