第八周上課內容

1.用opencv秀圖:

 

程式碼:

#include <opencv/highgui.h>

int main()
{
IplImage * image1=cvLoadImage("images.jpg");
cvNamedWindow("00161081");
cvShowImage("00161081",image1);
cvWaitKey(0);
return 0;
}


2.旋轉鬱金香:

3.茶壺+地圖轉動:
程式碼:
#include <GL/glut.h>
#include <opencv/highgui.h>
#include <opencv/cv.h>
GLuint id;
float rot=0;
void display()
{
 glEnable(GL_DEPTH_TEST);
 glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
 glEnable(GL_TEXTURE_2D);
 glBindTexture(GL_TEXTURE_2D,id);
    glPushMatrix();
        glRotated(rot,1,0,0);
      glutSolidTeapot(0.3);
       
        glBegin(GL_POLYGON);
   glTexCoord2f(0,0);glVertex3f(-1,-1,0);
   glTexCoord2f(1,0);glVertex3f(1,-1,0);
   glTexCoord2f(1,1);glVertex3f(1,1,0);
   glTexCoord2f(0,1);glVertex3f(-1,1,0);
  glEnd();       
    glPopMatrix();
 glDisable(GL_TEXTURE_2D);

    glutSwapBuffers();
}
void idle()
{
 rot++;
 glutPostRedisplay();
}
int main()
{
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("0161081_hw8");
glutDisplayFunc(display);
glutIdleFunc(idle);
//Texture image file by OpenCV
IplImage * img=cvLoadImage("images.jpg");
 cvCvtColor(img,img,CV_BGR2RGB);
//Texture image file by OpenGL
 glEnable(GL_TEXTURE_2D);
 glGenTextures(1,&id);
 glBindTexture(GL_TEXTURE_2D,id);
 glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_LINEAR);
 glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_LINEAR);
 glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
 glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
 glTexImage2D(GL_TEXTURE_2D,0,GL_RGB,img->width,img->height,0,GL_RGB,GL_UNSIGNED_BYTE,img->imageData);
//Texture End
    glutMainLoop();

cvNamedWindow("00161081");
cvShowImage("00161081",img);
cvWaitKey(0);
return 0;
}

4.旋轉地球:



程式碼:
#include <GL/glut.h>
#include <opencv/highgui.h>
#include <opencv/cv.h>
GLUquadric *quad=NULL;
GLuint id;
float rot=0;
void display()
{
 glEnable(GL_DEPTH_TEST);
 glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
 glEnable(GL_TEXTURE_2D);
 glBindTexture(GL_TEXTURE_2D,id);
    glPushMatrix();
        glRotatef(60,1,0,0);
        glRotatef(rot,0,0,1);
        gluQuadricTexture(quad,true);
        gluSphere(quad,1,30,30);
  glEnd();       
    glPopMatrix();
 glDisable(GL_TEXTURE_2D);

    glutSwapBuffers();
}
void idle()
{
 rot++;
 glutPostRedisplay();
}
int main()
{
glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
glutCreateWindow("0161081_hw8");
glutDisplayFunc(display);
glutIdleFunc(idle);
//Texture image file by OpenCV
IplImage * img=cvLoadImage("images.jpg");
 cvCvtColor(img,img,CV_BGR2RGB);
//Texture image file by OpenGL
 glEnable(GL_TEXTURE_2D);
 glGenTextures(1,&id);
 glBindTexture(GL_TEXTURE_2D,id);
 glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_LINEAR);
 glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_LINEAR);
 glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
 glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
 glTexImage2D(GL_TEXTURE_2D,0,GL_RGB,img->width,img->height,0,GL_RGB,GL_UNSIGNED_BYTE,img->imageData);
//Texture End
    quad=gluNewQuadric();
    glutMainLoop();

cvNamedWindow("00161081");
cvShowImage("00161081",img);
cvWaitKey(0);
return 0;
