Hello there,
I was wondering if there’s a way to only bring in a small part of a location entered instead of it importing the entire world in AR.
For more clarification what my intention is for the user to enter a location (lon, lat) and get a small plane (maybe a small square) that contains part of the 3d map of this location, is that possible??
I’ve tried a-lot of approaches but to no avail and it normally lags and takes time as it continues loading the entire world map.
HI @YasmeenShaaban, welcome to the community!
We have a few features that allow you to hide parts of tilesets and/or exclude tiles completely from loading.
The first is polygon clipping, which uses a spline to exclude everything outside (or inside) of your drawn polygon. We have a tutorial for that on our website.
Secondly, if you’re comfortable with writing scripts in C#, you can implement tile exclusion behavior using the CesiumTileExcluder interface. You can use this to, for example, exclude tiles outside of a specified radius, or any tiles that fall outside of a box mesh. There’s an example in the description of this PR: https://github.com/CesiumGS/cesium-unity/pull/248.
Let us know if that helps!
