pyvista.examples.cells.BezierQuadrilateral#

BezierQuadrilateral(*, cell_order: int = 3) → UnstructuredGrid[source]#

Create a pyvista.UnstructuredGrid containing a single Bezier quadrilateral.

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

Parameters:
cell_orderint, default: 3

Order of interpolation to use.

Returns:
pyvista.UnstructuredGrid

UnstructuredGrid containing a single Bezier quadrilateral.

Examples

Create and plot a single Bezier quadrilateral.

>>> from pyvista import examples
>>> grid = examples.cells.BezierQuadrilateral()
>>> examples.plot_cell(grid, cpos='xy')
../../../_images/pyvista-examples-cells-BezierQuadrilateral-3e4e74c2e87e8619_00_00.png

List the grid’s cells.
