Plot a simple sphere using PyVista#
This code plots a simple sphere using PyVista.
import pyvista as pv
pv.set_jupyter_backend("html")
sphere = pv.Sphere()
sphere.plot()
Plot a simple sphere using PyVista with a plotter
plotter = pv.Plotter(notebook=True)
plotter.add_mesh(sphere, color="white", show_edges=True)
plotter.title = "3D Sphere Visualization"
plotter.show()
