Did anyone know about 3D Rig?
How it work, please?
Not sure which one you are talking about. Googled "3D Rig" and there were 15,000,000 hits. Many different models/designs out there.
asbroadcast, here is a link from the recent Videomaker magazine about a 3D rig:

This was posted a while back as well. The link goes into some explanation for this type of rig.
