Week14 劉念慈的上課筆記

20170523

電腦圖學

課堂作業:
(1)上周作業
(2)讓機器人動
(3)Timer計時器
(4)鍵盤滑鼠控制
(5)機器人2.0
-------------------------------------------------------------------------------------------------------------
TODO1:(用邱繼儀範例)
(1)cdp專案檔
    用Nope++開include目錄
    lib目錄設對
    working目錄設" 。"


TODO2:
計時器
week14_01timer.cpp

#include <stdio.h>
void timer(int t)
{

    glutTimerFunc(100,timer,t+1);
    printf("我撥了一個新的timer....");
    angle+=3;
    glutPostRedisplay();
    printf("記得重畫畫面哦! 我睡了,byb\n");


}
