IVEx file extenstion unrecognised.

[sindi]

Can anyone assist? I am currently learning vizard using the teacher in a book tutorial and experiencing a problem with images that have an IVEx extenstion , vizard 3.0 currently installed in my desktop cannot recognise the file extension.

This is the code I was running:
The original code is on page 27 of "Vizard Teacher in a book"

import viz
viz.go()
#Put the viewpoint in a good point to see the texture squad
viz.MainView.setPosition(0,.68,-1.3)
#Add a model and grab one of its children to put textures on
model = viz.add('art/window.IVEx')
window = model.getChild('glass')

Here is the error shown by vizard:

Traceback (most recent call last):
File "<string>", line 11, in ?
File "Modelling.py", line 8, in ?
model = viz.add('art/window.IVEx')
File "C:\Program Files\WorldViz\Vizard30/python\viz.py", line 8320, in add
raise ValueError, 'Unrecognized file extension: '+fileType
ValueError: Unrecognized file extension: IVEX

Could you please advise me how to go about enabling Vizard to recognise the IVEx file extension.

These are encrypted files not meant to be edited or used in other programs. If you want to use the resource in another Vizard script don't include the x in the file extension. For example:
import viz
viz.go()

window = viz.add('art/window.ive', pos = [0,1,3])
