It wasn't even new when Microsoft Kinect did it... let's see... 12 years ago.
Kinect point cloud was a total mess, never worked with more than a few cameras and had a LOT of restriction and artifacts, what I meant by impressive, imagine a moving 6 camera kinect with clean signals, that doesn't fail on specific texture or reflection because it track in 4D + AI.
Probably the people downrating are the same thinking the Tesla FSD AI is a kinect contraption.
