Good to hear from you. You’ll find a whole bunch of iPad enthusiasts in this Forum who are only too willing to help other iPad owners and to hear of their experiences. Don’t be afraid to post any questions you may have or use the ‘Search’ button near the top of the Forum web page. I usually find I discover one new interesting and useful piece of information about my iPad every day - and often not even what I was looking for!!
With regard to providing the capability for a 360 degree rotation effect, the only apps that I'm familiar with are those that are clients for mechanical 3D design packages - such as AutoCAD. Several of these design packages have iPad clients that can read the design files and display the object being designed in 3D, though they are unable to edit the underlying design. But I suspect the effort required to enter the information that you have in mind to display into these programs would be more than you're willing to expend.
In fact, that 360 degree effect from the Apple web site does not even display correctly on my iPad.
Hope to hear from you soon with your thoughts about the iPad.
Have fun and enjoy your iPad
