pyvista.DataSet.get_cell#

DataSet.get_cell(index: int) → Cell[source]#

Return a pyvista.Cell object.

Parameters:

indexint: Cell ID.

Returns:

pyvista.Cell: The i-th pyvista.Cell.

Notes

Cells returned from this method are deep copies of the original cells. Changing properties (for example, points) will not affect the dataset they originated from.

Examples

Get the 0-th cell.

>>> from pyvista import examples
>>> mesh = examples.load_airplane()
>>> cell = mesh.get_cell(0)
>>> cell
Cell ...

Get the point ids of the first cell

>>> cell.point_ids
[0, 1, 2]

Get the point coordinates of the first cell

>>> cell.points
array([[897.0,  48.8,  82.3],
       [906.6,  48.8,  80.7],
       [907.5,  55.5,  83.7]])

For the first cell, get the points associated with the first edge

>>> cell.edges[0].point_ids
[0, 1]

For a Tetrahedron, get the point ids of the last face

>>> mesh = examples.cells.Tetrahedron()
>>> cell = mesh.get_cell(0)
>>> cell.faces[-1].point_ids
[0, 2, 1]
