Unable to plot point cloud only meshes

[GMNetto]

Hi,

I am following the example [scalar_fields] normals on windows with jupyter. I am able to see the plot for

anky.plot(mesh=True, backend="threejs")

However, for anky.plot, I get

Renderer(camera=PerspectiveCamera(aspect=1.6, fov=90.0, position=(0.015119519084692001, 2.41709041595459, 7.66…

HBox(children=(Label(value='Point size:'), FloatSlider(value=0.36411228179931643, max=3.641122817993164, step=…

I assume the plot is not being displayed, even though it was created.

Hi, seems the bug is because @jupyter-widgets/jupyterlab-manager extension is not installed.

Tested the following under jupyterlab running on remote notebook server, fixes the issue:
jupyter labextension install @jupyter-widgets/jupyterlab-manager

See jupyter-widgets/pythreejs#206

Thank you asbe!

Considering the link I also needed to do this:

jupyter lab clean
jupyter lab build
