gradio-pyvistaplotter: Interactive 3D viewer for gradio applications

A Gradio custom component that embeds an interactive PyVista plotter in any Gradio app.

Installation

pip install gradio-pyvistaplotter

Quick Start

The following minimal example renders an interactive 3D sphere:

import pyvista as pv
import gradio as gr
from gradio_pyvistaplotter import PyvistaPlotter

plotter = pv.Plotter()
plotter.add_mesh(pv.Sphere(), show_edges=True, color="gold")

with gr.Blocks() as demo:
    gr.Markdown("Gradio app with a PyVista plotter")
    viewer = PyvistaPlotter(value=plotter)

demo.launch()

A more complete example with a mesh loader is available in gradio_pyvistaplotter/demo/app.py.

Known Issues

(Linux only) Ctrl+C does not stop the application

When using PyvistaPlotter with the standard gr.Blocks.launch() method from gradio, the application cannot be interrupted from the terminal via Ctrl+C. As a workaround, this package provides a custom launch() function that wraps gr.Blocks.launch() with proper signal handling:

import pyvista as pv
import gradio as gr
from gradio_pyvistaplotter import PyvistaPlotter, launch

plotter = pv.Plotter()
plotter.add_mesh(pv.Sphere(), show_edges=True, color="gold")

with gr.Blocks() as demo:
    gr.Markdown("Gradio app with a PyVista plotter")
    viewer = PyvistaPlotter(value=plotter)

launch(demo)  # custom launch with proper signal handling

Issues / TODO

• Currently, two files are written to the tmp directory on each render: static_viewer.html and scene_<id>.vtksz. Investigate whether the HTML can be generated and passed as an in-memory string instead of a file on disk.
• static_viewer.html is currently bundled with this package — should it be imported directly from trame instead?
