5、整体的框架，需要做哪些事物，以及每个事物的大体位置，接着计算各个点的坐标，之后分工进行，每个人做一到两个事物，最后将所有事物整合在一起。 还遇到的一个问题是，保证所有物体能够合理的展现出来，不出现掩盖或不能显示效果的现象，这首先是对物体的创建和坐标的把握，然后是对基本变换功能的掌握，对于这方面的设计，不仅需要严谨计算还要学习功能的设计。Design and Implementations： 一开始大体的想法是设计一个带有烟囱的尖顶房子，后来在做房顶的时候遇到了困难，房顶的两侧无法显示，后来找到的改进方法是将房顶做成一个长方体，并将长方体上的两个点合并，并缩短X轴上的距离，加上深度测试，最终出现
6、了想要的效果；之后用类似的方法做出了树和小狗住的房子；太阳一开始想用实验三的方法通过圆去做，后来效果不理想，我们组在网上找到了glutSolidSphere();画球的方法。由此也学会了glutSolidCube();画立方体的方法，利用这种方法做出了栅栏，然后两者综合做出了机器人Shortcomings： 设计完实验作业，我们存在着很多的不足，首先，构图坐标有些繁杂冗长，导致代码的篇幅有些长。第二，因为功底是在太差，没有做出贴图和光源，导致整体不是很漂亮。第三，实验思路有些混乱，经常是想起来什么就做什么，导致效率变低。 Conclusions： 总体来说，能够把项目做到这样的效果，我们还是很
7、满意的，但是还是对没有将四面的背景分别设定表达感到遗憾。 如果要重新做一遍，我会选择学习并使用纹理的表现，这个功能的优点是能够使事物表现更为逼真。 这门课程让我对CG这门学科有了最基本的认识和学习，希望以后有机会可以多加接触。Appendix： #include#include#include#include using std:cout;#define _USE_MATH_DEFINES #include double rotate_y = -15; /定义键盘控制旋转X轴，默认-5度double rotate_x = -15; /定义键盘控制旋转Y轴，默认0度GLfloat w = 800
