電腦圖學 2019-05-30 Week15
(1).主題 : 攝影機 , 運鏡
(2).主題 : 投影 , 矩陣
(3).複習 : 移動位置 v.s. 轉動
(4).複習 : 背景貼圖
(5).期末作品
(一)開啟Projection.exe
先到http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/下載3個並且解壓縮
把data和glut32.dll丟到windows裡面
(二) 開Code::Blocks
1.先到google搜尋freeglue windows，找Transmission Zero的網頁，Download以下畫面文件
2.解壓縮的畫面
複製libfreeglut.a改成libglut32.a
3.打開Code::Blocks
4.右上File找New在按Project出現以下畫面，找GLUT後按GO
4.按完GO後出現以下畫面，輸入檔案名稱後按Next
