Varela, J.M. and Guedes Soares, C. (2017), “Geometry and visual realism of ship models for digital ship bridge simulators”, Journal of Engineering for the Maritime Environment, 2017, Vol. 231(1), pp. 329-341
In this paper, we address the main requirements and the process of creating the geometry of ship models that fulfil the highly demanding request for realism and performance of the Virtual Environments currently used in modern Ship Bridge Simulators. We start with a classification of the ships based on their role in the simulation, on the type of simulator used, and define the main characteristics of the models. We also discuss the importance of a well-defined workflow and its impact on the modelling time and on the quality of the final product. The paper provides contributions in the following areas: identification of the main requirements of polygonal models of ships for ship simulators; effective workflow for ship 3D modelling; identification of most suitable modelling techniques for efficient creation of ship models. The study is supported by real examples of 3D modelling of ships with different sizes and characteristics currently used by the ship manoeuvring simulator in the Centre for Marine Technology and Ocean Engineering of the University of Lisbon.
