Is possible to get dimensions of camera collider?

How get dimensions of camera collider?
Also if possible how to change those dimensions?

I think this is controlled by the ScreenSpaceCameraController:

https://cesiumjs.org/Cesium/Build/Documentation/ScreenSpaceCameraController.html?classFilter=ScreenSpace#minimumCollisionTerrainHeight

It’s based on the height to terrain rather than a specific shape of a collider, which you can tweak. Does that help?

Yes, I think that help. Thank you.
