Project
Digital Urban Mining Platform: Assessing the material composition of building stocks through coupling of BIM to GIS
Michael Wimmer -

The strong population growth and urbanization are increasing the global resources and energy consumption. The AEC (architecture, engineering and construction) industry is responsible for 60% of the extracted raw materials and generates 40% of the energy-related CO2 emissions. In Austria, the AEC sector is responsible for 70% of total annual waste – facts that are underlining the importance of implementing recycling strategies.

BIM-based digital Plattform for design and optimisation of flexible facilities for Industry 4.0
Hannes Kaufmann -

Industrial Building Design is a design process where the successful implementation of each project is based on collaborative decision making of multiple domain specialists - architects, engineers, production system planners and building owners. Traditionally, such multi-collaborator workflows are subject to conflicting stakeholder goals and frequent changes in production processes inevitably resulting in lengthy planning periods.

Superhumans - Walking Through Walls
Stefan Ohrhallinger -
In recent years, virtual and augmented reality have gained widespread attention because of newly developed head-mounted displays. For the first time, mass-market penetration seems plausible. Also, range sensors are on the verge of being integrated into smartphones, evidenced by prototypes such as the Google Tango device, making ubiquitous on-line acquisition of 3D data a possibility. The combination of these two technologies – displays and sensors – promises applications where users can directly be immersed into an experience of 3D data that was just captured live.

Scenario Pool: Visual Analytics for Action Planning in the Presence of Uncertainty
Jürgen Waser -

Natural hazards such as floods are likely to occur more often in the near future. Modern information technology can simplify the workflow of disaster management. However, none of the existing tools is tailored to the requirements of action planning. The major challenge lies in the sheer quantity of complex information the planner has to account for. The choice of the right action at the right time depends on a variety of factors and cannot be automated. Moreover, since the course of events cannot be exactly predicted, numerous, alternative scenarios have to be considered.

KASI: Knowledge Assited Sparse Interaction for Peripheral CT
Eduard Gröller -
The knowledge assisted sparse interaction proposed above is a general paradigm, applicable to any area of visualization. However, within the framework of the current proposal we want to specialize predominantly on one of these possibilities, namely on the processing and diagnostics of the peripheral artery occlusive disease (PAOD) within the context of noninvasive CT angiography [1]. PAOD is a significant health problem in the industrialized world, with a prevalence of 8-12 million cases in the US alone [32]. The number of such cases is expected to increase as the population ages.

TERAPOINTS - High Quality Visualization and Interaction with Gigantic Point Data Sets
Michael Wimmer -
Laser scanning is an important tool in cultural heritage for documenting the state of archaeological monuments. The data produced by laser scanning is ever increasing, with the latest generation of laser scanners generating a billion of points in one measurement pass. To colorize the laser scans, additional photographs are taken. Managing these huge amounts of data in terms of size is a challenge on its own, but also to ensure the quality of the resulting point-based models is of utmost importance for the further development of laser scanning as a standard technique in cultural heritage. We identified three topics that can drive forward the integration of laser scanning in the everyday work of archaeologists.

Solving the visibility problem has been an important research topic for many years, and countless methods have been proposed.
