- Thu, 6 Dec 2007 at 3:18 pm · Sandio Tech releases their new Sandio 3D Game O2 mouse, with six degrees of freedom (6DOF) in 3D environments. The mouse looks like an ideal 3D 6DOF controller for me, as it would be more intuative to the production work-flow that I’ve mastered or grown accustomed to. I’ve tried just about any kind of peripheral you can imagine that’s supposed to make things easier, from track-balls, to pen-tablets and touch-screens (like Wacom) — I’ve always been faster and more efficient with a mouse and short-cuts. · (0)
