I have to make 3D Grid for Geofencing with drone, so I made a 3D Grid With Entity boxes, But That performance was terrible, so I wanna Know Something good to make 3D Grid or How to Know Box Contains Building or Terrain
this pic is what I wanna do
Welcome to the community 
Your use case seems amazing! I would love to see the final product when it is complete.
My first idea would be to use an Entity box. If implemented correctly, I would not expect the performance to be demo-breaking. If you send over your current implementation, I would be happy to take a look at your implementation.
Another possible solution would be to use a CZML object. This might have better runtime performance. Here is a demo of how to create a translucent Cesium ellipse that should help you get started.
You can check out the CZML spec for more details
Let me know if you have any other questions or concerns.

Hi! Example of boxes (1000 of them in a grid). Performance seems very good:

Performance is crazy good 
Here with 27 000 boxes and no lag on frame rate at all:
Around 100k boxes the creation starts getting really slow though… it almost hits some non-continuity point, takes like 5 minutes to create the boxes. But still performance in rendering is good.

Looks amazing! 
100k boxes would maybe be a little bit overwhelming but still very cool. I am so happy that we found a robust solution. @Gwondori be sure to check this out.
Let me know if anything else comes up!
