From pypi:
pip install meshparty
We try to keep the pypi version up to date. To install the git version do:
git clone https://github.com/sdorkenw/MeshParty.git
cd MeshParty
pip install . --upgrade
Be aware that this installs a specific cloudvolume branch to allow integration of the new pychunkedgraph format graphene.
You might need to install assimp as well:
sudo apt-get install libassimp-dev
from mesh_party import trimesh_io
meshmeta = trimesh_io.MeshMeta()
mesh = meshmeta.mesh(path_to_mesh) # mesh gets cached
local_vertices = mesh.get_local_view(n_points, pc_align=True, method="kdtree")
Meshes can be downloaded in parallel using
trimesh_io.download_meshes(seg_ids, target_dir, cv_path)
where cv_path points to the cloudvolume bucket. For downloading proofread meshes one needs to
specify the mesh_endpoint of the chunkedgraph server:
trimesh_io.download_meshes(seg_ids, target_dir, cv_path, mesh_endpoint="https://...")
The mesh needs to be watertight In order to compute reliable information. To
test whether a mesh is watertight, run
mesh.is_watertight
To make a mesh watertight do
mesh.fix_mesh()
Since trimesh_io.Mesh() inherits from trimesh.Trimesh all trimesh functionality is available to mesh, e.g.:
mesh.volume
mesh.area
mesh.center_mass
