Pick a horizon along a 2.5D cross section of GPR imagery.
import pyvista as pv
from pyvista import examples
path, _ = examples.downloads._download_file("gpr-line.vtu")
mesh = pv.read(path)p = pv.Plotter()
p.add_mesh(mesh)
p.enable_horizon_picking()
p.camera_position = [

help(p.enable_horizon_picking)Help on method enable_horizon_picking in module pyvista.plotting.picking:
enable_horizon_picking(callback=None, normal=(0, 0, 1), width=None, show_message=True, font_size=18, color='pink', point_size=10, line_width=5, show_path=True, opacity=0.75, show_horizon=True, **kwargs) method of pyvista.plotting.plotting.Plotter instance
Enable horizon picking.
Helper for the ``enable_path_picking`` method to also show a
ribbon surface along the picked path. Ribbon is saved under
``.picked_horizon``.
Parameters
----------
callback : callable, optional
When given, calls this function after a pick is made. The
entire picked path is passed as the only parameter to this
function.
normal : tuple(float), optional
The normal to the horizon surface's projection plane.
width : float, optional
The width of the horizon surface. Default behaviour will
dynamically change the surface width depending on its
length.
show_message : bool or str, optional
Show the message about how to use the horizon picking
tool. If this is a string, that will be the message shown.
font_size : int, optional
Sets the font size of the message.
color : color_like, optional
The color of the horizon surface if shown.
point_size : int, optional
Size of picked points if ``show_horizon`` is
``True``. Default 10.
line_width : float, optional
Thickness of path representation if ``show_horizon`` is
``True``. Default 5.
show_path : bool, optional
Show the picked path that the horizon is built from
interactively.
opacity : float, optional
The opacity of the horizon surface if shown.
show_horizon : bool, optional
Show the picked horizon surface interactively.
**kwargs : dict, optional
All remaining keyword arguments are used to control how
the picked path is interactively displayed.
