WorldViz User Forum - Vizard AR problem

I'm not exactly understand what you are referring but if you want to something disappear when the marker is not shown you have do something like this:

Code:

import viz

viz.go()



#Add ARToolkit extension

ar = viz.add('artoolkit.dle')



#Create camera using first available webcam

camera = ar.addWebCamera()



#Create matrix marker

marker = camera.addMatrixMarker(0,width=1000)



#Add avatar model and set state 1

avatar = viz.add('vcc_male.cfg')

avatar.state(1)



#Link avatar model to marker sensor

viz.link(marker,avatar)



#Method that update if the marker is visible

def updateVisible():

        if marker.getVisible():

                avatar.visible(viz.ON)

        else:

                avatar.visible(viz.OFF)



vizact.ontimer(0,updateVisible)

I hope is that what you need
