02163051_邱冠程_Week05

設定正方形(回顧上星期)

讓他移動(但是是平行)

一樣是移動，但是可以改角度

增加程式，然後利用滑鼠讓他轉動

#include <GL./glut.h>

float angle=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT);

    glPushMatrix();

        glRotatef( angle,  0, 1, 0.5); ///起始角度

    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);
