Week05_打光

像上禮拜一樣先去
http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/
下載    win32    data    glut.dll
跟上禮拜動作一樣然後打開Light Material.exe

把上次的茶壺的程式碼貼上去，然後再加上一堆程式碼，就能幫茶壺打光。
老樣子開codeblocks建立一個project，選glut，再去https://www.transmissionzero.co.uk/software/freeglut-devel/
下載Download freeglut 3.0.0 for MinGW
//黃色的是打光
//綠色的加上去會旋轉

#include <GL/glut.h>

    glMaterialfv(GL_FRONT, GL_SHININESS, high_shininess);

    glutMainLoop();
