pyvista.PolyDataFilters.plot_normals

PolyDataFilters.plot_normals(show_mesh=True, mag=1.0, flip=False, use_every=1, faces=False, color=None, **kwargs)

Plot the point normals of a mesh.

Parameters:

show_meshbool, default: true

Plot the mesh itself.

magfloat, default: 1.0

Size magnitude of the normal arrows.

flipbool, default: False

Flip the normal direction when True.

use_everyint, default: 1

Display every nth normal. By default every normal is displayed. Display every 10th normal by setting this parameter to 10.

facesbool, default: False

Plot face normals instead of the default point normals.

colorColorLike, optional

Color of the arrows. Defaults to pyvista.plotting.themes.Theme.edge_color.

**kwargsdict, optional

All additional keyword arguments will be passed to pyvista.Plotter.add_mesh().

Returns:

pyvista.CameraPosition

List of camera position, focal point, and view up. Returned when return_cpos is True.

Examples

Plot the point normals of a sphere.

>>> import pyvista as pv
>>> sphere = pv.Sphere(phi_resolution=10, theta_resolution=10)
>>> sphere.plot_normals(mag=0.1, show_edges=True)

Plot the face normals of a sphere.

>>> import pyvista as pv
>>> sphere = pv.Sphere(phi_resolution=10, theta_resolution=10)
>>> sphere.plot_normals(mag=0.1, faces=True, show_edges=True)
