First-time mathematical formulation by IST Austria computer science professor Bernd Bickel solves problem of technical modelling
During the annual top conference of the Special Interest Group for Computer Graphics (SIGGRAPH) of the Association for Computing Machinery (ACM), which took place in Anaheim, USA, IST Austria Professor Bernd Bickel and his group present an algorithm that allows improved technical modelling of planar-rod structures consisting of interlocking wires.
After designing an aesthetically pleasing structure, e.g. a car or a duck, the contours of the objects are re-calculated with the new algorithm.
In this way, necessary adaptions of the structure and its connection points are computed to guarantee optimal stability of the object fabricated by the wire bending machine. The 2D structures are assembled to a 3D object without requiring additional connectors or soldering points.
"We were able to find a mathematical formulation for an exciting problem which allowed us to solve this problem in a second step. The software can be a useful tool for designers and engineers", says Bernd Bickel concerning the recently developed algorithm.
The software implies applications to art on the one hand, but wire sculptures on the other hand present an extremely efficient and fast alternative for low-fidelity rapid prototyping due to the manufacturing time and required material scaling up linearly with the physical size of objects. The software allows a verification of function and stability resulting in the production of the optimal object only.
Bernd Bickel joined IST Austria as an Assistant Professor in 2015. Beforehand he obtained his Master's degree in Computer Science from ETH Zurich in 2006. For his PhD studies, he joined the group of Markus Gross, a full professor of Computer Science at ETH Zurich and the director of Disney Research Zurich. From 2010 to 2012 Bickel was visiting professor at TU Berlin and then became a research scientist and research group leader at Disney Research Zurich, where he investigated approaches for simulating, designing, and fabricating materials and objects. 2015 he received the Microsoft Visual Computing Award.
His research interest focuses on computer graphics and its overlap with animation, biomechanics, material science, and digital fabrication. His main objective is to push the boundaries of how digital content can be efficiently created, simulated, and reproduced using advanced 3D printing technology.
Together with other IST Austria Professors he launched the Visual Computing @ IST Austria platform to make this strong research focus at IST Austria more visible.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
