RapidForm supports new external hardware, the 3D Motion Controller. Using a 3D motion controller, you can intuitively zoom, pan and rotate your 3D model as naturally as if you were holding it in your hand. Also, RapidForm allows you to designate functions for each of the eight programmable buttons on the 3D motion controller (View >> Customize 3D Motion Controller).
