Working in 3D has never been easier. Grab hold of your designs with an HP Spaceball 4000 FLX motion controller and high-performance HP workstation, you can simultaneously pan, zoom and rotate 3D models and 3D viewpoints as you build, modify and inspect your design and animations - right within the active design session. A Spaceball provides 6DOF (6 degrees of freedom) motion control. You simply push, pull or twist the Spaceball's PowerSensor ball for smooth and dynamic X, Y and Z axis rotations and translations, just as if you were actually holding your model in your hand. The PowerSensor ball moves, providing ease of use. It's a natural and intuitive method for moving and viewing 3D designs. With the HP Spaceball, you are able to focus on the model - not on the method required to move the model.
