3D Tiles Support Matrix

Capability	Support level	Scope	Diagnostics
Rust B3DM and tileset substrate	underdeveloped	Parser and renderer substrate exists, but public Python MapScene workflow is not complete.	python_public_3dtiles_incomplete.
Public Python scene integration	underdeveloped	MapScene accepts 3D Tiles intent for validation, diagnostics, support summaries, and review bundles; complete tile rendering remains diagnostic-bearing.	python_public_3dtiles_incomplete.
Unsupported tile features	unsupported	Unsupported B3DM/GLB features must be diagnosed before render.	Future tile-format diagnostics.
Large production tile hierarchies	non-goal	This feature does not claim Cesium runtime parity.	Documentation boundary.

3D Tiles support must distinguish Rust infrastructure from a public, renderable Python product workflow.
