Thanks ! but when i have opened the tileset , i guess its encoded by CRC32 ,and when i added its url as below, it did not work var tilesetUrl = '../../../Specs/Data/Cesium3DTiles/Tilesets/NewYork/';

is there a way to get it in Json format as normal tilesets ?

This is the right place to download the 3D Tiles tileset for the OSM NYC extract. It is possible that it is out-of-date compared to Cesium's 3d-tiles branch.

@mramato if this is the case, can we update it?

That zip file is up to date, but all of the tiles are pre-gzipped and need to be served with Content-Encoding of gzip in order to be loaded by the browser. How you set this header depends on what server technology you are using for the data.

We should probably include a README and simple node-based server with the zip to make serving tyhe data easy. I'll keep this open and close it when that's done.

@mramato can you move this issue to another repo - even the Cesium 3d-tiles roadmap issue, https://github.com/AnalyticalGraphicsInc/cesium/issues/3241 - so we can keep this repo focused on spec issues?
