一.上週作業
(1)開起自己的檔案
(2)並用NotePad++開啟，把include和lib目錄設對，working目錄設"."(句點)
二.讓機器人動
三.Timer計時器
#include <stdio.h>
void timer(int t)
{
printf("我現在起床了，t是%d...",t);
glutTimerFunc(100,timer,t+1);
printf("我撥了一個新的timer...");
angle++;
glutPostRedisplay();
printf("記得重畫畫面喔!我睡了，bye\n");
}
glutTimerFunc(2000,timer,0); ///睡前，先設定一個鬧鐘，2秒後會叫
四.鍵盤滑鼠控制

#include <stdlib.h>
#include <GL/glut.h>
#include "glm.h"
