Geometric Objects

The “Hello, world!” of VTK

import pyvista as pv

This runs through several of the available geomoetric objects available in VTK which PyVista provides simple conveinance 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

p = pv.Plotter(shape=(3, 3))
# Top row
p.subplot(0, 0)
p.add_mesh(cyl, color="tan", show_edges=True)
p.subplot(0, 1)
p.add_mesh(arrow, color="tan", show_edges=True)
p.subplot(0, 2)
p.add_mesh(sphere, color="tan", show_edges=True)
# Middle row
p.subplot(1, 0)
p.add_mesh(plane, color="tan", show_edges=True)
p.subplot(1, 1)
p.add_mesh(line, color="tan", line_width=3)
p.subplot(1, 2)
p.add_mesh(box, color="tan", show_edges=True)
# Bottom row
p.subplot(2, 0)
p.add_mesh(cone, color="tan", show_edges=True)
p.subplot(2, 1)
p.add_mesh(poly, color="tan", show_edges=True)
p.subplot(2, 2)
p.add_mesh(disc, color="tan", show_edges=True)
# Render all of them
p.show()
