week14 電腦凸學

 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.到codeblock開新的專案 file > project,(檔名為week13-0)

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

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

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

11.3.加入linker 設定的 3個檔名cv210 cxcore210 highgui210

12.下載git啟動器 

13.將上週的week13-2從github下載下來

14.將剛剛的專案,先關起來Close Project (不然會被鎖),將目錄從13-2複製到14-1,新檔案名改為14-1,最後再把專案的Title改成 week14-1,用notepad++打開cbp檔把裡面week13-2改為week14-1

15.開啟一個Excel 

16.加上一些數值

17.在角度alpha上加一個alpha公式(新的*alpha+舊的*(1-alpha))

18.加上timer的函式

19.設定時間軸還有撥放按鍵

20.複製14-1改為14-2_angleX_angleY_10

21.將按鍵新增到10個，將angle[20]改為float angleX [10]={},angleY[10]={}，for迴圈裡改為10

22.將所有有angle的部分改為angleX或angleY

23.上傳github
