 ***作業/考試複習

1.先畫個正方形

#include <GL/glut.h>

 void display()

 {

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glRectf(0.5,0.5,-0.5,-0.5);

int main(int argc,char**argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutInitWindowSize(600,600);

    glutCreateWindow("Week13 rect TRT");

    glutDisplayFunc(display);

    glutMainLoop();

}

2.加上手臂

#include <GL/glut.h>

    glRectf(0.5,0.5,-0.5,-0.5);///身體

    glPushMatrix();

        ///glTranslatef();

        ///glRotatef();

        glPopMatrix();

    glPopMatrix();

    glutSwapBuffers();

 }

int main(int argc,char**argv)

{

    glutInit(&argc, argv);
