主題 : 攝影機、運鏡
主題 : 投影、矩陣
複習 : 位置移動、轉動
複習 : 背景貼圖
(1) 到 這裡 下載 [data]、[win32]、glut32.dll
(2) 把data、glut32.dll丟進windows裡面
(3) 開啟 projection.exe
(4) 調整數值可以改變運鏡
(5) 下載 [source}
(6) 到 這裡 下載壓縮檔
(7) 複製貼上並重新命名為libglut32
(8) 將data丟進freeglut資料夾的bin
(9) 開啟codeblocks
(10) 選擇 GLUT project
(11) 把source的三個檔案移動到codeblocks資料夾
(12) 並把glm.c改名為glm.cpp
(13) 把codeblocks 內的程式碼刪掉並在旁邊新增( sdd files ) 並點選glm.cpp
(14) 並點選projection 開啟他的程式碼並複製貼上到codeblocks裡面
(15) 即可得到
(16) 複製貼上老師給的程式碼即可以得到一個黑底白人
( 此為程式碼 )
