今天下載OpenCV-2.1.0-win32-vs2008.exe

步驟如下：

下載vVERSION2.1.0

ˋ

這次的步驟前面真的有點小複雜，但很快一步一步做就做好了

先去網路上抓了一個可愛的小丸子剪壞頭的可愛圖

1.打程式碼讓視窗跑出一張圖

2.接下來做旋轉的

現在只有茶壺旋轉圖另外出來

接下來想辦法讓小丸子圖放到茶壺上然後又可以旋轉

程式碼;

#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("abc.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)

{

    glutInit(&argc, argv);

    glutCreateWindow("3D小丸子");

    glutDisplayFunc(display);

    glutIdleFunc(display);

    init();

    glutMainLoop();

}

之後要做一顆有小丸子圖的球

球的形狀的小丸子

程式碼：

#include <GL/glut.h>

#include <opencv/highgui.h>

#include <opencv/cv.h>

float angle=0;

GLUquadric * quad;

void display()

{

    glEnable(GL_DEPTH_TEST);

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glRotatef(-200, 1, 0, 0);

        glRotatef(angle, 0, 1,0);

        gluQuadricTexture(quad, 1);

        gluSphere(quad, 0.5, 30, 30);

    glPopMatrix();

    glFlush();

    angle+=0.1;

}

void init()

{

    quad = gluNewQuadric();

    IplImage * img = cvLoadImage("abc.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)

{

    glutInit(&argc, argv);

    glutCreateWindow("3D小丸子");

    glutDisplayFunc(display);

    glutIdleFunc(display);

    init();

    glutMainLoop();

}
