[Python] OpenGl Rendering the Line To Infinity(Only supposed to go to (20, 20)

[xelapond]

Hello,

Experimenting with PyGlet OpenGl rendering, and I wrote this simple script. What it is supposed to do is render a line from (0, 0) to (20, 20). The goes off the screen though, and I can assume goes for a much longer distance(infinity?).

Here is the code:
import pyglet
from pyglet.gl import *

def drawLine(points, color=(1, 1, 1)):
p1, p2 = points[0], points[1]
glLineWidth (10.0)
glColor3f(*color)
glBegin(GL_LINES)
glVertex2f( p1[0], p1[1] )
glVertex2f( p2[0], p2[1] )
glEnd()
glLineWidth (1.0)


win = pyglet.window.Window(600, 600)

while 1:
win.clear()
drawLine(((0, 0), (20, 20)), (.5, .5, 1))
win.flip()


Anyone have any idea what it is doing?
