DataObjectFilters.cell_centers

DataObjectFilters.cell_centers#

DataObjectFilters.cell_centers( vertex: bool = True, pass_cell_data: bool = True, progress_bar: bool = False, )[source]#

Generate points at the center of the cells in this dataset.

These points can be used for placing glyphs or vectors.

Parameters:

vertexbool, default: True: Enable or disable the generation of vertex cells.
pass_cell_databool, default: True: If enabled, pass the input cell data through to the output.
progress_barbool, default: False: Display a progress bar to indicate progress.

Returns:

pyvista.PolyData: Polydata where the points are the cell centers of the original dataset.
