I want to create a stereo camera

from direct.directbase.DirectStart import *
from pandac.PandaModules import *

# Retitle the main window as the "left" eye
wp = WindowProperties()
wp.setTitle('left')
base.win.requestProperties(wp)

# Open a new window and title it as the "right" eye
w2 = base.openWindow()
wp.setTitle('right')
w2.requestProperties(wp)

# Move the eyes apart a little bit, and converge them both on a point
# 20 feet ahead.
base.camList[0].setPos(-0.5, 0, 0)
base.camList[0].lookAt(0, 20, 0)
base.camList[1].setPos(0.5, 0, 0)
base.camList[1].lookAt(0, 20, 0)
