PyPI Conda NumFOCUS Affiliated JOSS paper MIT License

PyVista is an open source, community-owned project, MIT licensed and NumFOCUS Affiliated.

CoDimensional PBC, founded by PyVista maintainers, is the project's commercial steward.

PyVista provides:

  • a NumPy-native API for 3D visualization and mesh analysis
  • dataset structures and filters for points, surfaces, and volumes
  • one plotting framework for notebooks, scripts, CI, and apps
  • a streamlined 3D interface for newcomers and graphics experts alike

Why PyVista

PyVista is the foundational Python library for 3D visualization and mesh analysis in scientific computing and engineering. It plays the same role for 3D data that pandas plays for tabular data and xarray plays for labeled n-dimensional arrays: NumPy-native datasets for point clouds, surfaces, and volumetric meshes; a filter API covering clipping, slicing, thresholding, smoothing, and dozens of other operations; and a unified plotting framework that runs interactively in Jupyter notebooks, headlessly in CI, and as embedded views inside larger web and desktop applications.

Built for production

PyVista is the reliable layer between user code and the underlying graphics stack. The library is image-regression tested on every commit across all Python versions still in their lifecycle and VTK releases, holds its public API stable through a deliberate deprecation lifecycle, and locks rendering behavior under visual regression baselines. The C++ toolkit underneath provides few of these assurances and doesn't share our enthusiasm for testing and reliability, which is why downstream science and engineering teams build on PyVista.

Built to extend

Your downstream code can build on PyVista through a small, lazily evaluated extension API. Third-party packages attach domain-specific filters and plotter components via registered accessors, with no subclassing, no monkey-patching, and no vendoring of upstream algorithms. See Extending PyVista for the contract.

Quickstart

PyVista runs on Python 3.10+:

pip install pyvista

Or via conda-forge:

conda install -c conda-forge pyvista

Try PyVista in your browser without installing anything, on MyBinder.

Command line interface

PyVista also installs a pyvista CLI for quick plotting, format conversion, and mesh validation, without writing any Python:

# Plot a mesh file in an interactive window
pyvista plot bunny.stl

# Convert a mesh file to another format
pyvista convert bunny.stl .vtp

# Validate a mesh's data, points, and cells
pyvista validate bunny.stl

See the CLI reference for the full set of commands and options.
