Collaboration opportunity?

[ibgreen]

Hi, very nice demo, thanks for sharing.

We are also developing a framework-independent 3d tile loader (part of our loaders.gl effort), you can see results developing at:

• https://loaders.gl/examples/3d-tiles
• https://loaders.gl/docs/specifications/category-3d-tiles
• https://loaders.gl/docs/api-reference/3d-tiles

A few remarks:

• We created loaders.gl to enable collaboration/interoperability with others developers, such as yourselves.
• As you have probably discovered, implementing the full 3d tiles standard is a big effort and as such, best shared.
• If collaboration sounds interesting, happy to connect.

Also:

• Could you clarify the licenses on your open source code, ideally by adding a LICENSE file to your repo? As it stands, it is not clear whether we can use/copy/fork your code
• One idea would be to port your mapbox/THREE.js sample to use the loaders.gl/3d-tiles loader and include as a demo on loaders.gl website (with attribution to yourselves of course!)
• If we can't use your implementation as a base due to licensing issues that is OK, we'd likely roll our own, but why reinvent the wheel when working with open source?

Hi @ibgreen, we weren't aware of the current efforts on 3d-tiles in loaders.gl, thanks so much for sharing! We will look into it.

In the meantime some answers:

• As far as we are aware there is a LICENSE file with a BSD-3 license in the repository.
• We are currently using the THREE.GLTFLoader(); to load the gltf models that are inside the 3D-tiles. I assume you are also using this function from THREEjs? Do you have an example implementation of that? I only saw a pointcloud implementation in your online examples.

@tomvantilburg Yes there it is! Don't know how I could have missed that. Awesome, thanks!

We don't, as I will explain below, however you can take the extracted GLB data from the Tile3DLoader and pass to THREE.GLTFLoader.

As context, loaders.gl is a suite of framework-independent loaders. The idea is that they can be used with any WebGL framework.

We currently only have an integration with our own https://deck.gl framework Tile3DLayer

But we'd love to be able to showcase a THREE.js integration as well, and your code would be a perfect baseline to build that example on.

If you are interested in using loaders.gl as a base we could collaborate on porting your THREE.js based example to loaders.gl.

We'd both benefit from sharing a common implementation of this quite complex standard, and we could share work on optimizing loading and traversal etc.

@tomvantilburg Quick update

• Initial port of your example to loaders.gl: 3d-tiles: Port Geodan THREE.js example visgl/loaders.gl#419
• Added your test tilesets to deck.gl-data: Add Geodan Rotterdam 3d-tiles visgl/deck.gl-data#14

The current port uses loaders.gl to parse the tiles, but does not yet use loaders.gl traversal algorithm, see the pull request for more information.
