Welcome



Welcome to the Virtual Reality & Immersive Visualization Group
at RWTH Aachen University!

The Virtual Reality and Immersive Visualization Group started in 1998 as a service team in the RWTH IT Center. Since 2015, we are a research group (Lehr- und Forschungsgebiet) at i12 within the Computer Science Department. Moreover, the Group is member of the Visual Computing Institute and continues to be an integral part of the RWTH IT Center.

In a unique combination of research, teaching, services and infrastructure, we provide Virtual Reality technologies and the underlying methodology as a powerful tool for scientific-technological applications.

In terms of basic research, we develop advanced methods and algorithms for multimodal 3D user interfaces and explorative analyses in virtual environments. Furthermore, we focus on application-driven, interdisciplinary research in collaboration with RWTH Aachen institutes, Forschungszentrum Jülich, research institutions worldwide, and partners from business and industry, covering fields like simulation science, production technology, neuroscience, and medicine.

To this end, we are members of / associated with the following institutes and facilities:

Our offices are located in the RWTH IT Center, where we operate one the largest Virtual Reality labs worldwide. The aixCAVE, a 30 sqm visualization chamber, makes it possible to interactively explore virtual worlds, is open to use by any RWTH Aachen research group.

ICT Young Researcher Award 2017 for Andrea Bönsch

By means of a yearly award, the profile area "Information and Communication Technology" at RWTH Aachen University honors young researchers who contribute significantly to the ICT-related research and show the potential to further improve the international visibility of ICT research at RWTH Aachen University. Andrea Bönsch was selected by the Steering Committee of the profile area ICT as one of the recipient of the 2017 ICT Young Researcher Award. The award is donated with 3000 Euro, supporting her research career.
Congratulations!

Successful Event „VR in Industry“

Due to the current hype of the discipline of Virtual Reality (VR) evoked by top-quality and affordable VR devices on the markets, some issues arise in Industry: How can VR be optimally integrated into the existing processes? Which hardware and software are required? Which costs are incurred for a company?

To answer these questions we teamed up with the TEMA Technologie Marketing AG, and organized as well as partially hosted "The VR in Industry Days in Aachen" on July, 4th to 5th.

Profile Area Information and Communication Technology now on LinkedIn

The Profile Area Information and Communication Technologies (ICT) plays an important role in all global challenges the institutional strategy of RWTH Aachen University addresses. Major topics of ICT such as Smart Systems, eHealth & AAL, Wireless Communication or Data Mining have an enormous research potential and a considerable practical relevance. However, the challenges occurring in this fields can only be solved on an interdisciplinary level. Therefore, the RWTH Aachen University founded the interdisciplinary Profile Area ICT with the respective Project House ICT Foundations of a Digitized Industry, Economy, and Society. Both, the Visual Computing Institute as well as the Chair of Computer Science 12, are members of this Project House with, in total, three projects.

In order to share and discuss ICT related information, the Profile Area ICT now has a LinkedIn presence. So, visit our profile and follow us on LinkedIn.

Interactive Exploration of Dissipation Element Geometry

Eurographics Symposium on Parallel Graphics and Visualization (2017)

Dissipation elements (DE) define a geometrical structure for the analysis of small-scale turbulence. Existing analyses based on DEs focus on a statistical treatment of large populations of DEs. In this paper, we propose a method for the interactive visualization of the geometrical shape of DE populations. We follow a two-step approach: in a pre-processing step, we approximate individual DEs by tube-like, implicit shapes with elliptical cross sections of varying radii; we then render these approximations by direct ray-casting thereby avoiding the need for costly generation of detailed, explicit geometry for rasterization. Our results demonstrate that the approximation gives a reasonable representation of DE geometries and the rendering performance is suitable for interactive use.

 

A Task-Based Parallel Rendering Component For Large-Scale Visualization Applications

Eurographics Symposium on Parallel Graphics and Visualization (2017)

An increasingly heterogeneous system landscape in modern high performance computing requires the efficient and portable adaption of performant algorithms to diverse architectures. However, classic hybrid shared-memory/distributed systems are designed and tuned towards specific platforms, thus impeding development, usage and optimization of these approaches with respect to portability. We demonstrate a flexible parallel rendering framework built upon a task-based dynamic runtime environment enabling adaptable performance-oriented deployment on various platform configurations. Our task definition represents an effective and easy-to-control trade-off between sort-first and sort-last image compositing, enabling good scalability in combination with inherent dynamic load balancing. We conduct comprehensive benchmarks to verify the characteristics and potential of our novel task-based system design for high-performance visualization.

 

Measuring Insight into Multi-dimensional Data from a Combination of a Scatterplot Matrix and a HyperSlice Visualization

International Conference on Digital Human Modeling and Applications in Health, Safety, Ergonomics and Risk Management 2017

Understanding multi-dimensional data and in particular multi-dimensional dependencies is hard. Information visualization can help to understand this type of data. Still, the problem of how users gain insights from such visualizations is not well understood. Both the visualizations and the users play a role in understanding the data. In a case study, using both, a scatterplot matrix and a HyperSlice with six-dimensional data, we asked 16 participants to think aloud and measured insights during the process of analyzing the data. The amount of insights was strongly correlated with spatial abilities. Interestingly, all users were able to complete an optimization task independently of self-reported understanding of the data.
