hi guys,
i’d like to build my own 3D tracking device for a bluescreen shot. does anyone know what that stick/cross with those ping pong balls sticking at each end is called? i’ve seen it a hundred times but i can’t say what it’s called, except “6-ping-pong-ball-stick-thingy” 😀 in case anyone knows how to build such a thing (dimensions, material, what to be aware of etc.), let me know. even if your information is very rough it’ll definitly be helpful.
thx for your help
Guido
