Use a PyVista Qt backend

PyVista Qt is a package that extends the PyVista functionality through the usage of Qt. Qt applications operate in a separate thread than VTK, you can simultaneously have an active VTK plot and a non-blocking Python session.

This example shows how to use the PyVista Qt backend to create a plotter

import pyvista as pv

from ansys.tools.visualization_interface import Plotter
from ansys.tools.visualization_interface.backends.pyvista import PyVistaBackend

Open a pyvistaqt window

cube = pv.Cube()
pv_backend = PyVistaBackend(use_qt=True, show_qt=True)
pl = Plotter(backend=pv_backend)
pl.plot(cube)
pl.backend.enable_widgets()
pv_backend.scene.show()

Parallel VTK window

sphere = pv.Sphere()

pl_parallel = Plotter()
pl_parallel.plot(sphere)
pl_parallel.show()

Static Scene

Interactive Scene

Close the pyvistaqt window

pv_backend.close()

Integrate the plotter in a Qt application

pv_backend = PyVistaBackend(use_qt=True, show_qt=False)
pv_backend.enable_widgets()

# You can use this plotter in a Qt application
pl = pv_backend.scene
