“…In the creation of a virtual building environment in fire condition the main challenge to be cleared up regards the visualization of flames and smoke spreading. Generally, the spreading process is hard to predict, and therefore, it is simplified in many studies [23]. Moreover, a simple sketch to simulate flames and smoke is not sufficient to study a real fire on emergent evacuation process [24].…”

The problem of emergency evacuation of public buildings intended to accommodate large numbers of people is critical. Modern technologies such as the use of numerical simulations, virtual and augmented reality, and Agent Based models represent an opportunity to study behaviors that are difficult to reproduce in real life (e.g. explosions and fires emergencies). This may allow to improve new and existing structures with respect to such risks and therefore to improve the resilience of modern communities. In this paper, the problem of emergency fire evacuation for an existing school in the hinterland of Milan is studied. A virtual reality-based system for the simulation of fire emergency response will be developed starting from the BIM model and then moving on to a platform that ensures the interaction between human and the virtual simulation environment. The spreading of the flames and smoke is based on fire numerical simulation using computation fluid dynamic (CDF) software. Such simulation method may reproduce realistic fire processes and illustrate smoke movement by describing the configuration of fuel, ventilation, and fire source. The verification of the infrastructure response and the subsequent modification for a better emergency response represent the expected results of the research.

“…Thus, accurate smoke visualization is critically important for effective evacuation and rescue in virtual training. Amongst the existing literatures on smoke visualization [5,[16][17], several simplified methods (e.g. cellular automata, particle systems and random variables) have been used to model the dynamic evolution of smoke, which may be significantly different from the actual situation.…”

Smoke is a leading cause of death in fire. To minimize the potential harm from the smoke hazards in the course of a fire, a rational virtual reality (VR)-based fire training simulator taking full account of the various aspects of smoke hazards has been developed and is described herein. In this simulator, a visualization technique based on volume rendering and fire dynamics data has been especially designed to create a realistic and accurate smoke environment for the purposes of effective virtual training, which allows the trainees to experience a realistic and yet non-threatening fire scenario. In addition, an integrated assessment model of smoke hazards is also established in order to assess the safety of different paths for evacuation or rescue in virtual training, which allows the trainees to learn to identify the safest path. Two case studies of a subway station and a primary school demonstrated a high level of accuracy and smooth interactive performance of the proposed simulator, which is thus shown to be valuable for the training of both people who might become trapped in fire and firefighters engaged in learning the proper rescue procedures.

“…Therefore in the virtual fire drill, accurate smoke simulation is crucial to the success of an effective evacuation or rescue. Some simple methods have been used by researchers to simulate the dynamic evolution of smoke [8][9][10], such as cellular automaton, particle systems and random variables. In order to achieve realistic smoke simulation, it is necessary to combine the important characteristics of smoke, which are its distribution and density.…”

Abstract. Fire is one of the major disasters that often happen in the cities. It causes serious economic losses and casualties. Smoke is the main cause of death in fire and it is difficult to be simulated in the traditional way of fire drill. A multi-role collaborative fire drill simulation system was developed on the basis of virtual reality and server engine technology. The system consists of the client end and the server end. In the client end, the realization of the virtual fire scenes is based on the VIZARD software, which allows the trainees to experience a realistic and yet non-threatening fire scenes. The KBENGINE framework is used to enable multi-role synchronous login, the participants can collaborate in a virtual fire drill without time or space constraints. In order to carry out effective virtual training, Fire dynamics data and three-dimensional rendering technology has been especially designed to create a realistic and accurate smoke environment. The smoke risk evaluation model was introduced to assess the safety of different evacuation routes so that trainees could identify the safest route to escape. The test results show that the system has good performance and high accuracy, which helps trainees learn the knowledge of firefighting in the low-cost, high-security, high-fidelity and repeatable virtual environment, and accumulate the real-world firefighting combat experience.
