volume2mesh 0.2.2

Add a short description here!

volume2mesh

Voxelize meshes to volumes. Save meshes from volumes.

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

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:

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

Installation

You need to have OpenMesh linkable via -lOpenMeshCore and OpenVDB installed.

On on Ubuntu, you can do this these commands (see our Travis Script):

# 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
