GPSS/PC graphics and animation

GPSS/PC is a popular implementation of the discrete event simulation language GPSS, the General Purpose Simulation System. GPSS/PC has interactive graphics and animation tightly integrated into its simulation environment. Its graphics windows allow viewing and manipulation of the simulation via an optional pointing device, and assertion of all simulation primitives. All windows are online, providing for a visualization of model dynamics, and one of the windows allows animations of the simulation to be played out in an essentially unbounded virtual screen. A CAD based animation postprocessor is now available which can create a detailed 3D animation based on a previously recorded GPSS/PC animation. Using the postprocessor, the animation space can be placed in 3D, and an arbitrary amount of detail can be added to the objects and layout of the animation. A variety of rendering and speedup options are then available. This tutorial presents the interactive graphics, built-in animation, and CAD based postprocessor animation available with GPSS/PC.
