pyvista.examples.cells.PolyVertex

PolyVertex() → UnstructuredGrid

Create a pyvista.UnstructuredGrid containing a single poly vertex.

This represents a set of 3D vertices as a single cell.

This cell corresponds to the pyvista.CellType.POLY_VERTEX cell type.

Returns:

pyvista.UnstructuredGrid

UnstructuredGrid containing a single poly vertex.

Examples

Create and plot a single poly vertex.

>>> from pyvista import examples
>>> grid = examples.cells.PolyVertex()
>>> examples.plot_cell(grid)

List the grid’s cells. This could be any number of points.

>>> grid.cells
array([6, 0, 1, 2, 3, 4, 5])

List the grid’s points.

>>> grid.points
pyvista_ndarray([[0. , 0. , 0. ],
                 [1. , 0. , 0. ],
                 [0. , 1. , 0. ],
                 [0. , 0. , 1. ],
                 [1. , 0. , 0.4],
                 [0. , 1. , 0.6]])

>>> grid.celltypes  # same as pyvista.CellType.POLY_VERTEX
array([2], dtype=uint8)
