Bumps trimesh from 4.11.2 to 4.11.5.

Release notes

Sourced from trimesh's releases.

Release 4.11.5

Release: Fix fill_holes with face attributes (#2518)

Trimesh.fill_holes was adding new faces but haphazardly managing the bookkeeping: it broke len(mesh.faces) == len(mesh.face_attributes[n]) if there were any holes filled.

  • add Trimesh.extend_faces which moves the bookkeeping of "preserve cached face normals to avoid recalculating, pad face colors, pad face attributes" to a generic mesh attribute in the same vein as mesh.update_faces.
  • refactor the tesselation of the holes in repair.fill_holes to use triangulate_quads which implemented the hole filling logic but better. Switch the winding search to a numpy indexing trick for new faces.
  • Have geometry.triangulate_quads use the preexisting util.triangle_fan_to_faces which uses numpy instead of a list comprehension and is heavily used and tested in the codebase.

Also:

  • try to test and fix #2516

Release 4.11.4

Release: Simple endian tests (#2512)

Even if we can't fully support other endian platforms, imports and exports should explicitly set endian-ness of outputs.

  • Adds a make test-arch which runs a subset of test on qemu/docker to catch simple problems on little-endian and 32bit platforms
  • Adds fix from #2506 which implemented Line.closed setter to auto-close polylines when passed.
  • Audit use of np.einsum/np.dot from good discussion in #2514. My conclusion was that numpy.dot is probably not the culprit and too core to avoid. As part of looking into this I benchmarked our other uses of np.einsum against simple numpy operations, it was on average ~2x slower. I also tried the `np.einsum(... optimize=True) as discussed in this interesting post but for the trimesh use cases of very simple expressions this was substantially slower in every case I measured.

Release 4.11.3

Release: Fix For Open Paths (#2507)

  • release #2505
  • switch while loop to bounded for loop in the traversals logic
