plot_normals#

PolyData.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, optional

Plot the mesh itself. Defaults to True.

magfloat, optional

Size magnitude of the normal arrows. Defaults to 1.0.

flipbool, optional

Flip the normal direction when True. Default False.

use_everyint, optional

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

facesbool, optional

Plot face normals instead of the default point normals.

colorcolor_like, optional

Color of the arrows. Defaults to pyvista.themes.DefaultTheme.edge_color.

**kwargsdict, optional

All additional keyword arguments will be passed to pyvista.BasePlotter.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)
