Week13 課堂作業, 許志遙

以前在畫茶壺時，大小為0~1之間，並且調整畫面比例會變掉，於是有了以下的方法......

#include <GL/glut.h>

void display(){

    glPushMatrix();

        glutSolidTeapot(100);

    glPopMatrix();

    glFlush();

}

int main(int argc, char** argv){

    glutInit(&argc, argv);

    glutInitWindowSize(800,600);

    glutCreateWindow("Camera");

    glutDisplayFunc(display);

    glViewport(0,0,800,600);

    glMatrixMode(GL_PROJECTION);

    glOrtho(-400,400,-300,300,-1000,1000);

    glMatrixMode(GL_MODELVIEW);

    glutMainLoop();

}

但是上訴的方法在手動調整視窗的時候茶壺又變形了，於是又有了下面的方法

#include <GL/glut.h>

void display(){

    glPushMatrix();

        glutSolidTeapot(100);

    glPopMatrix();

    glFlush();

}

void reshape(int w, int h){

    glViewport(0,0,w,h);

    glMatrixMode(GL_PROJECTION);

    glLoadIdentity();

    glOrtho(-w/2,w/2,-h/2,h/2,-1000,1000);

    glMatrixMode(GL_MODELVIEW);

    glLoadIdentity();

}

int main(int argc, char** argv){

    glutInit(&argc, argv);

    glutInitWindowSize(800,600);

    glutCreateWindow("Camera");

    glutDisplayFunc(display);

    glutReshapeFunc(reshape);

    glutMainLoop();

}

加入計時器，自動轉

#include <GL/glut.h>

float eyeX=-100, eyeY=80, eyeZ=-200;

    glPushMatrix();

        gluLookAt(eyeX,eyeY,eyeZ, 0,0,0, 0,1,0);

        glPushMatrix();

            glutSolidTeapot(100);

        glPopMatrix();

    glPopMatrix();

    glFlush();

    glLoadIdentity();

}
