李凹凹

 1 .從上課軟體下載freeglut




 2.將壓縮檔解壓到桌面

3.點開freeglut後復製其連結


4.點開lib後將freeglut.a復製


5.改名為libglut32.a (124KB)

6.把上週week10-1的程式拿過來

新增專案 week11-1 

7.opencv安裝


8.選項選2或3
9.不要更換目標資料夾
10.重開codeblocks

11.設定Settings-compiler要加入三個設定


12.search 目錄 compiler 的include 目錄 加 C:\OpenCV2.1\include



13.search 目錄 linker 的lib 目錄 加 C:\OpenCV2.1\lib

14加入linker 設定的 3個檔名cv210 cxcore210 highgui210
15.修改上週程式碼
16.新增專案week13-1_glm_gundam_keyboard_angleID_mouse_motion_angle
17.修改程式碼
