概要：glVertex*

$ cd ../GLUT/glutDisplayFunc/
$ python2.5 -i glutDisplayFunc.py 
['glutDisplayFunc.py']
>>> print glVertex.__doc__
Choose glVertexX based on number of args
>>> print glVertex2d.__doc__
glVertex2d( GLdouble(x), GLdouble(y) ) -> None
>>> print glVertex3d.__doc__
glVertex3d( GLdouble(x), GLdouble(y), GLdouble(z) ) -> None
    

        
    




    
事例：図形を描く

    

$ python2.5 glutDisplayFunc.py -s2



def ex_2():
    ex_glutDisplayFunc(GLUT_RGB, display_2)

def display_2():
    glClear(GL_COLOR_BUFFER_BIT)
    glBegin(GL_LINE_LOOP);             # 折れ線を閉じる
    glColor3d (0.0, 1,0, 0,0)
    glVertex2d(-0.5, -0.5)
    glVertex2d( 0.5, -0.5)
    glVertex2d( 0.5,  0.5)
    glVertex2d(-0.5,  0.5)
    glEnd()
    glFinish()
