This is a image sequence, creating a VR is one of the more complicated components we have ever created - so your work is cut out for you.
Basically, you set the _xmouse position when the viewer presses, then constanty monitor the change in direction - then transfer that to a 16 frame movieclip that jumps to the proper frame.
I'm sorry, I don't have a simple expanation for you.
We will be introducing a component set very soon that will include both interior and exterior VR's - all you'll have to do is tell the component where the images are on the server and the component will do the rest.
Just a side note, Nissan is using CGI technology to generate these images. We spent some time on a similar project for Chrysler - too bad these guys can't figure out how to create a sharp image at low file sizes. It's not that complicated...
They are using flash and not QT I think, so I figure its only like 36 frames that are in a movie clip and the on_drag just uses coordinates to go between frames...that's how I would build it....just don't know the code. It looks to be pretty simple.
