VTK，PyVista，Trameの使用

この例では，VTK，PyVista，Trameを一緒に使用する方法を示し，3つのライブラリがどのようにお互いを補い合うかを示します．

import pyvista as pv
from pyvista.trame.ui import plotter_ui
from trame.app import get_server
from trame.ui.vuetify3 import SinglePageLayout
from trame.widgets import vuetify3
from vtkmodules.vtkFiltersSources import vtkConeSource

pv.OFF_SCREEN = True

server = get_server()
state, ctrl = server.state, server.controller

source = vtkConeSource()

pl = pv.Plotter()
pl.add_mesh(source, color="seagreen")


@state.change("resolution")
def update_contour(resolution, **kwargs) -> None:
    source.SetResolution(int(resolution))
    ctrl.view_update()


with SinglePageLayout(server) as layout:
    with layout.toolbar:
        vuetify3.VSpacer()
        vuetify3.VSlider(
            v_model=("resolution", 15),
            min=5,
            max=30,
            hide_details=True,
            density="compact",
            style="max-width: 300px",
            change=ctrl.view_update,
        )
        vuetify3.VProgressLinear(
            indeterminate=True,
            absolute=True,
            bottom=True,
            active=("trame__busy",),
        )

    with (
        layout.content,
        vuetify3.VContainer(
            fluid=True,
            classes="pa-0 fill-height",
        ),
    ):
        # Use PyVista UI template for Plotters
        view = plotter_ui(pl)
        ctrl.view_update = view.update

# Show UI
await layout.ready
