ClassificationPrimitive to highlight specific tiles only

I would like to draw a heat map over region with multiple overlapping tiles (primitives). Is it possible to ClassificationPrimitive highlight specific primitive only?

From my understanding, classificationType option allows highlighting terrain only or all visible tiles only or both.

Using ClassificationPrimitive sample below. Let’s pretend each tree is from different tiles (it’s not in the sample). Is it possible make the same ClassificationType (orange) to highlight specific tree only?

I looked into ClippingPlane to find away disable render outside of said primitive, but it doesn’t seems to be what I’m looking for.

Thank you in advance

I am not aware of a way to classify specific tilesets only using Classification primitive. However, if the tree was a pickable feature of the tileset (example of feature picking here: Sandcastle | CesiumJS ), you could do a per-feature highlight of the trees or other objects for example.

If you wanted to highlight everything in one tileset, you could apply a style to the tileset, unfortunately both of these options lose the “draping” visual of ClassificationPrimitive but if you wanted to only highlight the tree then this may not be a deal breaker.

Does that work for your use case?
