pincushion distortion

[whj]

Hi,

I have trouble to get pincushion distortion with this simple code. Can somebody point out what I'm missing? Thanks a lot!

import viz
import vizlens
viz.go()


pincushion = vizlens.PincushionDistortion() 
viz.add('tankmaze.wrl')

That is working correctly. You can see how the image changes when you press the spacebar.

import viz
import vizlens
viz.go()

viz.add('tankmaze.wrl')

vizact.onkeydown(' ',vizlens.PincushionDistortion)

Thank you Jeff. But I guess my graphics card doesn't support this function. I'm wondering what is the limit of my graphics card. It works well on other applications.

THANKS!
