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.

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.

Smart Communities and Technologies: 3D Spatialization
Michael Wimmer — since

The Research Cluster "Smart Communities and Technologies" (Smart CT) at TU Wien will provide the scientific underpinnings for next-generation complex smart city and communities infrastructures. Cities are ever-evolving, complex cyber physical systems of systems covering a magnitude of different areas. The initial concept of smart cities and communities started with cities utilizing communication technologies to deliver services to their citizens and evolved to using information technology to be smarter and more efficient about the utilization of their resources.

Project
Fotos mit Structure-From-Motion zu Punktwolke und mit unserer Rekonstruktion weiter zu Mesh Photogrammetry made easy
Philipp Erler -

Dieses Projekt richtet sich an alle Menschen, die gerne etwas in der echten Welt einscannen und anderen Menschen als 3D-Modell zeigen wollen. Beispielsweise könnte ein Artist unterwegs eine interessante Skulptur finden und diese in ein Spiel einbauen oder als Miniatur ausdrucken. Raumplaner könnten z.B. eine Kreuzung einscannen, nach ihren Plänen verändern und diese damit besser kommunizieren.

Semantic Modeling and Acquisition for Urban Safety Simulations
Michael Wimmer -

This project aims at analysing the traffic flow of open roads in real time by a sensor fusion of radar data with video feeds. Radar gives an accurate position and velocity of vehicles making computer vision methods more robust in computing their spatial extent and classification from video streams. In this way the huge amount of raw data is reduced to semantically relevant information, which is highly memory efficient, anonymous and sufficient to reconstruct traffic flow over long time periods.

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.
Visual Computing in Fundamental, Academic and Applied Science and Research
Werner Purgathofer -
Visual Computing is an emerging field of research, formed by the progressive fusion of traditionally separate scientific fields. Visual Computing deals with problems that are focused on processing or acquisition of graphical data. Most visual computing researchers work in the fields of computer graphics, digital image processing, pattern recognition, visualization and virtual reality. Since many new technologies and problems require expertise in several of these fields, research groups increasingly look for opportunities to improve their cooperation with neighboring fields.

General Purpose Visibility
Michael Wimmer -

Visibility culling is a fundamental problem of computer graphics, and is of crucial importance for many applications, like game development or architectural design. For example, interactively rendering a model containing hundreds of millions of polygons like the Boeing 777 model shown on the cover page is only possible when invisible parts of the model are "culled" away. Solving the visibility problem has been an important research topic for many years, and countless methods have been proposed.
