Loading 3D Tiles of France buildings takes long #2335

Open bertt opened 3 weeks ago

bertt commented 3 weeks ago

I'm trying to load a 3D Tileset of France buildings (https://storage.googleapis.com/ahp-research/maquette/ign/buildings/beta.3/1.0/tileset.json) in ITowns (latest commit main branch), but loading takes forever.

Demo: https://bertt.github.io/itowns_issues/france_buildings/issue/examples/index.html

In CesiumJS there is no problem loading this tileset see https://storage.googleapis.com/ahp-research/maquette/ign/buildings/beta.3/index.html

Hi, thanks for your issue and sorry for the late reply.

By looking at the network pane, we seem to load all tilesets before loading b3dms. I haven't find a quick fix yet.

We are currently deprecating our 3D tiles implementation and migrating to 3DTilesRendererJS (see this branch and #2225). This migration should land in the coming month. However it doesn't work on this branch either but with different symptoms :sweat_smile: We'll keep it in mind during this migration and try to fix it.
