Release 4.7.3

Release: Parent Loggers + Numpy Dtype Hotfix (#2430)

In trimesh.util.attach_to_log(only_parent=True) if there exist loggers
for project, project.other, project.other2, this will only attach
to project. By default it is off so it shouldn't change upstream
behavior.

We should also probably be doing instead of from .util import log,
log = getLogger(__name__) everywhere.

Release Notes

• Adds the parent logging behavior
• latest numpy dtypes now show up as |u8 instead of <u8, which we
  need to strip for the GLTF lookup table.
• slightly janky fix for #2419 which at least preserves the vertex
  colors, but should probably be refactored to always store them in
  vertex_attributes. That would be a large change and I'm not sure it's
  possible to do without breaking the API.
• release #2432

Release 4.7.1

Release: Scene Type Hints (#2427)

• adds a type hint to scene.show with a Literal to fix #2426
• For some reason a reexport of typing.Literal from trimesh.typed
  does not work with ruff.

Release 4.7.0

Release: Remove GMSH (#2422)

Trimesh's interface to gmsh has been scheduled for removal and has been
printing this warning for more than a year:

trimesh.interfaces.gmsh is deprecated and will be removed January
2025! There are many gmsh options on PyPi: scikit-gmsh gmsh
pygmsh gmsh-sdk, users should pick one of those and use it directly.
If STEP loading is the only thing needed you may want pip install cascadio which uses OpenCASCADE more directly and will immediately
enable STEP as a loadable format in trimesh.

Changes in this release:

• remove trimesh.interfaces.gmsh
• release #2423
• release #2424
• fix pycollada dependency on Python 3.8

Release 4.6.13

Release: Layer Filter For Path.copy (#2418)

• add and test path.copy(layers={1, 2}) to only copy particular
  layers.
• add the note about signed angles discussed in #2416
• add a trimesh.primitives.Extrusion(..., mid_plane: bool) option as a
  helper to produce extrusions that are centered at the origin.
• convert test_extrude and test_primitives to pytest style, and
  remove the outdated test skip if triangle isn't installed.
• fix and test units on 3MF imports, which were being stomped by the
  metadata = None keyword argument.
• remove unused trimesh.exchange.gltf._mesh_to_materials function.
• release #2420

Release 4.6.12

Release: Docstrings + IMC (#2417)

• fix minimum Python version in readme
• release #2416
• release #2415

Release 4.6.11

Release: Don't Copy Embree Scenes (#2411)

• try to fix #2410
• release #2409 which fixes #2408
• release #2404
• deprecate OpenCTM as it is abandoned, fully superseded by Google's
  Draco, and was causing maintenance burden for upstream packaging teams.

Release 4.6.10

Release: More SVG Fixes (#2406)

• fix #2405 and test
• preserve OBJ material names through a roundtrip mentioned in #2349

Release 4.6.9

Release: SVG Fixes (#2397)

• release #2395
• release #2401 which tests and fixes #2253
• add test and fix #2379
• test and fix #2402
• test and fix #2403
• both SVG cases are now tested by converting the SVG transform tree
  into a single fully evaluated path string in Inkscape and then
  confirming the set-of-AABB matches with our evaluation.
• add identifier_hash to the abstract base class parent.Geometry
• adds trimesh.inertia.points_inertia to calculate the tensor of an
  array of point masses to use as a simple identifier for the PointCloud.
  points_inertia is also useful for approximating a moment of inertia
  from samples, which we test by sampling the volume of a random box.
• adds a test that caught Path identifiers being only 2 values from an
  incorrect axis on a sum.
