DataSetFilters.integrate_data#

DataSetFilters.integrate_data(*, progress_bar: bool = False) → UnstructuredGrid[source]#

Integrate point and cell data.

Area or volume is also provided in point data.

This filter uses vtkIntegrateAttributes.

Parameters:
progress_barbool, default: False

Display a progress bar to indicate progress.

Returns:
pyvista.UnstructuredGrid

Mesh with 1 point and 1 vertex cell with integrated data in point and cell data.

Integrate data on a sphere mesh.

>>> import pyvista as pv
>>> import numpy as np
>>> sphere = pv.Sphere(theta_resolution=100, phi_resolution=100)
>>> sphere.point_data['data'] = 2 * np.ones(sphere.n_points)
>>> integrated = sphere.integrate_data()

There is only 1 point and cell, so access the only value.

>>> integrated['Area'][0]
np.float64(3.14)
>>> integrated['data'][0]
np.float64(6.28)
