Saving and restoring program state

The complete working state of the program, including the viewports, the modification pipeline, and display settings, can be saved to a state file by choosing FileSave Program State from the menu. This allows you to continue working at a later time and to preserve the current visualization setup for future use. For instance, you can use a state file as a template to visualize multiple simulations using the same camera setup and modifier sequence.

Keep in mind that OVITO does not store any simulation data in the state file by default to keep it small. It only saves a reference to the original simulation data file that was imported into OVITO, and the data is restored from that external file when you load the state file.

Spinner widgets

A spinner is a graphical user interface element used in the program to let you change numeric parameters (see screenshot on the right). Here is how you use the spinner widget. You can click or drag the spinner's up and down arrows to change the value in the adjacent text box. Do one of the following:

  • Click the spinner's up arrow to increment the value; click the down arrow to decrement the value in a stepwise manner.

  • Click and hold for continuously changing the value. Drag upward to increase the value, or drag downward to decrease it. For continuous parameters this is often the fastest method.

Particle inspection utility

The "Utilities" tab of OVITO's command panel, which is shown in the screenshoft on the right, contains the Particle Inspection utility for displaying the properties of individual particles. The tool also allows you to measure distances between pairs of particles.

There is also a utility on the same command panel tab that lets you visualize particle trajectory lines.
