- Description
- Virtual environments have been used to develop fire evacuation training systems which benefit from high levels of graphical realism and various interaction methods. However, virtual environment-based fire evacuation training systems often have limited non player character (NPC) behaviours as realistic fire evacuation models are difficult to build as they require accurate fire science, for example the impact of poisonous gases, smoke, and heat on human behaviour. One solution is the reuse of fire evacuation modelling tools to drive NPC behaviours in virtual environments built with gaming technology. In this paper, a pipeline is proposed to embed human behaviour, based on realistic fire science knowledge, into virtual evacuation training systems. The pipeline starts with 3D building models and extracts simulated human behaviour from fire evacuation simulator tools and then integrates these behaviours into NPC movement scripts for use in a game engine. A case study is presented with 3D modelling in SketchUp, simulated behaviour in FDS + Evac and NPC scripts in Unity3D. Consistent evacuation time was found on overall egress time in both FDS+Evac and Unity3D. A scalability analysis of environment complexity showed a linear increase in evacuation time by scenario scale in Unity3D and FDS+Evac.
