BezierTriangle

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

Create a pyvista.UnstructuredGrid containing a single Bezier triangle.

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

Parameters:

cell_orderint, default: 3

Order of interpolation to use.

Returns:

pyvista.UnstructuredGrid

UnstructuredGrid containing a single Bezier triangle.
