Geometric Objects#
The “Hello, world!” of VTK. Uses objects from Geometry.
from __future__ import annotations
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
p = pv.Plotter(shape=(3, 3))
# Top row
p.subplot(0, 0)
p.add_mesh(cyl, color='lightblue', show_edges=True)
p.subplot(0, 1)
p.add_mesh(arrow, color='lightblue', show_edges=True)
p.subplot(0, 2)
p.add_mesh(sphere, color='lightblue', show_edges=True)
# Middle row
p.subplot(1, 0)
p.add_mesh(plane, color='lightblue', show_edges=True)
p.subplot(1, 1)
p.add_mesh(line, color='lightblue', line_width=3)
p.subplot(1, 2)
p.add_mesh(box, color='lightblue', show_edges=True)
# Bottom row
p.subplot(2, 0)
p.add_mesh(cone, color='lightblue', show_edges=True)
p.subplot(2, 1)
p.add_mesh(poly, color='lightblue', show_edges=True)
p.subplot(2, 2)
p.add_mesh(disc, color='lightblue', show_edges=True)
# Render all of them
p.show()
