Interactive Visualization of the Lionman in a Digital Exhibition


The lion man is one of the oldest man-made works of art. The sculpture was carved about 40,000 years ago from mammoth ivory and was found just before the outbreak of the second world war in the Lonetal, at the foot of the Swabian Alb. Within this project we visualize digital scans of the lion man in a close cooperation with the Ulmer Museum in connection to the successful application for Unesco World Cultural Heritage "Ice Age Art". The aim of the project is the development of an interactive Media station which primarily supports an interactive exploration of the lion man, but also the Lonetal as well as the Lonetal caves. Through the media station, the lion man and its place of discovery are interactively explorable through a touch screen. In this context, "comprehensible" 3D visualization is a central aspect, which allows the museum users for the first time to interact with the lion man to view it from all sides and at any magnification level. In addition, virtual cuts can be made through the sculpture to explore the inner structures. This direct touch interaction creates an unprecedented proximity to the sculpture, which today can only be viewed in a glass display case. The 3D visualizations are additionally enriched by textual and visual information to illuminate the origin and discovery history of the lion man.

Multi-Touch Powerwall Visualizaion


The goal of this project is to setup a visualization lab with a high-resolution visualization wall, supporting stereoscopic projection and multi-touch interaction. The system is driven by multiple HD projectors, which receive their input from a high-end rendering cluster. The lab enables demos, multi-user collaborations as well as public outreach.

Funding Source: Carl Zeiss Stiftung. Project Duration: 2014-2017.

CAMILIS - Computer-Aided Minimally Invasive Liver Surgery


Minimally-invasive surgery combines the advantages of open surgery (direct visualisation and direct ultrasound) with those of percutaneous procedures . High spatial instrument guidance accuracy during resection or ablation is essential in order to achieve a R0 situation without compromising FLR. Stereotactic (i.e. computer-assisted) technology will effectively allow precise tracking and guiding of surgical instruments together with a suitable visualisation of anatomical structures and precise orientation relative to the tumour.

Collaborative Visual Exploration and Presentation


Visualization plays a crucial role in many areas of e-Science. In this project, we aim at integrating visualization early on in the discovery process, in order to reduce data movement and computation times. Within many research projects, visualization is currently often established as the last step of a long pipeline of compute and data intensive processing stages. While the importance of this use of visualization is well known, facilitating visualization as a final step is not enough when dealing with e-Science applications. We address the challenges arising from the early collaborations enabled by these in-situ visualizations, and we investigate which role visualization plays to strengthen such collaborations, by enabling a more direct interaction between researchers.
