Viewports are windows to the three-dimensional scene that you work in. OVITO provides four viewports, laid out in a two by two grid, which simultaneously show the same scene from different angles. The caption in the upper left corner of each viewport and the axis tripod in the lower left corner indicate the orientation of the virtual camera associated with a viewport.
The viewport toolbar is located below the viewports and contains buttons to activate various navigation input modes. In addition, you will find two other useful functions here:
The Zoom Scene Extents function automatically adjusts the zoom level and repositions the camera of the active viewport such that the complete scene becomes fully visible. The currently active viewport is marked by a yellow border.
The Maximize Active Viewport button enlarges the active viewport to fill the entire main window. Clicking the button a second time restores the original 2x2 viewport layout.
