# Examples from pyvista.Icosphere
# ===============================

# Create the icosphere and plot it with edges.
import pyvista as pv
icosphere = pv.Icosphere()
icosphere.plot(show_edges=True)

# Show how this icosphere was created.
import numpy as np
icosahedron = pv.Icosahedron()
icosahedron.clear_data()  # remove extra scalars
icosahedron_sub = icosahedron.subdivide(nsub=3)
pl = pv.Plotter(shape=(1, 3))
_ = pl.add_mesh(icosahedron, show_edges=True)
pl.subplot(0, 1)
_ = pl.add_mesh(icosahedron_sub, show_edges=True)
pl.subplot(0, 2)
_ = pl.add_mesh(icosphere, show_edges=True)
pl.show()

# Show how the triangles are not uniform in area. This is because the
# ones farther from the edges from the original triangles have farther
# to travel to the sphere.
icosphere = pv.Icosphere(nsub=4)
icosphere.compute_cell_sizes().plot(scalars='Area')
