Well, it looks like your a webpage threw up multiple levels of structured data in your browser. Wonderful 3-dimensional throw up. Mozilla Firefox version 11 is out and with it a new developer tool that allows you to view a website’s Document Object Model (DOM) in the beauty of three dimensions. Fancy a look?
Firfox 3D DOM Viewer
The idea with is that by providing the 3D visualization, web developers can see how complicated the structure of a website is and make changes to simplify accordingly. So, why couldn’t the same be done for 3D models? (Granted you’re using a history-based, hierarchical modeling system.) Thing is, if we’re the ones creating the models, we know how complicated they are and could (likely) care less. But make this a model generated online by xml/css and you’ve got 3D visualization of your 3D visualization.
