Type Error when loading 3D Tiles

[91raan1mpg]

Hi, I am trying to display a 3D Tileset with the Tile3DLayer and the Tiles3DLoader in Deck.gl, but in the web console I get the message:

Error: 3DTileLoader: unknown type {"as

The tileset can be rendered in a CesiumJS viewer.

What type is the error message referring to and should the type be specified in the loadOptions ?

It should not be too hard to narrow this down, it looks like a tileset json file is not being correctly detected. Or it is a json file but not a tileset json file.

Is your tileset available to enable maintainers to reproduce this issue?

The tileset is available under:

http://steinbeis-3dps.eu:8080/3DContainerTile/collections/NewYork/3DTiles/

The content is a tileset json file, does the URL has to end on tileset.json to be detected?

Hi @ibgreen ,

I am Joe, (@91raan1mpg colleague), In case you wanna test with the local tileset you may download our NYC-Manhattan 3D Tileset from this link
(We converted it from NYC 3D Buildings - DoITT.)

You are correct. At the moment it looks like we don't detect tileset files based on sniffing the content, so you either need to add a .json extension or provide a loader option to force the loader to interpret it as a JSON file, see:

https://github.com/visgl/loaders.gl/blob/master/modules/3d-tiles/src/tiles-3d-loader.js#L43

Effectively, the 3d tiles loader handles a mix of JSON and binary file formats.

I'll update the document with more details about how to use the loader.

Thank you for your help with the loader option, the tileset can be displayed now. But for it to work, the option has to be added twice.

   new Tile3DLayer({
            id: 'tile-3d-layer',
            data: data_url,
            loader: Tiles3DLoader,
            loadOptions: {
                '3d-tiles':{isTileset:true},
                isTileset:true
            }
   })

@91raan1mpg thanks for reporting the issue. I'll look into it today.

@91raan1mpg the double option issue is fixed in 8.1.7
