================================ volume2mesh (and mesh to volume)

Voxelize meshes to volumes. Save meshes from volumes.

This package provides to functions volume2mesh and mesh2volume to convert between NumPy volume arrays and meshes:

.. code:: python

file = '/tmp/my_mesh_file.obj' volume = np.zeros((100, 120, 131), np.float32) volume[20:40, 30:40, 40:50] = 1

volume2mesh(file, volume, threshold=0.5, adaptivity=0., spacing=[1., 1., 1.], origin=[0., 0., 0.], binary_file=True, only_write_biggest_components=False, max_component_count=1)

And to voxelize meshes:

.. code:: python

bunny_file = '~/my_bunnyfile.stl' volume = volume2mesh.mesh2volume(bunny_file, scaling=1.)

Installation

You need to have OpenMesh <https://www.openmesh.org/>_ linkable via -lOpenMeshCore and OpenVDB <openvdb.org>_ installed.

On on Ubuntu, you can do this by these commands (see our Travis Script <https://github.com/theHamsta/volume2mesh/blob/master/.travis.yml>_):

.. code:: bash

Install OpenVDB

sudo apt-get install -y libopenvdb-dev build-essential libboost-all-dev libtbb-dev

Install OpenMesh

git clone https://www.graphics.rwth-aachen.de:9000/OpenMesh/OpenMesh.git || echo "hi" cd OpenMesh git pull mkdir -p release cd release && cmake -DCMAKE_BUILD_TYPE=Release .. && cmake --build . -- -j4 sudo make install

Install this package

pip3 install volume2mesh --user

Or if you cloned this repo

pip3 install -e . --user
