[iTowns-user] Accessing features of a GeometryLayer

[Adrien Berthet]

Hi Chad,

I assume you are using a FileSource ? In this case, you can use layer.source.parsedData to access the FeatureCollection (which is an internal itowns format).

If you meant the ThreeJS objects, you can get them by setting a onMeshCreated to your layer, like in this case for example: https://github.com/iTowns/itowns/blob/master/examples/source_stream_wfs_3d.html#L189-L192
It allows you to access the mesh once it has been created, and you can even use this method with a stream.

Hope it helps a bit

Adrien

Objet : [iTowns-user] Accessing features of a GeometryLayer

How can I access features that were added to a GeometryLayer from a GeoJSON source? I have to pass in a ThreeJS Group to the GeometryLayer constructor, but that object ends up having no children so I’m not sure where the actual features end up in the scene.

To be clear, I’d like to be able to access individual ThreeJS objects that represent each feature in the layer. I don’t know if that’s how they’re created and added to the scene, but it seems logical since they can be different colors.

Thanks,
Chad
