We've implemented something like that so that we can have snapshots taken at preset times and saved to files. It's done by adding a new method to Display2D.java: takeSnapshot(String filename). You can then call this method whenever you like and feed it a String for the filename. I've attached our modified file. The new method is right after the original takeSnapshot(). -Paul Smaldino [log in to unmask] On Mon, May 3, 2010 at 9:33 AM, Mark Coletti <[log in to unmask]> wrote: > It is possible to save a snapshot of a simulation from the GUI.
