Compute and plot hexagonal grids
Project description
hexalattice
Generate and plot hexagonal lattices in 2D, with fine control over spacing between hexagons, arbitrary rotation of the grid around central tile, etc. The module computes and returns the center point for each fo the tiles in the lattice.
Installation
# Using pip
pip install hexalattice
# Using conda
conda install -c conda-forge hexalattice
Usage example
Create and plot 5x5 lattice of hexagons (as in first image):
from hexalattice.hexalattice import *
hex_centers, _ = create_hex_grid(nx=5,
ny=5,
do_plot=True)
plt.show() # import matplotlib.pyplot as plt
Get central points of the hexagons:
tile_centers_x = hex_centers[:, 0]
tile_centers_y = hex_centers[:, 1]
Plot one grid over the other, second with spacing around the hexagons:
_, h_ax = create_hex_grid(nx=5,
ny=7,
do_plot=True,
edge_color=(0.85, 0.85, 0.85))
create_hex_grid(nx=5,
ny=7,
do_plot=True,
edge_color=(0.25,0.25, 0.25),
h_ax=h_ax,
plotting_gap=0.3)
plt.show()
Create Moiré pattern from two circularly cropped hexagrids:
hex_grid1, h_ax = create_hex_grid(nx=50,
ny=50,
rotate_deg=0,
min_diam=1,
crop_circ=20,
do_plot=True)
create_hex_grid(nx=50,
ny=50,
min_diam=1,
rotate_deg=5,
crop_circ=20,
do_plot=True,
h_ax=h_ax)
