图形学实验三：Texture Mapping
唉，还是上学期做的实验，不过由于快到期末要复习考试，没有来得及整理。。。这学期刚开学没多久，时间比较多，就赶紧整理整理下~~
纹理映射学习参考
推荐一个老师给我们的网站，很好，虽然是英文，但讲得很详细！
NeHe’s OpenGL Tutorials
里面第八个就是讲关于Texture Mapping的
Texture Mapping
讲得很好，我也懒得整理了，而且英文也挺容易看懂的，看看也正好可以练练英语，对吧，嘿嘿。“
实验内容
本次实验内容，是老师让我们在第二个实验的基础上，增加纹理映射，以及移动。也就是在我第二个实验中的“火柴人”的基础上，给它穿点衣服，顺便让它手、脚能动起来。手、脚动起来，这就要涉及分层设计，这个在我第二个实验的文章中一开始就已经提到了：
图形学实验二：画个火柴人
我画的火柴人，手和脚能自动动起来，就像在走路。顺便还加了个键盘控制：
- ‘q’:控制Larm1；’w’:控制Larm2
- ‘a’:控制Rarm1；’s’:控制Rarm2
- ‘e’:控制Left leg1；’r’:控制Left leg2
- ‘d’:控制Right leg1；’f’:控制Right leg2
- ‘z’:控制整个火柴人绕y轴旋转
- ‘x’:控制整个火柴人绕x轴旋转
- ‘c’:控制整个火柴人向右平移
- ‘v’:控制整个火柴人向左平移
具体的就不说了，贴上代码和截图吧~~
