polylabel-pyo3
polylabel-pyo3 lets you calculate the pole of inaccessibility in Python. It's a pyo3 wrapper of polylabel-rs.
Install
pip install polylabel-pyo3
Use
from polylabel_pyo3 import polylabel_ext, polylabel_ext_np
# define an open L-shape
L = [(0,0),(1,0),(1,1),(2,1),(2,2),(0,2)]
polylabel_ext(L, 1.0)
# (0.5, 0.5)
# A version for numpy.ndarray only is slightly faster
import numpy as np
polylabel_ext_np(np.array(L, dtype=np.float), 1.0)
# (0.5, 0.5)
# Note that the optional polylabel center for an L-shape
# is in between its mean of exterior vertices and origin
np.mean(L, axis=0)
# array([1., 1.])
GUI Example
pip install -r examples/requirements.txt
python examples/polylabel_gui.py
Drag your shape with the mouse and observe a momentum based center in grey and polylabel center in green:
