OVITO

About

OVITO (Open Visualization Tool) is a scientific data visualization and analysis solution for particle-based simulations, available for MacOS along with Windows, Linux, and Conda. It is designed for particle simulations of any scale, from ab initio models to large-scale models with 100M+ atoms or particles. The free Community edition, OVITO Basic, includes many features under an open source license, including the OVITO Python package. The professional edition, OVITO Pro, adds analysis, visualization, and automation functions, such as additional modifiers, support for more file formats, and multiple rendering engines.

OVITO offers a graphical interface for real-time interactive data exploration, quantitative analysis, and 3D visualization. Its pipeline-based workflow supports non-destructive editing. Analysis functions include surface calculation, Voronoi analysis, displacement and strain calculation, atomic structure classification, and microstructural analysis such as grain segmentation and dislocation analysis. Visualization options include spherical, ellipsoidal, and custom particle shapes, trajectory lines, vector glyphs, isosurfaces, and support for periodic boundary conditions.

The OVITO Python package provides a documented Python API for automating data analysis and visualization in a reproducible way, including use from Jupyter notebooks. OVITO is developed by scientists in Germany and has been cited in over 20,000 research publications.
