Create Basic Geometric Objects

This is the “Hello, world!” of PyVista.

import pyvista as pv

This runs through several of the available geometric objects available in VTK which PyVista provides simple convenience methods for generating.

Let’s run through creating a few geometric objects!

cyl = pv.Cylinder()
arrow = pv.Arrow()
sphere = pv.Sphere()
plane = pv.Plane()
line = pv.Line()
box = pv.Box()
cone = pv.Cone()
poly = pv.Polygon()
disc = pv.Disc()

Now let’s plot them all in one window

pl = pv.Plotter(shape=(3, 3))
# Top row
pl.subplot(0, 0)
pl.add_mesh(cyl, color="tan", show_edges=True)
pl.subplot(0, 1)
pl.add_mesh(arrow, color="tan", show_edges=True)
pl.subplot(0, 2)
pl.add_mesh(sphere, color="tan", show_edges=True)
# Middle row
pl.subplot(1, 0)
pl.add_mesh(plane, color="tan", show_edges=True)
pl.subplot(1, 1)
pl.add_mesh(line, color="tan", line_width=3)
pl.subplot(1, 2)
pl.add_mesh(box, color="tan", show_edges=True)
# Bottom row
pl.subplot(2, 0)
pl.add_mesh(cone, color="tan", show_edges=True)
pl.subplot(2, 1)
pl.add_mesh(poly, color="tan", show_edges=True)
pl.subplot(2, 2)
pl.add_mesh(disc, color="tan", show_edges=True)
# Render all of them
pl.show()
# Export this plotter as an interactive scene to a HTML file.
# p.export_html("a_basic.html")
