Abstract

Currently, games with rich environments allowing a wide range of possible interactions and supporting a large number of physical simulations make use of a large number of scripts and bespoke physical simulations, adapted to fit the needs of the game. This thesis proposes a methodology that can be used to tie together various different physical simulations, both off-the-shelf and bespoke, such as rigid body physics, electrical and magnetic simulations to give something greater than the sum of the individual parts. We present a notation for designing the overall physical simulation and a means for the different parts to interact. Experiments using an implementation of the methodology containing electricity, rigid body simulation, magnetics (including electro-magnetics), buoyancy and sound show that it is possible to model everyday objects such an electric motor or a doorbell. These object work ‘as expected’, without the need for special scripts and new, originally unexpected, interactions are possible without further modification of the experiment setup.
