Made for particle simulations
of any scale
Accelerate your research
Explore simulations of any kind and size interactively – from ab initio models with a handful of atoms to large-scale simulations with 100M+ particles.
Trusted by researchers worldwide
Cited in more than 20,000 research publications, with 10+ new papers every day.
OVITO Basic: free and open source
A rich set of visualization and analysis functions, free of charge under an open source license – together with the OVITO Python package.
OVITO Pro: the professional edition
Adds an AI agent, exclusive analysis modifiers, ray-tracing engines, and Python automation – everything you need to get more done in less time.
Powerful features
Imports the file formats of all major simulation codes – LAMMPS, VASP, GROMACS, Quantum ESPRESSO, and many more
Intuitive graphical user interface for interactive data exploration, quantitative analysis, and 3D visualization
Non-destructive pipeline workflow: change any analysis step at any time and see the result instantly
Handles atomistic, molecular, and granular models as well as grid-based and mesh-based data
Comprehensive documentation, tutorials, and an active user community
Analysis functions
Geometric surface calculation, pore & cavity analysis
Microstructural analysis tools such as grain segmentation, dislocation analysis (DXA), and defect identification
Interactive measurement of distances, angles, and areas
And many more – browse the complete list of modifiers
Visualization
Spherical, ellipsoidal, super-ellipsoidal, and custom particle shapes
Protein cartoon representation and text labels in the 3D scene
Full support for periodic boundary conditions and non-orthogonal simulation cells, including virtual periodic images
OVITO Python package
Powerful, well-documented Python API – free and open source
Automate your analysis and visualization tasks – reproducibly
Use OVITO in Jupyter notebooks, including interactive 3D viewer widgets
Run on HPC compute nodes, servers, and in containers – image rendering works without a display
Integrate file I/O, analysis, and visualization functions into your own workflows and software
Let OVITO Pro write ready-to-run Python scripts for you
High-quality rendering
Fast, GPU-accelerated real-time viewports using Direct3D 12, Metal, or Vulkan
Shadows, ambient occlusion, depth of field, and fog – in the viewports and in rendered images
Ray-tracing engines in OVITO Pro for compelling scientific illustrations and animations
Multi-viewport layouts for comparative visualizations
Export 3D models to the web, PowerPoint, or Blender
OVITO Pro
The professional edition for academic and industrial research – developed by expert scientists in Germany since 2009
AI agent integration
Connect AI coding agents such as Claude Code, GitHub Copilot CLI, or OpenAI Codex to your live OVITO Pro session. Describe an analysis in plain language and let the agent build the pipeline.
Exclusive analysis modifiers
Diffusion coefficient, Bader charge integration, bond order, ring finder, spatial binning, time averaging & time series, volumetric region analysis, and more.
Ray-tracing rendering engines
Tachyon, OSPRay, and NVIDIA VisRTX for publication-quality images and movies – on CPUs and GPUs.
Python code generation
Turn your interactively built pipelines into ready-to-run Python scripts.
Python extensions
Extend OVITO with your own modifiers, file readers and writers, viewport layers, and utility applets - or install ready-made ones from the extensions directory.
Multiple pipelines
Add several simulations to one scene for comparative analysis, and use pipeline branching for efficient data processing.
Extended LAMMPS integration
Run LAMMPS scripts from within OVITO for quick simulation prototyping, and visualize LAMMPS regions.
Additional file formats
ASE database and trajectory import, and glTF 3D scene export for the web, PowerPoint, and Blender.
Remote data access
Load simulation data directly from remote computers via SSH, including smartcard and 2FA authentication.
