While poking around the site of that brilliant GLSL iPad app, among many wonderful goodies (see link below), I found this excellent demo of SpaceNavigator, the 3D control hardware.
Got my SpaceNavigator in the mail today. It’s a 6-dof HID that works great with Blender. I threw together this test scene to get to grips with flying, it certainly has a slight learning curve but is well worth it. The speed you can navigate around your scene is fantastic and is perfect for finding new camera angles and planning/recording camera paths.
I have one of these, and played a bit with it using Processing. I’m curious – who out there has one? How do you use it / how do you map its 3D parameters? What tools do you use it with?
