Different errors with different 3d-tiles (b3dm)

[ikemarv]

Description

I have used different building data in b3dm format and get different errors except for one data source.

• My institution's own data with its own conversion tools: tileset-3d.js:481 A 3D tile failed to load: undefined Invalid attempt to iterate non-iterable instance. In order to be iterable, non-array objects must have a [Symbol.iterator]() method.
• Open Data of North Rhine-Westphalia (Germany) or Hanover (Germany), converted by pg2b3dm (converted data NRW: https://github.com/ikemarv/test-itowns-nrw/tree/master/apps/data/lod2_nrw ): No error, but buildings are not visible and it zooms into the Indian Ocean
• data of Manhattan by JoeThunyathep from https://github.com/visgl/deck.gl/issues/4582#issuecomment-627283569 : tileset-3d.js:481 A 3D tile failed to load: undefined Unexpected token F in JSON at position [...]
• pg2b3dm cesium sample-data of Delaware https://github.com/Geodan/pg2b3dm/tree/master/sample_data/delaware/cesium : WORKS!

The first two data are displayed in the correct place in CesiumJS. On the page with the examples at loaders.gl, all 3D tiles examples that do not have the data source via Cesium Ion do not work either.

Repro Steps

I used the deckgl 3d-tiles example ( https://github.com/visgl/deck.gl/tree/master/examples/website/3d-tiles ) and just replaced the tile3DLayer:

const tile3DLayer = new Tile3DLayer({ id: 'tile-3d-layer', data: './data/buildings/tileset.json', //data: './data/lod2_nrw/tileset.json', //data: './data/Manhattan/tileset.json', //data: './data/delaware-cesium-pg2b3dm/tileset.json', loader: Tiles3DLoader, loadOptions: { isTileset:true }, onTilesetLoad });

Environment

• Framework Version: deck.gl 8.4.6
• Browser Version: Chrome 88.0
• OS: Mac OS X 11.2.1

Hello!

1. To reproduce this issue I need tileset which you tried to load.
2. As for https://github.com/ikemarv/test-itowns-nrw/tree/master/apps/data/lod2_nrw tileset I uploaded it into Cesium ION app and it is really in Indian Ocean. And it looks really small and each mouse movement can eliminate tileset from camera view. Also I tried to view it in deck.gl tile3DLayer but viewer doesn't allow me to see it, maybe because tileset too small and has wrong positioning, elevation and orientation. And I converted it to I3S format as well and it helps me to find it out on the map -
3. As for Manhattan tileset it has deprecated tile structure which is not supported by loaders.gl.
4. https://github.com/Geodan/pg2b3dm/tree/master/sample_data/delaware/cesium As you said works. As for 3DTiles Tielsets on loaders.gl - thay are fixed.
