Can we produce true 3D holograms yet? Do we currently have true 3d animated holograms yet? Images that we can walk around and see as 3d? I'm pretty sure we have this for still objects but I've seen plenty of videos of animated concert holograms and they are only looking face on at the stage.
It depends what you regard as "true 3d" but there is a technique called "Light Field Display" which has been in development for some time now. Its essentially still a 2D screen but you can walk around and look at it from different angle as if it were an actual 3d object.
