Each point has its own properties (e.g. temperature) in the batch table which can be used to style each single point individually.

But is it possible to request the properties of a clicked point, like the building properties in the New York 3D Tiles Feature Picking sandcastle example?

This is not currently possible, but it is an open feature request: https://github.com/AnalyticalGraphicsInc/cesium/issues/7408

I found this class (https://cesium.com/docs/cesiumjs-ref-doc/Cesium3DTilePointFeature.html), still experimental, but it has the function i need to use:
getProperty(name)

``

But as far as I could read out of the issue #7408, it is the pick-action on a Point feature that isn’t implemented yet?

It’s specifically the fact that the data is sent to the GPU and deleted on the CPU side, so it can’t be retrieved. For this to work a copy of the data would need to be kept on the CPU side.
