設定opencv

秀一張2D照片程式碼:

#include <opencv/highgui.h>

int main()

{

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

    cvShowImage("2D",img);

    cvWaitKey(0);

}

設定freeglut

#include<Gl/glut.h>

#include <opencv/highgui.h>

float angle=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT);

    glPushMatrix();

        glRotatef(angle, 0,1,0);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glFlush();

    angle+=0.1;

}

int main(int argc, char**argv)

{

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

    cvShowImage("2D",img);

    //cvWaitKey(0);

    glutInit(&argc,argv);

    glutCreateWindow("3D");

    glutDisplayFunc(display);

    glutIdleFunc(display);

    glutMainLoop();

}

2D與3D

#include <GL/glut.h>

#include <opencv/highgui.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);

    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)
