pyvista-js: PyVista-like 3D visualization for stlite / vtk.js

[tkoyama010]

Hi everyone!

I'm excited to share pyvista-js, a new library that brings the intuitive API of PyVista to the browser via vtk.js.

It is specifically designed to work seamlessly in WASM environments like stlite and JupyterLite, making complex 3D visualization accessible without a dedicated backend server.

Why pyvista-js?
While PyVista is powerful, rendering interactive 3D graphics in a purely client-side environment (like stlite) has been a challenge. pyvista-js bridges this gap by providing a familiar Pythonic API that feels like PyVista but runs entirely on vtk.js.

Try it with JupyterLite	Try it with Stlite

Hey @tkoyama010 this is amazing. Thank you for sharing it!

The sample source code is here https://github.com/tkoyama010/pyvista-js/tree/main/stlite ?

I also ported it into Stlite Sharing as below, and it works!

Thanks! I am starting using it (tkoyama010/pyvista-js#386).

Thanks!
Looks like it would be better if your source code can be dynamically converted into Stlite Sharing's URL in the CI pipeline, and it's a duty on my side to provide a library to realize it. Plz stay tuned...
