Newbie Question: World Not Appearing

[jesuisme]

Hi,

I'm new to Vizard and I'm having a problem getting anything to appear in the application window. Here is the script I'm running:

---
import viz

viz.go()

mygantry = viz.add('gantry.wrl')
viz.clearcolor(0.0, 0.0, 0.0)
---

I've also attached the vrml file 'gantry.wrl'.

When I execute the script, the only thing I see in the application window is a black screen. I've opened the vrml file in another viewer, so I'm sure it works.

I must be missing something simple . Any help is appreciated.

Thanks,
