QuadraticPolygon

QuadraticPolygon() → UnstructuredGrid

Create a pyvista.UnstructuredGrid containing a single quadratic polygon.

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

Returns:

pyvista.UnstructuredGrid

UnstructuredGrid containing a single quadratic polygon.

Examples

List the grid’s cells.

>>> grid.cells
array([8, 0, 1, 2, 3, 4, 5, 6, 7])

List the grid’s points.

>>> grid.points
