 1-1

  到jsyeh.org/3dcg10下載範例

   windows.zip 下載\windows\Texture.exe

    data.zip    下載\windows\data\圖檔

    1-2下載OpenCv點選中間之後存在c槽。

      

看到有出現OpenCv表示下載完成也成功了

2-1

codeblock中開啟empty new file 然後存成week09_opencv,cpp然後打入程式碼

#include <opencv/highgui.h>

int main()

{

    IplImage * img =

    cvLoadImage("week09.png");//讀圖

    cvShowImage("week09", img);//秀圖

    cvWaitKey(0);//等任意建繼續

}

Setting-Compiler-Search directories-Compiler-Add C:\OpenCV2.1\include

Search directories-Linker-Add C:\OpenCV2.1\lib

Setting-Compiler Setting-Linker setting 輸入:cv210 

cxcore210  , highgui210 

最後能秀出圖片

#include <GL/glut.h>

#include <opencv/highgui.h>

void myTexture()

{

    IplImage * img = cvLoadImage("earth.jpg");//去找地圖

    cvShowImage("img", img);//img視窗的圖

    cvWaitKey(0);任意鍵繼續

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week09 texture");

    glutDisplayFunc(display);

    myTexture();

    glutMainLoop();

}
