Data objects
A dataset loaded into OVITO from a simulation file may consist of several individual data objects, which represent different facets of the information, e.g. the simulation cell geometry, the atomic coordinates, the bond list, etc. Modifiers operate on these data objects and may add dynamically computed data objects to the dataset as it is processed in the data pipeline.
Note that, in OVITO, the visualization of data is delegated to so-called visual elements, which are responsible for producing the three-dimensional graphical representation of the numerical data stored in the data objects. That means data objects themselves have no configurable visualization parameters; only the visual elements rendering the graphical representation do.
