ARToolKit mirror

[skywalkerbr]

Hi every one!
How can I flip a image from a webcam like a mirror, for artoolkit?
I have this code:
import viz
viz.go()

#Add ARToolkit extension
ar = viz.add('artoolkit.dle')

#Create camera using first available webcam
camera = ar.addWebCamera()

#Create marker from pattern file
marker = camera.addMarker('ar/taca',width=1000)

#Add logo model
ball = viz.add('Taca_Fifa_AR.wrl',pos=(200,200,-400),cache=viz.CACHE_CLONE)
ball.setScale(0.1,0.1,0.1);

pic = viz.addTexture('Sb_Taca.jpg')


ball.texture(pic)


#Link logo model to marker sensor
viz.link(marker,ball)
ball.setPosition(200,200,0)

If you mirror the image, then the computed position of the markers won't match what is displayed on screen. Can you explain what you are trying to achieve?

Thanks for replying.
I want to mirror computed position of the markers too. So the effect will be the same as a mirror.
Like a "magic mirror" where the reality is augmented.
