Get all Assets / Scene Root?

[shivanangel]

I was wondering if there is a way of getting the root of the scene or all the assets that are loaded into the scene.

I'm writing a system that allows for adding models, textures, audio and placement of objects while we are in our CAVE and I'd like to save the results out. I know the save feature in vizard works on a viz.vizNode object, but is there a way to save out the current scene or a way of accessing all elements in a scene (scene graph) so I can export the information out myself?

I could store this information myself into the system, but given that it is already there in your app, I figured there might be a better way that manually recording everything myself.

Thanks,
George
