I just want to get the list of viewpoints to put in a drop down list so I can choose from the list and set the corresponding viewing transform. I probably want the Viewpoint node, but started with the TransformGroup call getViewGroups as I found it first. I am happy to get a handle on which ever one provides the viewpoint names and transforms.
I am currently doing something like Viewpoint[] views = null; views = VrmlSceneObj.getViewpoints(); int len = VrmlSceneObj.getViewpoints().length; view gives an out of bound index exception when accessing index 0, ie views[0] or views.get(0) and the 'len' variable = 0 after this call. Hopefully this isn't just my lack of java expertise. We will be arriving Sunday and will try to catch up with you at one of the events. -brett Giles wrote: > brett wrote: > > >Yes, I think it is the original loader that I have retrieved.
