#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;

void display(){

    GLfloat pos[] = {0,0,200,0};

    glLightfv(GL_LIGHT0, GL_POSITION, pos);     ///打燈光

    glEnable(GL_LIGHT0);

    glEnable(GL_NORMALIZE);

    glEnable(GL_LIGHTING);

    glEnable(GL_DEPTH_TEST);

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

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

        glPushMatrix();

            glutSolidTeapot(100);

        glPopMatrix();

    glPopMatrix();

    glFlush();

}

void motion(int x, int y){                    ///eye-移動

    eyeX=-400; eyeY=300-y;

    glutPostRedisplay();

}

void reshape(int w, int h){

    glViewport(0,0,w,h);

    glMatrixMode(GL_PROJECTION);

    glLoadIdentity();

    gluPerspective(90,w/h,0.001,1000);

    glMatrixMode(GL_MODELVIEW);

    glLoadIdentity();

}

void timer(int t){                          ///計時

    glutTimerFunc(20,timer,t+1);

    eyeX+=2;

    if(eyeX>300) eyeY+=4;

    glutPostRedisplay();

}

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

    glutInit(&argc, argv);

    glutInitWindowSize(800,600);

    glutCreateWindow("Camera");

 依網址jsyeh.org/3dcg10下載標示的兩個檔案，提供參考用！

打開老師給的windows資料夾，打開裡面的Projection執行檔，試著轉動上面的數字可以發現人物會隨著數字而改變方向、大小、角度、胖瘦！

 開啟code blocks後，把打光的程式碼先複製起來！

接著寫下這些程式，可以創造出我們自訂的視窗大小
