Cesium and a Greyhound server (Massive Point Clouds)

Hello,

I have been looking everywhere but it seems there is no documentation about how to reproduce the NYC example (http://cesium.entwine.io/?resource=nyc).

I have indexed my Point Cloud data with entwine (with cesium parameter) and it's now streaming through a local Greyhound server (hosted on VMbox).

But I don't understand how to hook up the Greyhound server with Cesium so that the spatial request go through the server.

Getting this :

- "?s=http://xx.xx.xx.xx:8080/&r=Datafolder"

to work with this (I guess?) :

- “var tileset = viewer.scene.primitives.add(new Cesium.Cesium3DTileset({
    url : ‘http://xx/
}));”

It may seem dumb but I was not able to make it work. If someone have any idea of what I should/can do !
