VisIt provides a keyframing mode that makes it possible for the user to define how plot attributes and the view change dynamically over time. Since keyframing can be difficult to set up, this page provides a simple example that lets you set up a plot whose opacity changes over time. Once a keyframe animation has been set up, you can use the "Simple movie" option in VisIt's Save movie wizard to create a movie file containing the animation.
Making plot keyframes
Now that the visualization window is in Keyframe mode, you can make plot keyframes.
Making view keyframes
In addition to keyframing plot attributes, VisIt allows you to create keyframed views. Keyframed views can be useful for zooming into areas of interest or flying into a visualization while it plays. Simple types of view rotations are better handled in the Save movie wizard by making a custom movie template.
The controls for making view keyframes are located in the View window, which is accessible from the Controls menu in the Main window. There are two controls that are of interest when creating view keyframes. The first one is the Make camera keyframe from view button located in the 'Advanced' tab. When that button is clicked, VisIt adds the current view as a view keyframe for the current animation frame. If you want the view to change when you animate through time, you must also turn on the Copy view from camera check box and click the Apply button. The Copy view from camera check box causes VisIt to copy the interpolated keyframe view into the camera used to render the visualization.
In order to add view keyframes in the context of the above example, do the following:
