1.下載OpenCV

2.1.OpenCV設定: Setting Compiler / Search Directories / Compiler / include: C:\OpenCV2.1\include

2.2.OpenCV設定: Setting Complier / Search Directories / Linker lib 目錄:

C:\OpenCV2.1\lib

2.3.OpenCV設定: Setting Complier / Linker設定 cv210 , cxcore210 ,highgui210

2.4 earth.jpg圖檔放哪裡，codeblocks工作目錄 working dir ( freeglut/bin )

3.利用 glBegin(GLUT_POLYGON) , glEnd() ,中間夾4次(4個角) glTexcoord2f()

4. week10-textrue-background貼圖背景

程式碼:

5.week10-texture-earth上週貼圖+貼到圓球=地球

👉 GLUquadric * sphere=NULL;///指標指到二次曲面

      main中: 

      gluQuadricTexture(sphere,1);///設好貼圖

      gluSphere(sphere,1,30,30);///畫圓球

      display中:    

      sphere=gluNewQuadric();///準備好二次曲面

結果:

程式碼:

6.week10-texture-earth-rotate讓地球旋轉

👉float angle=0;///旋轉角度

      display中:

      glRotatef(angle,0,1,0);///把它轉正

      angle+=0.05;///每執行1次，加1度

      main中:

      glEnable(GL_DEPTH_TEST);///開3D深度

      glutIdleFunc(display);///有空idle呼叫display

結果:

程式碼:
