(1)3D方塊

#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("02160615");

    glutDisplayFunc(display);

    glutMainLoop();

}

 (2)讓方塊轉動

#include <GL/glut.h>

float angle=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT);

    glPushMatrix();//備份Matrix

        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();//還原Matrix

    angle+=0.01;

    glFlush();

}

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

{

    glutInit(&argc, argv);

    glutCreateWindow("02160615");

    glutDisplayFunc(display);

    glutIdleFunc(display);

    glutMainLoop();

}

(3)3D方塊旋轉

#include <GL/glut.h>

float angle=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT);

    glPushMatrix();//備份Matrix

        glRotatef(angle,0,1,0.5);

        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();

        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();

        glBegin(GL_QUAD_STRIP);

            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);

            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();//還原Matrix

    angle+=0.01;

    glFlush();

}

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

{

    glutInit(&argc, argv);

    glutCreateWindow("02160615");

    glutDisplayFunc(display);

    glutIdleFunc(display);

    glutMainLoop();

}

(4)mouse轉動

#include <GL/glut.h>

float angle=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT);

    glPushMatrix();//備份Matrix

        glRotatef(angle,0,1,0.5);

            glVertex3f(0.1,-0.1,0.8);

        glEnd();

        glBegin(GL_POLYGON);

            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();

        glBegin(GL_QUAD_STRIP);

            glVertex3f(0.1,0.1,0.8);

    glFlush();

}

int oldx=0;

void motion(int x,int y)

{

    angle+=(x-oldx);

    oldx=x;
