Using pythreejs in a Jupyter notebook

What is pythreejs?

pythreejs is a Jupyter-widgets-based notebook extension bridging Python with the threejs library for 3D animation in the web browser.

Using pythreejs in a Jupyter notebook with CoCalc

Here's what you can do e.g. to run these pythreejs examples:

1. Do the following in a CoCalc .term:

pip3 install --user pythreejs
jupyter nbextension install --user --py pythreejs
jupyter nbextension enable --user --py pythreejs
# it may be necessary to restart the jupyter server
smc-jupyter restart

2. From CoCalc Project Settings (wrench icon), start the Plain Jupyter Server (link at lower right of page).

3. Start a Jupyter notebook with the Python 3 (Ubuntu Linux) kernel you should be able to run pythreejs code.
