OVITO is a scientific visualization and analysis software for large-scale atomistic simulation data.
Its design is platform-independent, extensible, and flexible. The source code is freely available under an open-source license.
OVTIO is being developed by Alexander Stukowski from the materials modeling group at the University of Darmstadt, Germany.
In its current form OVITO is best suited for the visualization and analysis of molecular dynamics
simulations of atomic systems, especially solid-state materials. Here is a non-complete list of
features:
- It's free, open source software
- Platform independent design
- Imports several file formats including LAMMPS, XYZ and POSCAR
- Realtime rendering of large systems using hardware accelerated OpenGL graphics
- Flexible data model: allows to associate an abitrary number of properties with each atom
- Flexible processing model: Modification and analysis steps can be performed in any order, parameters can be altered at any time:
- Slicing
- Selection of atoms based on user-definable criteria
- Color coding
- Transformation of atomic positions
- Display of periodic images; wrapping of atoms at periodic boundaries
- Unlimited undo functionality
- Production of images for publication
- Visualization of multiple timesteps (realtime playback or movie image sequence)
- Powerful analysis functions including
- Common neighbor analysis
- Cluster analysis
- Coordination number analysis
- Displacement vector calculation
- Calculation of extrinsic strain tensors at the atomic level
- Calculation of intrinsic strain tensors at the atomic level
- Export of atomic data files as input for new simulations
- Python based scripting interface enables batch-processing directly on the computer cluster
- A modular software design makes it easy to extend OVITO via plugins written in C++
