1.建造一個立方體

2.讓它旋轉

3.有兩個正方 點對點連在一起

變成正方體璇轉

4.增加可以滑鼠拖曳的功能

也還是可以自動旋轉喔喔喔

#include <GL/glut.h>

float angle=0;

static void display(void)

{

    glClear(GL_COLOR_BUFFER_BIT);

    glPushMatrix();

    glRotatef( angle, 0,1,0.5);//調整旋轉角度

    glBegin(GL_POLYGON);

    glColor3f(1,0,0);

    glVertex3f(0.1,0.1,0.8);//1-1

    glVertex3f(-0.1,0.1,0.8);//1-2

    glVertex3f(-0.1,-0.1,0.8);//1-3

    glVertex3f(0.1,-0.1,0.8);//1-4

    glEnd();

    glBegin(GL_POLYGON);

    glColor3f(1,0,0);

    glVertex3f(0.1,0.1,-0.8);//2-1

    glVertex3f(-0.1,0.1,-0.8);//2-2

    glVertex3f(-0.1,-0.1,-0.8);//2-3

    glVertex3f(0.1,-0.1,-0.8);//2-4

    glEnd();

    glBegin(GL_QUAD_STRIP);//把她縫起來(點對點)

    glVertex3f(0.1,0.1,0.8);//1-1

     glVertex3f(0.1,0.1,-0.8);//2-1

    glVertex3f(-0.1,0.1,0.8);//1-2

     glVertex3f(-0.1,0.1,-0.8);//2-2

    glVertex3f(-0.1,-0.1,0.8);//1-3

     glVertex3f(-0.1,-0.1,-0.8);//2-3

    glVertex3f(0.1,-0.1,0.8);//1-4

     glVertex3f(0.1,-0.1,-0.8);//2-4

    glEnd();

    glPopMatrix();

    angle+=0.01;

    glFlush();

}

int oldX=0;

void motion(int x,int y)

{

    angle+=(x-oldX);

    oldX=x;

}

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

{

    glutInit(&argc, argv);

    glutCreateWindow("02160323");

    glutDisplayFunc(display);

    glutIdleFunc(display);

    glutMotionFunc(motion);//mouse motion drag動作移動的韓式

    glutMainLoop();

}

今天上課頭好痛

快爆炸了
