Virtual Reality Application in a Crisis Scenario Model

Weather changes, ecological and terrorist threats, increased mobility of the population, cross-border activities, structural changes of the wealth are actual trends in our modern world. The new risks, threats and crises which arise nowadays require modern knowledge based instruments in order to predict, to avoid, to manage and to decrease the impact of these events. These modern instruments are developed on the basis of the experience regarding a category of crises and rely on modern information technologies which offer the necessary edge.virtual reality, crises, information technologies

DISTRIBUTED 3D INFORMATION VISUALIZATION Towards Integration of the dynamic 3D graphics and Web Services

Abstract: This paper focuses on visualization and manipulation of graphical content in distributed network environments. The developed graphical middleware and 3D desktop prototypes were specialized for situational awareness. This research was done in the LArge Scale COllaborative decision support Technology (LASCOT) project, which explored and combined software technologies to support humancentred decision support system for crisis management (earthquake, tsunami, flooding, airplane or oil-tanker incidents, chemical, radio-active or other pollutants spreading, etc.). The performed state-of-the-art review did not identify any publicly available large scale distributed application of this kind. Existing proprietary solutions rely on the conventional technologies and 2D representations. Our challenge was to apply the "latest " available technologies, such Java3D, X3D and SOAP, compatible with average computer graphics hardware. The selected technologies are integrated and we demonstrate: the flow of data, which originates from heterogeneous data sources; interoperability across different operating systems and 3D visual representations to enhance the end-users interactions.
