                                         1.方塊3D

#include<GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT);

    glBegin(GL_POLYGON);

         glColor3f(1,0,0);

         glVertex3f(0.1,0.1,0.8);

         glVertex3f(-0.1,0.1,0.8);

         glVertex3f(-0.1,-0.1,0.8);

         glVertex3f(0.1,-0.1,0.8);

     glEnd();

    glFlush();

  

}

int main(int argc, char **argv[])

{

    glutInit(&argc, argv);

    glutCreateWindow("02160243");

    glutDisplayFunc(display);

    glutMainLoop();

}

                                         2.方塊旋轉

#include<GL/glut.h>

float angle=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT);

    glPushMatrix();

       glRotatef(angle,0,1,0);

       glBegin(GL_POLYGON);

         glColor3f(1,0,0);

         glVertex3f(0.1,0.1,0.8);

         glVertex3f(-0.1,0.1,0.8);

         glVertex3f(-0.1,-0.1,0.8);

         glVertex3f(0.1,-0.1,0.8);

     glEnd();

   glPopMatrix();

   angle+=0.01;

   glFlush();

  

}

int main(int argc, char **argv[])

{

    glutInit(&argc, argv);

    glutCreateWindow("02160243");

    glutDisplayFunc(display);

    glutIdleFunc(display);

    glutMainLoop();

}

                                         3.讓3D方塊旋轉

#include<GL/glut.h>

float angle=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT);

       glVertex3f(0.1,-0.1,0.8);

       glVertex3f(0.1,-0.1,-0.8);

    glEnd();

    glPopMatrix();

    angle+=0.01;

    glFlush();

}

int main(int argc, char **argv)

{

    glutInit(&argc, argv);

    glutCreateWindow("02160243");

    glutDisplayFunc(display);

    glutIdleFunc(display);

    glutMainLoop();

}

                                         4.滑鼠移動方塊

#include<GL/glut.h>

float angle=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT);

    glPushMatrix();

       glRotatef(angle,0,1,0.5);

       glBegin(GL_POLYGON);
