LagrangeCurve

LagrangeCurve(*, cell_order: int = 3) → UnstructuredGrid

Create a pyvista.UnstructuredGrid containing a single Lagrange curve.

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

Parameters:

cell_orderint, default: 3

Order of interpolation to use.

Returns:

pyvista.UnstructuredGrid

UnstructuredGrid containing a single Lagrange curve.

Examples

Download Python source code | Download Jupyter notebook

Create and plot a single Lagrange curve.

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

List the grid’s cells.

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

List the grid’s points.

>>> grid.points
