2.5D 3D tiles example is down #1877

Closed gchoqueux closed 2 years ago

gchoqueux commented 2 years ago

The 3D tiles isn't loaded in 2.5D 3D tiles example.

because the Liris server link responded with a status of 503

@ericboix and @agrignard have you an idea?

jailln commented 2 years ago

I don't know about the server but I can compute another tileset if this can help (similar to the previous one, but maybe on a larger zone and with textures). However where would we store it ? Is there a server for itowns demo data ?

@jailln, share your experience. With what software do you prepare tilesets?

jailln commented 2 years ago

I use py3dtilers which allows to transform citygml, obj, geojson and ifc files to 3d-tiles.

jailln commented 2 years ago

BTW the dataset seems to also be stored here

@jailln, maybe you can suggest. I'm trying to get 3D tiles to display from an obj file with a texture using py3dtilers tools. But as a result I get only one tile. I created a issue but i'm not sure if it's not on my side.

I'm not so familiar with the obj tiler of py3dtilers but I guess it depends on how your geometry is structured and how py3dtilers breaks your obj into several "features", which are then grouped by tiles. Anyway, maybe using this option can fix the number of features per tile. This discussion should be continued in the issue you created in py3dtilers, since it is not related to itowns, and I'm sure the py3dtilers team will give you a more comprehensive answer :)

@gchoqueux Concerning the broken link, this is our bad ! We moved away all our stable/shared tilesets from our project level server rict.liris.cnrs.fr to a more stable/permanent laboratory level server dataset-dl.liris.cnrs.fr. And we forgot to inform our data users. Although we made this move quite some time ago, the rict.liris.cnrs.fr virtual machine host was only (automatically) turned off this summer. Again, our bad, and sorry for not warning you guys.

Anyhow if you replace the original link http://rict.liris.cnrs.fr/DataStore/Lyon1er-2015/tileset.json with https://dataset-dl.liris.cnrs.fr/three-d-tiles-lyon-metropolis/2015/Lyon-1_2015/tileset.json the 3DTiles example should work again smoothly.

By the way, feel free to copy and host this tileset on some servers of yours in order to avoid this dependency and any further surprise (this data as an ETALAB license.

Although hopefully the lab level https://dataset-dl.liris.cnrs.fr/ server should have a much longer time span.
