#include <vtkTimeSourceExample.h>
Creates a small easily understood time varying data set for testing. The output is a vtkImageData in which the point and cell values vary over time in a sin wave. The analytic ivar controls whether the output corresponds to a step function over time or is continuous. The X and Y Amplitude ivars make the output move in the X and Y directions over time. The Growing ivar makes the number of cells in the output grow and then shrink over time.
