Most basic example of instanced 3d model (using GLB)

3D Tiles
5

@bertt There are some different approaches for “placing something” - e.g. via glTF node transforms, via instancing transforms, or via tile transforms. But I’ll attach an example that contains

  • a tree.glb
  • a small CreateInstancedTrees.ts script, based on glTF-Transform, that reads that tree.glb and creates a treeInstanced.glb
  • the resulting treeInstanced.glb
  • a tileset JSON that was created by running createTilesetJson command of the 3d-tiles-tools on this file, and where I manually inserted a transform for the root tile to place that tile at a certain position on the globe

The result looks right …

Cesium Simple Trees Instanced

(Yes, the bounding box is wrong: The bounding box computation does not take the instancing into account, see Support for skinning and instancing in getBounds() · Issue #879 · donmccurdy/glTF-Transform · GitHub )

Which are the differences compared to I3DM that you refer to?
