It would be interesting to render the images from the POV of a player in the world onto a large movie screen in game. Then other players could join in, go to the cinema and watch the live stream. Might be fun for game lobbies.
rendering-minecraft w/ mcpi might do offline / batch rendering? https://pypi.org/project/rendering-minecraft/
Jupyter-cadquery might be worth a look: https://github.com/bernhard-42/jupyter-cadquery :
> View CadQuery objects in JupyterLab or in a standalone viewer for any IDE [w/ pythreejs]
If there's a JS port or WASM build of Minecraft, Minecraft could be rendered in a headless browser?
