ECS(DOTS) && Cesium for unity3D

Is there anyone trying to use ecs ?
Has anyone tried using DOTS such as entity for Cesium development?(GitHub - Unity-Technologies/EntityComponentSystemSamples)

Cesium for Unity uses a number of MonoBehaviours. But I don’t know of any reason that other objects in your scene couldn’t be entity-based. I haven’t tried it, though.

Hi.

I am working on vector data rendering on terrain.

in order to do this. I have to write effective logic for camera frustum culling for shadow volume meshes.

so I am considering to use DOTS for quad tree culling. check this asset below. If you want to check out proper example then this will be good sample for you.
