ImageData.active_normals

property ImageData.active_normals: pyvista_ndarray | None

Return the active normals as an array.

Returns:

pyvista_ndarray

Active normals of this dataset.

Notes

If both point and cell normals exist, this returns point normals by default.

Examples

Download Python source code | Download Jupyter notebook

Compute normals on an example sphere mesh and return the active normals for the dataset. Show that this is the same size as the number of points.

>>> import pyvista as pv
>>> mesh = pv.Sphere()
>>> mesh = mesh.compute_normals()
>>> normals = mesh.active_normals
>>> normals.shape
(842, 3)
>>> mesh.n_points
842
