can we divide/brake whole world in 1*1 km(sqr.) area? and after that we are able to select every area
Hi @Aman_Srivastava, welcome to the forum.
I can’t think of an easy way to break up the world like you suggest, but that doesn’t mean it’s not possible. If you want to try to develop your own solution for this, there are a few things you may want to keep in mind.
Terrain like Cesium World Terrain is streamed into Unreal using 3D Tiles. With Cesium World Terrain, they’re generally square, but the tiles don’t stay a consistent size. As you move closer to a tile, it will refine into several smaller tiles, and the opposite occurs when you move away from a tile.
You can select a tile by double-clicking on a part of a tileset in the editor:
But you can’t select just part of a tile, so it would be very difficult to partition the world into precise 1x1 squares.
Also, due to the curvature of the earth, it wouldn’t map very neatly into perfect squares, especially as you move away from the world origin.
However, if you try to implement something like this, please share how it goes - any information you learn on this could help a future developer looking to do the same thing.
Not exactly what you were asking for, but this tutorial might be of help - Building Global Scenes with Georeferenced Sublevels – Cesium
