I don't think this actually works...

Seems to work.

import vtk
import numpy as np
import pyvista as pv
from pyvista import examples

mesh = pv.PolyData(np.random.random((100000, 3))*1000)

source = vtk.vtkSphereSource()
source.Update()
geom = source.GetOutput()

glyphed = mesh.glyph(geom=geom, progress_bar=True)

Cleaning: 100%|███████████████████████████████████████████████████████████[00:00<00:00]
Computing Glyphs: 100%|███████████████████████████████████████████████████[00:00<00:00]

Progress bar genuinely moves during the glyphing, though I had to make the "star field" quite dense to get it to actually need the progress bar.

Ah, thanks for testing this... I was having weird issues with the status bar going from 0 to 100 the other day without updating.

This “star field” is really cool btw

Had fun with that one. I wanted to make a quick video/gif following the camera angle. It would be super cool if we could "record" the camera angle and then replay that. We could accomplish this by starting a thread that records the camera position at various timesteps and then creates another video, or perhaps a "watch" feature that simply saves frames every timestep until the user closes out the plotter.

Perhaps record(filename, timestep)? That way you don't need an external recorder to save gifs.

Also could include a "press r to start recording" so the user could setup the camera angle.

Actually, this is something I'd really make use of...

Agreed. That would be incredibly useful and I can help implement this.
