Numpy support

Using numpy to create mesh and get back its primitives

faces = np.ndarray(
    shape=(2, 3),
    dtype=np.int32,

            [2, 3, 0],
        ],
        dtype=np.int32,
    ),

# mrmesh uses float32 for vertex coordinates
# however, you could also use float64
verts = np.ndarray(
    shape=(4, 3),
    dtype=np.float32,
    buffer=np.array(
        [
            [0.0, 0.0, 0.0],

# some mesh manipulations
 
out_verts = mrmeshnumpy.getNumpyVerts(mesh)
out_faces = mrmeshnumpy.getNumpyFaces(mesh.topology)
