[1.14] Displaying and rendering the view of a remote position

[DavidM]

I am trying to make a camera-like block. There is a camera block and a screen block.

I would like to place the camera block and the screen block in different location, and let the screen block render what the camera sees in the direction the camera is pointing.

I would like the camera block to display the view in first person, as if it is what a player sees at the position of the camera.

What would be the best way to achieve this?

 

Answers regarding 1.12/1.13 are also welcomed, but 1.14 is more preferable .

The Tardis mod does something like this. I think that you should set the renderViewEntity to an entity in your camera's position, render everything to a frame buffer, set the renderViewEntity back & then render your frame buffer to the main mc one.
