[QGIS-Developer] Exact specification of the 3D Tiles support in QGIS?

[Martin Dobias]

Hi Hannes

Would it alright if I added this information to
> https://docs.qgis.org/latest/en/docs/user_manual/working_with_3d_tiles/3d_tiles.html#what-are-3d-tiles
> ? Marketing-wise it would be a bit negative ("partial XX support" sounds
> worse than plain "3D Tiles support"), but I think for users it would be
> super helpful.

That would be indeed very useful - thanks for volunteering to add that :)

Correct - both text and binary encodings are supported. Essentially it is
support of 3DTILES_content_gltf extension.

(Note: EXT_mesh_gpu_instancing extension is not supported yet - that's kind
of equivalent of "i3dm" encoding into gltf)


Yeah it seems like there is a lot of "flavours" of 3D Tiles in addition to

Yeah there are some extensions, which eventually got adopted into 3D Tiles
1.1.

Cool - will be interesting to see what you can achieve!
By the way, Cesium ion has quite generous free tier and can generate 3D
tiles from lots of formats...

Cheers
