For anybody facing the same issue. A possible workaround could be to instantiate the rtree outside of trimesh and then store it into the mesh cache
def set_mesh_rtree(mesh: trimesh.Trimesh, tree_path: str) -> None:
if pathlib.Path(tree_path).exists():
raise FileExistsError(f"RTree already exists at specified location {tree_path}")
min_bounds = mesh.triangles.min(axis=1)
max_bounds = mesh.triangles.max(axis=1)
bounds = np.column_stack((min_bounds, max_bounds))
tree = rtree.index.Index(
tree_path,
zip(np.arange(len(mesh.faces)), bounds, [None] * len(mesh.faces)),
properties=rtree.index.Property(dimension=3),
)
mesh._cache.cache["triangles_tree"] = tree
from trimesh.
In the end it was a permission error, similar to Toblerity/rtree#185
The problem with the current version of rtree is that it doesn't write to the /tmp directory but to the current working directory. Hopefully this will be fixed in the next release of rtree - see libspatialindex/libspatialindex#220 (which is included in the latest release of libspatialindex).
