Animations

aiSee can be used as an animation handler to animate a sequence of graph specifications. A program can continuously output GDL specifications to a file. When the program has produced one instance of output, it informs aiSee that the graph specification is available. Then aiSee displays the new instance of the graph. After visualization, aiSee indicates completion to the program generating the graph specifications, thus enabling the program to output the next graph specification.

Consequently, the program and aiSee represent a client-server model. The program calls aiSee with the option -a <num> . After relayout aiSee sleeps <num> seconds, then it attempts a callback to the parent process.

aiSee has to have been started with the option -ddemsg option. Then the program and aiSee communicate with one another via a DDE channel as a server and client.
