Varela, J., Santos, T.A. and Guedes Soares, C. (2003), “Simulation of Fluid Dissemination in a Virtual Reality Environment Onboard the Ship”, Proceedings of the 2nd International Conference on Computer Applications and Information Technology in the Maritime Industries (COMPIT'03), 14-17 Maio, Hamburgo, Alemanha, pp. 432-44

The paper addresses the simulation of fluid dissemination in a ship, using a 3D environment of visualization and control coupled to a simulation algorithm, originating a virtual reality application. The virtual reality environment was developed apart from the simulation algorithm using a generic architecture based on the object-oriented paradigm. The architecture allows adapting the model data structure in order to make the connection to the algorithm. The object-oriented approach is currently the most used way to achieve an efficient production of high quality reusable software. The abstraction offered by this technique hides subsets of existing complex processes and decreases the difficulty of dealing with highly complex systems. The algorithm was also developed apart from the virtual reality environment. It loads the data provided by the virtual reality application in order to run each cycle. The data is then updated and displayed in the 3D environment. The object in study is a virtual world composed by a vessel with several watertight compartments connected by doors, valves, hatches, pipes and ventilation ducts. The purpose of this virtual model is the study, visualization and control of fluid dissemination along the vessel in a casualty situation.
