Now you are knowing, I deal with a kind of experimental framework for what I call “Simple Multiuser Scenes” (SMS).
Professional flight simulators having what is called “tiles” to represent the surroundings of the scene (mountains, cities, rivers and so on), where Web3D Consortium has the results of the work group “X3D-Earth” to deal with modelling such tiles.
Now, when we think of flat “tiles” that are put together to create a curved surface of the earth,
what about flat “modules” that are put together to create a curved solar system or even a curved galaxy or a curved universe.
Where “flat” denotes validity of the SRT (special relativity) and “curved” means the presence of space warp according to ART (general relativity).
