A Graphical Simulation Management System

Abstract

In this paper we describe the design and implementation of a system for the management of complex interactive graphical dynamical simulations. The main objective of the system is to provide tools which enable a graphical simulation to be built with minimum effort. These tools include routines for building interfaces (panels consisting of buttons, sliders, type in boxes, etc.), arranging the simulation workspace, describing complex 3D objects in terms of predefined (or user defined) primitives, and providing objects with properties used in conjunction with lighting models.<P>The need for such a management system is supported by the facts that both the development effort and the extent of machine-specific knowledge needed to successfully implement an arbitrary graphical simulation is significant. It is the aim of the Graphical Simulation Management System (GSMS) to reduce these burdens and place the power of 3D simulation within easy reach.<P>We have presented several examples of dynamical simulations in which the power and diversity of the management system is demonstrated.
