Hi, no, it contains an array, just click on the small arrow to see the children.

Hi Yvonne,

> just wrote a very small test that instead dumps a given scene as JSON to the Browser console (ignore __proto__, this is always there in JS, should be skipped when serializing). Here is the example (click the “dump” button and see the result in the console): http://www.x3dom.org/x3dom/test/functional/flipper.html

This is interesting. But the "children" container ins "Scene" is empty ?!?

Best regards

> This is because I think, it might be easier to start the other way round: the X3DOM runtime already has all information for creating some test JSONs. The export could then be refined/optimized based on some tests and from that, a first and easy to integrate draft could be derived. What do you think?
