[emily800326]

i use the camera to read my ar-code.
but the panel turn black , and i can't see my code.
can someone tell me what the problem.
(when i run another code,also have this problem.)

import viz

viz.go()


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

m0=camera.addMatrixMarker(0,width=50)
modle1=viz.add('box.obj')

links=viz.link(m0,modle1)
modle1.setScale(0.05,0.05,0.05)
modle1.texture('')

Are you saying the graphics window is just black? Do you get any error message in Vizard? If not, perhaps the model is obscuring the view. Can you see the webcam output when you run the following?
import viz
viz.go()

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

Warning: TextureRectangle::apply(..) failed, texture rectangle is not support by your OpenGL drivers.

You can try updating the drivers.
