PolyDataFilters.triangulate

PolyDataFilters.triangulate(

*,

pass_verts: bool = False,

pass_lines: bool = False,

inplace: bool = False,

progress_bar: bool = False,

)

Return an all triangle mesh.

More complex polygons will be broken down into triangles.

Parameters:

pass_vertsbool, default: False

Whether vertices cells are passed to the output PolyData.

Added in version 0.45.0.

pass_linesbool, default: False

Whether lines cells are passed to the output PolyData.

Added in version 0.45.0.

inplacebool, default: False

Whether to update the mesh in-place.

progress_barbool, default: False

Display a progress bar to indicate progress.

Returns:

pyvista.PolyData

Mesh containing only triangles.

Generate a mesh with quadrilateral faces.

>>> import pyvista as pv
>>> plane = pv.Plane()
>>> plane.point_data.clear()
>>> plane.plot(show_edges=True, line_width=5)
