Lattice plane

The lattice plane is a plane that intersects the lattice. It is useful to visualize the lattice plane in the crystal structure.

Plane form miller indices

The lattice plane can be defined by the miller indices and distance from the origin or by selecting the atoms.

Here is an example of how to visualize lattice planes (111):

from ase.build import bulk
from weas_widget import WeasWidget
import numpy as np
atoms = bulk("Au", cubic=True)
viewer = WeasWidget()
viewer.from_ase(atoms)
viewer.avr.model_style = 1
viewer.camera.setting = {"direction": [0, -0.2, 1], "zoom": 0.8}
# color is defined by RGBA, where R is red, G is green, B is blue, and A is the transparency
viewer.avr.lp.add_plane_from_indices(name = "111",
                                        indices = [1, 1, 1],
                                        distance = 4,
                                        scale = 1.0,
                                        color = [0, 1, 1, 0.5])
viewer.avr.lp.build_plane()
viewer

Plane from selected atoms

One can also draw a plane from the selected atoms. Here is an example:

from ase.build import bulk
from weas_widget import WeasWidget
import numpy as np
atoms = bulk("Au", cubic=True)
viewer = WeasWidget()
viewer.from_ase(atoms)
viewer.avr.model_style = 1
viewer.avr.selected_atoms_indices=[0, 1, 2]
viewer.avr.lp.add_plane_from_selected_atoms(name = "plane1",
                                            color = [1, 0, 0, 0.5])
viewer.avr.lp.build_plane()
viewer
