3D visualization and mesh analysis for science and engineering

PyVista is an open source, community-owned project, MIT licensed and
 <a href="https://numfocus.org/sponsored-projects/affiliated-projects">NumFOCUS Affiliated</a>.

<a href="https://codimensional.com">CoDimensional PBC</a>,
 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](https://vtk.org) 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](https://docs.pyvista.org/extras/extending_pyvista) for
the contract.

## Quickstart

PyVista runs on Python 3.10+:

```bash
pip install pyvista
```

Or via conda-forge:

```bash
conda install -c conda-forge pyvista
```

Try PyVista in your browser without installing anything, on
[MyBinder](https://mybinder.org/v2/gh/pyvista/pyvista-examples/master).

## Command line interface

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

```bash
# 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](https://docs.pyvista.org/api/cli) for the full
set of commands and options.
