Connect collections information and 3D view

[EdwardMoyse]

If you click on a cluster, track etc, and the collections view is open, that object should be highlighted there. And vice versa.

It would also be great to have an option (in the collections panel?) to zoom to that object.

I don't think we have a unique identifier for each event item (cluster, track etc). We need something like that in the userData to identify a certain event item so we can pick it up from the collections info.

Was finally able to make it work, only for tracks for now (could make it work with the other objects the same way). Since I mentioned we needed some kind of ID to identify the event object by, for now, I am attaching it to the tracks manually like this:
PhoenixObjects::getTrack(trackParams: any): Object3D

const splineObject = new THREE.Line(geometry, material);
splineObject.userData = trackParams;
* splineObject.userData.item_id = Math.floor(Math.random() * 100).toString() + Date.now();
splineObject.name = 'Track';

I think something like this is safe enough for us.

Have a look:

WDYT @EdwardMoyse @emiliocortina ?

Making a unique id like this should be fine I think - elsewhere we have used the index of the object (e.g. track) in its collection, but perhaps this isn't so convenient here?

It looks very nice! Would it work both ways? i.e. if I clicked on a track in the collection list, would it be highlighted in 3D?

Do you mean the uuid by index? If so, then yes. It might be more convenient. I was testing things with the current implementation.

I haven't done that yet. But making it work the other way around will be much simpler, however I am not sure how we can highlight the tracks since that doesn't work right now (because of the Line geometry. I will look into how we can move the camera to the object for now so we have something to start with.

Yes. This shoudl be generally safe I think - in fact, this is what we do in ATLAS with our general reconstruction software ... links between objects are ("Collection name" : index )

Of course you're right that highlighting tracks is a general issue - I guess we could change the colour of that track? But it would be best to fix it properly.

Moving the camera to look at an object but it doesn't work for tracks and hits. So I was wondering if we should switch to outlines? Or its also possible to keep both the "Go to" and "Highlight" option from the collection panel.

Hi,

I forgot to give an update on this. I added the option to highlight.

The "Look at object" option doesn't work for tracks and hits. I will look into what I can do about it.
