pyvista.DataSet.point_cell_ids

DataSet.point_cell_ids(ind: int) → List[int]

ind番目の点を使用するセルIDを返します．

vtkDataSet の GetPointCells をインプリメントします．

パラメータ:

indint

ポイントIDです．

戻り値:

List[int]

ind番目の点を使用したセルIDのリスト．

例

0番目の点を用いてセルIDを返します．

>>> import pyvista as pv
>>> mesh = pv.Sphere(theta_resolution=10)
>>> mesh.point_cell_ids(0)
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

それらをプロットします．

>>> pl = pv.Plotter()
>>> _ = pl.add_mesh(mesh, show_edges=True)
>>>
>>> # Label the 0-th point
>>> _ = pl.add_point_labels(
...     mesh.points[0], ["0"], text_color="blue", font_size=20
... )
>>>
>>> # Get the cells ids using the 0-th point
>>> ids = mesh.point_cell_ids(0)
>>> cells = mesh.extract_cells(ids)
>>> _ = pl.add_mesh(cells, color="red", show_edges=True)
>>> centers = cells.cell_centers().points
>>> _ = pl.add_point_labels(
...     centers,
...     labels=[f"{i}" for i in ids],
...     text_color="white",
...     font_size=20,
...     shape=None,
...     show_points=False,
... )
>>>
>>> # Plot the other cells
>>> others = mesh.extract_cells(
...     [i for i in range(mesh.n_cells) if i not in ids]
... )
>>> _ = pl.add_mesh(others, show_edges=True)
>>>
>>> pl.camera_position = "yx"
>>> pl.camera.zoom(7.0)
>>> pl.show()
