3D Tiles 1.1 - Implicit Tiling - Octree support? #2423

Closed bertt closed 1 month ago

bertt commented 1 month ago

I'm trying to get the Cesium demo with Implicit Tiling and Octree (https://github.com/CesiumGS/3d-tiles-samples/tree/main/1.1/SparseImplicitOctree) working in ITowns, but I'm getting errors.

Demo in Cesium (works): https://bertt.github.io/itowns_issues/octree/index.html

Demo in ITowns (does not work): https://www.itowns-project.org/itowns/examples/3dtiles_loader.html?tileset=https://bertt.github.io/itowns_issues/octree/tileset.json

Error "Failed to load tile at url "content/content_1__0_0_undefined.glb"."

Is Implicit Tiling and Octree supported?

Thank you for the issue. Octree is not yet supported for implicitTiling. There is a list of what's left to implement for this feature: https://github.com/NASA-AMMOS/3DTilesRendererJS/issues/608#issuecomment-2283364305 I don't think that a MR is ongoing concerning Octree implementation.If you feel like it, don't hesitate to try to add it in the 3DTilesRendererJS lib, it could be a nice addition :D

ok thanks, good to see it as first item on the list :-)
