是我是我詐騙 Week08

  

🥡 貼圖 🍱

1.設定

🍙linker settings🍙

cv210

cxcore210

highgui210

🍙search directories🍙

compiler

c:\OpenCV2.1\include

linker

c:\OpenCV2.1\lib

2.寫程式，讓他圖片能跑出來

程式碼如下:

#include <opencv/highgui.h>

int main()

{

    IplImage*img=cvLoadImage("01.jpg");

    cvShowImage("week08",img);

    cvWaitKey(0);

}

3.用成專案，為了確認圖片可不可以用

🍩圖片要儲存在freeglut\bin🍩

程式碼如下:

#include <opencv/highgui.h>

int main()

{

    IplImage*img=cvLoadImage("01.jpg");

    cvShowImage("week08",img);

    cvWaitKey(0);

}

4.讓圖片貼在茶壺上

程式碼如下:

#include <opencv/highgui.h> ///使用 OpenCV 2.1 比較簡單, 只要用  High GUI 即可

#include <opencv/cv.h>

#include <GL/glut.h>

void init()

{

    IplImage * img = cvLoadImage("01.jpg");   ///OpenCV讀圖

    cvCvtColor(img,img, CV_BGR2RGB);   ///OpenCV轉色彩 (需要cv.h)

    glEnable(GL_TEXTURE_2D); ///開啟貼圖功能

    GLuint id;    ///準備一個 unsigned int 整數, 叫 貼圖ID

    glGenTextures(1, &id);    /// 產生Generate 貼圖ID

    glBindTexture(GL_TEXTURE_2D, id); ///綁定bind 貼圖ID

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);    /// 貼圖參數, 超過包裝的範圖T, 就重覆貼圖

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);    /// 貼圖參數, 超過包裝的範圖S, 就重覆貼圖

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);   /// 貼圖參數, 放大時的內插, 用最近點

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);   /// 貼圖參數, 縮小時的內插, 用最近點

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

}       ///貼圖影像的資料都設定好

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glBegin(GL_POLYGON);

        glTexCoord2f(0,1); glVertex3f(-1,-1,0);

        glTexCoord2f(1,1); glVertex3f(+1,-1,0);

        glTexCoord2f(1,0); glVertex3f(+1,+1,0);

        glTexCoord2f(0,0); glVertex3f(-1,+1,0);

    glEnd();

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

int main(int argc,char** argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("08160554");

    init();

    glutDisplayFunc(display);

    glutMainLoop();

}

🏈完成圖🏈

4.圓形旋轉

程式碼如下:

#include <opencv/highgui.h> 

#include <opencv/cv.h>

#include <GL/glut.h>

GLUquadric * quad;///TODO: Quad

void init()

{

    IplImage * img = cvLoadImage("02.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);

    quad = gluNewQuadric();///TODO: Quad

} 

float angle=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();///自動轉

        glRotatef(90, 1,0,0);

        glRotatef(angle, 0,0,1);///自動轉

        gluQuadricTexture(quad, 1);///TODO:

        gluSphere(quad,0.5,30, 30);///glutSolidTeapot(0.3);

    glPopMatrix();///自動轉

    ///glutSolidTeapot(0.3);

    glutSwapBuffers();

    angle++;}

int main(int argc, char** argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week07 texture");

    glutDisplayFunc(display);

    glutIdleFunc(display);

    glEnable(GL_DEPTH_TEST);  ///有3D的深度測試(前面會蓋掉後面)

    init();///上面把OpenGL都設好後, 才設定 OpenCV 的貼圖到 OpenGL上面

    glutMainLoop();

}
