As I understand, that is a kind of platform that allows Esri I3S service to be rendered in Cesium and vice versa, 3dtiles in ArcGIS, correct?

I heard about it quite long time ago, but nothing since then. Only recently our client may have inclination to that, so we did a little research.

Still found nothing, even the demo link in the OGC doc([http://docs.opengeospatial.org/per/17-046.html](http://docs.opengeospatial.org/per/17-046.html)) is no longer available.

So is there anyone of the Cesium team familiar with this?

In the link above I do remember have seen a demo of I3S in Cesium, any ideas of how does it work would be great help.

Thank you

There aren’t any demos of i3s in Cesium that I’m aware of - although if anyone in the community has any links I’d be curious to see it.

Do you have a use case that 3D Tiles doesn’t do well?

Hello Omar,

Just in that OGC doc, it’s really long, some 82 pages on A4 paper if printed out, but worth reading.  
[http://81.169.187.7:9000/showcases/i3s#settingsTab](http://81.169.187.7:9000/showcases/i3s#settingsTab)

and a youtube video,to show what that links used to look like

[https://www.youtube.com/watch?v=SithZWHPgNQ](https://www.youtube.com/watch?v=SithZWHPgNQ)

also in that doc.

And no, 3dtiles is very good, sorry if you feel that way. It’s just our client have lots of pre-made models that already in I3S format. and we are trying to explore the interoperability of it.

Thank you.
