DataSet.active_vectors_info

property DataSet.active_vectors_info: ActiveArrayInfoTuple

Return the active vector’s association and name.

Association refers to the data association (for example, point, cell, or field) of the active vectors.

Returns:

ActiveArrayInfo

The vectors info in an object with namedtuple semantics, with attributes association and name.

Notes

If the point and cell attributes both have active vectors and neither has been chosen at the dataset level, the point vectors are reported.

Examples

Download Python source code | Download Jupyter notebook

Create a mesh, compute the normals inplace, set the active vectors to the normals, and show that the active vectors are the 'Normals' array associated with points.

>>> import pyvista as pv
>>> mesh = pv.Sphere()
>>> _ = mesh.compute_normals(inplace=True)
>>> mesh.active_vectors_name = 'Normals'
>>> mesh.active_vectors_info
ActiveArrayInfoTuple(association=<FieldAssociation.POINT: 0>, name='Normals')
