Release: Scene Transform

[mikedh]

• fix that scene.scaled returned an invalid camera if it had been defined.
• add trimesh.scene.reconstruct_instances which uses trimesh.registration.procrustes and is actually very fast (10x faster on some simple data than scene.duplicate_nodes) and gives great results on baked scenes.
  • add a bunch of type hints to trimesh.registration
• add a Scene.simplify_quadric_decimation which runs mesh.simplify_quadric_decimation for every mesh geometry in the scene.
• release Fix typing bug in merge_vertices function #2281
• release Docs/documentation fixes #2279
  • Also add a trimesh.convex.QhullOptions dataclass with a blurb for every boolean flag option in 8b2d46e, so you can construct this string with something like QhullOptions(QbB=True) and read the docstrings as you're doing it.
• release Update gmsh.py #2280
• set the VIRTUAL_ENV variable in the Dockerfile which lets upstream potentially use uv.
• Attempt to add a body to the Github releases in CI.
• Deprecations for April 2025
  • Scene.dump(concatenate=True) which should be replaced with Scene.to_geometry() or Scene.to_mesh(), as otherwise the return types are inconsistent. This also lays some groundwork for [WIP] Refactor Load Types #2241 as trimesh.load_mesh will be a thin wrapper around trimesh.load_scene(...).to_mesh()
  • Scene.deduplicated is removed because it's one line and also mildly pointless, you can get the same effect with Scene(list({g.identifier_hash: g for g in self.geometry.values()}.values()))
