Scene streaming for big environments

[mozhoku]

Scene streaming or aka "additive scene loading" could be useful for making large environments. We can make a script to support this feature.

What this does is simply it loads/unloads the environment around the player dynamically. This gives the users option to create large simulation environments and make it work with limited computer resources.

Here is an old video of me testing scene streaming with an large environment created with Citygen3D:

This feature also could be useful for small but detailed environments.

I tried conceptual to find a futureproof solution for this.

My findings so far.
Use Unity's high-precission-framework and projections into WGS 84.
So you can stream the complete planet and you have gps coordinates and an earth center in Unity.
arcgis sdk for unity and cesium have this already integrated.
Only tested arcgis so far. It alllows worlwide streaming of the osm daylight distribution base maps and osm buildings.
Then you can add an 3d mesh layer (streaming from streaming assets or server) of your city and place it to the real pos on earth.

This could be a general solution with lots of benefits.
