Clearing a Mesh or the Entire Plot

This example demonstrates how to remove elements from a scene using clear().

from __future__ import annotations

import pyvista as pv

pl = pv.Plotter()
actor = pl.add_mesh(pv.Sphere())
pl.remove_actor(actor)
pl.show()

Static Scene

Interactive Scene

Clearing the entire plotting window:

pl = pv.Plotter()
pl.add_mesh(pv.Sphere())
pl.add_mesh(pv.Plane())
pl.clear()  # clears all actors
pl.show()

Static Scene

Interactive Scene

Or you can give any actor a name when adding it and if an actor is added with that same name at a later time, it will replace the previous actor:

pl = pv.Plotter()
pl.add_mesh(pv.Sphere(), name='mymesh')
pl.add_mesh(pv.Plane(), name='mymesh')
# Only the Plane is shown.
pl.show()
