Leveraging the Potential of 3D Data in the Ship Lifecycle with Open Formats and Interfaces
International Conference on Computer and IT Applications in the Maritime Industries (COMPIT) <14, 2015, Ulrichshusen, Germany>
This paper presents selected 3D applications from several phases in the lifecycle of a ship that have been implemented by Fraunhofer IGD in recent years. All are built on open standards and not tightly coupled to any software suite of a given 3D CAD vendor. This openness is the key for easy adaptation to any existing IT infrastructure and a high level of flexibility. To illustrate our approach, we present technical details of some of the developed applications as case studies. In the outlook section of the paper, we formulate some tasks for future work including specification of a lightweight exchange format for the maritime sector based on ISO standard JT.
Using Direct-touch Interaction for the Visual Exploration of Profiling Sensor Data

We present a novel software approach for the interactive and integrated visual exploration of sensor data acquired by profiling platforms. The solution combines decent web-technologies and linked interactive 2D and 3D data presentations utilizing a direct-touch interaction metaphor. The user can point with his finger on specific data points and slide through the depth profiles and the time scale. For the visualization and interaction design, widely recognized visualization and interaction principles and techniques like "focus & context" and "overview & detail" were incorporated. Our goal is to facilitate the dynamic exploration of spatio-temporal sensor data, to reduce visual clutter in the user interface and to allow the user to focus in on specific time and depth situations. We present first results of a user study with domain experts (marine researchers). The goal of the study was to prove the design considerations and to investigate the practicability of web-based interactive visualization and direct-touch interaction for analytical tasks. Additionally we tested the suitability of our approach for data exploration tasks on different multi-touch display setups. The study results show, that through the intuitive direct-touch interaction and the linked 2D and 3D visualizations of the data sets, the proposed solution offers a better support to explore profiling data sets, compared to currently available nonintegrated tool sets. The presented approach also reduces the efforts of analytical tasks. While the proposed 3D view of ADCP data was considered very useful for a fast assessment of current conditions in the water column, most of the participants also had problems to fully understand the offered navigation and interaction within the 3D space. Creating an intuitive view navigation in 3D space with direct-touch interaction proved to be rather challenging and needs a careful design.
The 29th Annual European Simulation and Modelling Conference 2015
Annual European Simulation and Modelling Conference (ESM) <29, 2015, Leicester, UK>
In order to visualise the results of a physical simulation and the effect on the related 30 geometry so far only the simulation tools themselves could be applied. A web based application, though, could provide a powerful alternative for an efficient and realistic visualisation of data enabling users to edit the data and to share their results with customers. In the course of the project physical modelling and Simulation with Open Modelica was coupled with a rigid body simulation via the Java Script physics engine Arnmo.js and an X3DOM-based 30 graphical modelling and visualisation. Now it is possible to start and edit physical simulations as well as to view the effect of changes on the behavior of the system in the web-based 3D model.
