1.下載OpenCV2.1

2.codeblock設定

3.將程式碼完成便會出現圖片檔

#include <opencv/highgui.h>

int main()

{

   IplImage * img = cvLoadImage("image.jpg");

   cvShowImage("2D 02160961",img);

   cvWaitKey(0);

}

4.加入freeglut32

5.將圖片環繞在茶壺上

#include <opencv/highgui.h>

#include <GL/glut.h>

#include <opencv/cv.h>

float angle=0;

void display()

{

    glEnable(GL_DEPTH_TEST);

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glRotatef(angle,0,1,0);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glFlush();

    angle+=0.1;

}

void init()

{

    IplImage * img = cvLoadImage("image.jpg");

    cvCvtColor(img,img,CV_BGR2RGB);

    glEnable(GL_TEXTURE_2D);

    GLuint id;

    glGenTextures(1,& id );

    glBindTexture(GL_TEXTURE_2D,id);

    glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_WRAP_S,GL_REPEAT);

    glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_WRAP_T,GL_REPEAT);

    glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_NEAREST);

    glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_NEAREST);

    glTexImage2D(GL_TEXTURE_2D, 0 ,GL_RGB,img->width,img->height,0,GL_RGB,GL_UNSIGNED_BYTE,img->imageData);

}

int main(int argc,char**argv)

{

   //IplImage * img = cvLoadImage("image.jpg");

   //cvShowImage("2D 02160961",img);

   //cvWaitKey(0);

   glutInit(&argc,argv);

   glutCreateWindow("3D");

   glutDisplayFunc(display);

   glutIdleFunc(display);

   init();

   glutMainLoop();

}

#include <opencv/highgui.h>

float angle=0;

GLUquadric * quad;

void display()

{

    glEnable(GL_DEPTH_TEST);

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glRotatef(-90,1,0,0);

        glRotatef(angle,0,0,1);

        gluQuadricTexture(quad,1);

        gluSphere(quad,0.5,30,30);

    glPopMatrix();

    glFlush();

    angle+=0.1;

}

void init()

   //cvWaitKey(0);

   glutInit(&argc,argv);

   glutDisplayFunc(display);

   glutIdleFunc(display);

   init();

   glutMainLoop();
