how to show only part of czml file

I have one .czml file with 55 000 object.
I want to divide this file in smaller pieces according to their geographic location in smaller groups of enities (in small squares).

Is this possible in Cesium?

Is there any kind of filter on .czml file?

Hello,

It sounds like what you are looking to do will be solved by the new 3D Tiles specification. It is a specification for streaming massive datasets using LOD.

You can learn more about 3D tiles here: https://groups.google.com/d/msg/cesium-dev/tCCooBxpZFU/7hxT_E4pGgAJ
