Week10 柯竹盈

一、貼圖

解壓縮opengl

把freeglut放入opengl資料夾裡面

到FB電腦圖學社團下載my earth，找earth map的圖放入myearth資料夾

打開myEarth.exe檔，就完成

作業二--旋轉地球

打開my earth的project file (.cbp)檔

要把google.jpg放入，freeglut\bin裡面

Week 15 林庭亘

課堂作業1:

利用Excel 練習內差公式

內差公式

課堂作業2:

內差公式應用

應用公式

課堂作業3:

新增輔助程式

利用S按鍵儲存座標

利用R按鍵讓機器人動起來

}

程式要改:
1.motion()不要狂寫檔
2.keyboard()裡if(key=='s')要寫檔
SAVE一次到定位
3.keyboard()的'r'讀一行改裝't'先讀一行對應timer
4.加上timer glutTimerFunc

課堂作業一
利用 Excel 計算內插 Interpolation

首先公式如下 =27*a5+10*(1-a5)

接著利用鎖定公式 =$C$12*A6+$C$2*(1-A6)
