My Question

Hi all, I'd like to use the JVisualizer for Jupyter Notebooks. The documentation at https://www.open3d.org/docs/latest/tutorial/Basic/jupyter.html says:

Since version 0.4.0, we added experimental support for Jupyter visualization with WebGL. If Open3D is installed from PyPI or Conda, Jupyter support is enabled by default.

and I've installed the latest version, 0.18,0 via pip as advised by the widget on https://www.open3d.org/.

Indeed this function isn't importable:

from open3d.j_visualizer import JVisualizer

giving:

ModuleNotFoundError: No module named 'open3d.j_visualizer'

A previous issue says this works:

from open3d.j_visualizer import JVisualizer

but that's the same ModuleNotFoundError. That same issue links to a notebook in the open3d repo: https://github.com/isl-org/Open3D/blob/main/docs/jupyter/visualization/jupyter_visualization.ipynb

from open3d.web_visualizer import draw

but trying that gives a runtime error, suggesting the jupyter part wasn't isntalled with pip:

RuntimeError: Open3D WebVisualizer Jupyter extension is not available. To use WebVisualizer, build Open3D with -DBUILD_JUPYTER_EXTENSION=ON.

does this require a manual build?
