The Star Wars spinoff The Mandalorian is a great example of a new wave of cinematic production. All of the sets and backgrounds are done as computer graphics displayed onto a big screen behind the actors.
As the camera moves, the virtual set moves accordingly, creating the illusion of a coherent 3D world. The light from the virtual set spills onto the actors, creating a compelling illusion that the actors are situated in that world.
Right now this is all very expensive, which is generally the case for new production technologies. I wonder how long it will be before the equivalent of this capability will go down in cost to the point where it is accessible to consumers.
At some point, this sort of virtual world visualization will become available to the equivalent of today’s Zoom users and YouTube posters. It will just be taken for granted that if you have a computer or SmartPhone, you will be able to believably situate yourself into a world of your choosing, for all the world to see.
At some point it will no longer be possible to know whether somebody is actually in the environment you see on the screen. This will have all sorts of implications, both beneficial and harmful.
I, for one, hope it gets used by the Light side of the Force, not the Dark side.
