Name filtering in the Plotly backend

The name_filter parameter accepts a regular-expression string and is available on Plotter.plot(), Plotter.plot_iter(), and Plotter.show(). Only MeshObjectPlot objects whose name matches the pattern are added to the figure; everything else is silently skipped.

class Part:
    """Minimal domain object with a name."""

    def __init__(self, name: str):
        self.name = name

Build a set of named parts

parts = [
    MeshObjectPlot(Part("Wheel_FL"), pv.Sphere(center=(-1,  1, 0), radius=0.3)),
    MeshObjectPlot(Part("Wheel_FR"), pv.Sphere(center=( 1,  1, 0), radius=0.3)),
    MeshObjectPlot(Part("Wheel_RL"), pv.Sphere(center=(-1, -1, 0), radius=0.3)),
    MeshObjectPlot(Part("Wheel_RR"), pv.Sphere(center=( 1, -1, 0), radius=0.3)),
    MeshObjectPlot(Part("Chassis"),  pv.Box(bounds=(-0.8, 0.8, -1.2, 1.2, 0, 0.4))),
]

Show with name_filter via show()

Pass name_filter directly to Plotter.show() together with the list of objects. The filter is applied while plotting, so only matching parts are added to the figure.

pl = Plotter(backend=PlotlyBackend())
pl.show(plottable_object=parts)

pl = Plotter(backend=PlotlyBackend())
pl.show(plottable_object=parts, name_filter="Wheel")
