PyVista is a general purpose 3D visualization library used for over 1400+ open source projects and many closed source projects for the visualization of everything from computer aided engineering and geophysics to volcanoes and digital artwork.
PyVista exposes a Pythonic API to the Visualization Toolkit (VTK) to provide tooling that is immediately usable without any prior knowledge of VTK and is being built as the 3D equivalent of Matplotlib, with plugins to Jupyter to enable visualization of 3D data using both server- and client-side rendering.
We will provide a hands-on tutorial accessible to anyone with internet access and a computer via many of PyVista's existing example Jupyter notebooks and new material through a comprehensive overview highlighting popular 3D visualization use cases.

Our tutorial will demonstrate PyVista's latest capabilities and bring a wide range of users to the forefront of 3D visualization in Python.
- Use PyVista to create 3D visualizations from a variety of datasets in common formats.
- Overview the classes and data structures of PyVista with real-world examples.
- Be familiar of the various filters and features of PyVista.
- Know which Python libraries are used and can be used by PyVista (meshio, trimesh etc).
We see this tutorial catering to anyone who wants to visualize data in any domain, and this ranges from basic Python users to advanced power users.

We will base the material for the tutorial on the examples in PyVista's online documentation. Transform 2021: Guide to PyVista Tutorial will also be used as material. The tutorial itself will be in the pyvista/pyvista-tutorial repository.
We see this tutorial catering to anyone who wants to visualize data in any domain, and this ranges from basic Python users to advanced power users.
In fact, our tutorial instructors and community members come from a diverse set of backgrounds.
- Basic knowledge of Python to get started. Be able to install Jupyter Lab on your machine and be up and running.
- Intermediate users will want to be familiar with NumPy and Matplotlib and perhaps other libraries that are compatible with PyVista, like trimesh or meshio.
- Advanced users should be familiar with the Visualization Toolkit (VTK) and general data science.
Something for everyone!
- Beginner
- Intermediate
- Advanced
