This page provides a curated list of useful Python extensions for OVITO, e.g., new modifiers, file readers, and viewport layers. These extensions have been developed and contributed by independent members of the OVITO user community. They are hosted in external code repositories, which are maintained by their respective authors.

Please see each extension’s documentation or the OVITO manual for installation instructions. Most extensions can be used with OVITO Pro and the standalone OVITO Python Module (version 3.9 or later).

How to submit your extension

If you would like your own extension to be added to this list by the OVITO team, please write to social@ovito.org. Alternatively, you can open an issue or submit a pull request to the GitHub repository.

Modifiers

Atomistic Reverse Monte-Carlo

Generate bulk crystal structures with target Warren-Cowley parameters.

https://github.com/killiansheriff/AtomisticReverseMonteCarlo

Calculate bond angles at particle

Outputs the angles between all pairwise combinations of bonds at one particle.

Denoise particle positions

Wrapper for the “Score-based denoising for atomic structure identification” method presented in this arXiv preprint and implemented here.

Display Lammps log

Display the Lammps log file alongside your structure data in OVITO Pro.

Generate random solution

Randomly assigns types to particles to create a solution with given composition.

Ring Finder

Finds shortest rings formed by bonds in the system.

Warren-Cowley short-range order parameters

Calculates the Warren-Cowley short-range order parameters.

File Readers

Pyiron file reader

Reads HDF5 data containers written by pyiron.

Viewport Layers

Data table plot

Include plots generated from data tables from your pipeline in your image or animation rendered with OVITO Pro.

https://github.com/ovito-org/DataTablePlotOverlay.git

Measure Distances And Angles

Measure both distances and angles between particles and display them as a layer in the viewport.
