Modifiers are the basic building blocks that can be used in OVITO's processing pipeline. The following table lists the available modifier types.
| Modifier name | Description |
|---|---|
| Analysis | |
| Atomic strain | Calculates the atomic-level strain tensors based on an initial reference and a deformed configuration. |
| Bond-angle analysis | Performs the bond-angle analysis of Ackland and Jones to determine the local crystal structure. |
| Construct surface mesh | Constructs a polyhedral mesh representing the surface of an atomistic solid. |
| Displacement vectors | Calculates the displacements of particles based on an initial and a deformed configuration. |
| Centrosymmetry parameter | Calculates the centrosymmetry parameter for every particle. |
| Cluster analysis | Decomposes a particle system into clusters of particles. |
| Common neighbor analysis | Performs the common neighbor analysis (CNA) to determine the local crystal structure. |
| Coordination analysis | Determines the number of near neighbors of each particle and computes the radial distribution function. |
| Histogram | Computes the histogram of a particle property. |
| Scatter plot | Generates a scatter plot of two particle properties. |
| Wigner-Seitz defect analysis | Identifies point defects (vacancies and interstitials) in a crystal lattice. |
| Coloring | |
| Ambient occlusion | Performs an ambient occlusion calculation to shade particles. |
| Assign color | Assigns a color to all selected particles. |
| Color coding | Colors particles based on a certain particle property. |
| Modification | |
| Affine transformation | Applies an affine transformation to particle coordinates. |
| Create bonds | Creates bonds between particles. |
| Compute property | Computes a new property for each particle based a user-defined formula. |
| Delete selected particles | Deletes all selected particles. |
| Freeze property | Takes a snapshot of the current state of a particle property and preserves it over time. |
| Show periodic images | Duplicates particles to display the periodic images of particles. |
| Slice | Cuts out a slice or a cross-section from the structure. |
| Wrap at periodic boundaries | Maps particles outside of the simulation box back into the box. |
| Selection | |
| Clear selection | Resets the selection state of all particles. |
| Freeze selection | Preserves the current selection state over time. |
| Manual selection | Allows to select particles with the mouse. |
| Invert selection | Inverts the selection state of each particle. |
| Expression select | Selects particles based on a user-defined criterion. |
| Select particle type | Selects particles of one or more types. |
