<node3d>.getChildren() subtleties

I am trying to poll an object loaded from an ive file for it's children. The object always returns an empty list from getChildren(). However, if I use getChild('DVD') (one of the children), it returns a viznode. So I am wondering if there is some subtlety I am missing, possibly something to do with getChild searching deeper than immediate children?

So, the code looks something like:

Code:

obj = viz.add('ObjectsTest.ive')

print obj.getChildren()

(returns [])

print obj.getChild('DVD')

(returns viz.VizNode(35))

The node3D.getChildren command will return a list of the immediate Vizard node3d objects that are below that node. It will not return a list of the underlying scene graph nodes.

When you use the node3D.getChild command a new node3d object is created.

You can use the .getNodeNames command to retrieve a list of names of the scene graph nodes underneath the Vizard node:

Code:

model = viz.addChild('gallery.ive')



print 'Model contains the following scene graph nodes:'

for name in model.getNodeNames():

        print ' ',name

Thanks, that was just what I was looking for!
