like implemented in the above web viewer:
* move trackball forward / backward / left / right (w / a / s / d keys) for 'walking'
* pan view left / right / up / down by moving the mouse, while keeping the horizon level and position unchanged
there could be an option added to move the trackball up and down with the keys. .....
For scanned objects, the current style of navigation is very convenient but it is less nice to use
to look around in a scanned room . This alternative navigation style like is implemented in the website
would be nicer to do that...
thnx !
