Rendering and Modeling

Since the very beginning of the Institute, a major part of our research topics dealt with rendering and modeling. Here you can get an overview of all the projects that fall within that category. We are also working on real-time rendering and procedural modeling, especially in the context of urban visualization.

Research Projects

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.

Modeling the World at Scale
Stefan Ohrhallinger -
Vision: reconstruct a model of the world that permits online level-of-detail extraction.
Advanced Computational Design
Michael Wimmer, Michael Wimmer, Hannes Kaufmann -

Research question: The main research question addressed by the SFB Advanced Computational Design is how to advance design tools and processes through multi- and int

Wohnen 4.0 - Digital Platform for Affordable Housing
Michael Wimmer -

This is a joint project with the civil engineering faculty and several companies. Its aim is the development of an Integrated Framework “Housing 4.0”; a digital platform supporting integrated planning and project delivery through coupling various digital tools and databases, like Building Information Modeling (BIM) for Design to Production  and Parametric Habitat Designer.

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.
Advanced Visual and Geometric Computing for 3D Capture, Display, and Fabrication
Michael Wimmer -
This Marie-Curie project creates a leading European-wide doctoral college for research in Advanced Visual and Geometric Computing for 3D Capture, Display, and Fabrication.
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.

Real-Time Shape Acquisition with Sensor-Specific Precision
Michael Wimmer -
Acquiring shapes of physical objects in real time and with guaranteed precision to the noise model of the sensor devices.

Research Areas

Research Area
Perception
In computer graphics we produce images, videos and other content that is perceived by humans. Unfortunately, human perception is still not well understood, making it hard to design algorithms that perfectly fit a user’s needs. Understanding how people see, do and perceive things is therefore a key component when optimizing and creating new rendering algorithms.
Rendering
In this area, we concentrate on algorithms that synthesize images to depict 3D models or scenes, often by simulating or approximating the physics of light.
Fabrication
The advent of consumer-grade 3D printing has recently sparked interest in fabrication-aware shape design and optimization. We use techniques from computer graphics and engineering to develop new computational tools to facilitate the design process of physical artifacts.
Modeling
In this area, we focus on researching methods and algorithms that facilitate creation, representation, analysis and processing of 3D models.
Geometry Processing
Uses concepts from applied mathematics and computer science to design efficient algorithms for the reconstruction, analysis, manipulation, simulation and transmission of complex 3D models. Example applications are collision detection, reconstruction, compression, occlusion-aware surface handling and improved sampling conditions.
