BIM based visualisation support integrated with VR interfaces

The current deliverable D3.4 “BIM based visualisation support integrated with VR interface” aims at documenting the technical activities that were undertaken towards the definition of the second and final iteration of the Building Information Model (BIM) that was developed in the context of the S&R project and will be useful tool for the first responders during a search and rescue operation. The BIM model comprises a RESTful web service that exposes specific interfaces with the aim of representing building data and a Building semantic model that facilitates the data manipulation towards the creation of the necessary correlations towards the representation of the Building semantic model. The present deliverable will document the core components and the specific requirements of the web service, as well as the completed semantic model for the building data. In this frame, a RESTful web service is implemented to facilitate the building data manipulation towards the creation of the necessary correlations which constitute the semantic model. These correlations will be defined in order for the first responders to have a clear overview of the building during a S&R operation. Finally, the main functional components of the BIM management system are introduced, as well as the process of the BIM model data visualization through the VR technology devices of S&R that allows the first responder to obtain a well-defined conceptual model of the buildings, geometric properties and structural elements in the field.
