Trouble Adding Cesium 3d Tiles to HelloWorld.html...

Hi there,

Just trying to add Cesium 3d tiles to the helloworld.html example (via IIS):

Hello World! @import url(../Build/Cesium/Widgets/widgets.css); html, body, #cesiumContainer { width: 100%; height: 100%; margin: 0; padding: 0; overflow: hidden; }


Getting this error:

HelloWorld.html:24 Uncaught TypeError: Cesium.Cesium3DTileset is not a constructor

Am I missing something?

Thanks in advance,


Hi there,

Are you working off the 3D-tiles branch? 3D-tiles has not yet been merged with our main Cesium releases. What version are you using?

Where would one find the 3D-tiles branch? I was unable to find it on the main download site.

Hi Peter,

The 3d-tiles branch is here in out github repo – you can clone or download a zip here:

Hope that helps!

Hi Rachel,

Thanks for the update. Is this branch still active? I did get a 404 error.



3d-tiles has been merged into master! So you can just use the master branch.

If you want to use a pre-release without building it yourself, you can use this build:

Thanks! That’s good news.


OK, I now no longer receive an error message in the browser, however no data is rendered. I’ve attached the data should anyone like to give it a whirl?

I tried loading the model but it seems like the some of the geometry has degenerate triangles and a normalization error is being thrown. Is it possible to fix up the source data?
