Convert Stl into numpy array

Question

Is there way to convert the stl file content into a numpy array or a set of numpy arrays?

I know that I can always read stl as file and then assign variables, but I was wondering if there is an automated way!

Try the numpy-stl package.

After doing pip install numpy-stl:

import numpy
from stl import mesh

# Using an existing stl file:
your_mesh = mesh.Mesh.from_file('some_file.stl')

As I'm the author of the numpy-stl package, I've edited the answer to improve some example. This should be enough to help @marco further :) – Wolph Aug 13 '15 at 19:38

I recommend using trimesh for that. Here is an example script:

from trimesh import Trimesh
from trimesh import voxel
mesh = Trimesh()
mesh.vertices=vertices
mesh.faces=faces
array = voxel.VoxelMesh(mesh=mesh, pitch=1).matrix_solid
