Complex 3D data on all devices (Graphics)
Posted by: Site Administration
A new web-based software platform is swiftly bringing the visualization of 3D data to every device, optimizing the use of, for example, virtual reality and augmented reality in industry. In this way, Fraunhofer researchers have brought the ideal of “any data on any device� a good deal closer.

U-M paleontologists unveil online showcase of 3-D fossil remains (Graphics)
Posted by: Site Administration
More than two decades ago, University of Michigan paleontologist Daniel Fisher and some of his students began the laborious task of digitally scanning the bones of mastodons, mammoths and other prehistoric creatures so the images could be displayed on computers.

3D X-ray Film: Rapid Movements in Real Time (Graphics)
Posted by: Site Administration
How does the hip joint of a crawling weevil move? A technique to record 3D X-ray films showing the internal movement dynamics in a spatially precise manner and, at the same time, in the temporal dimension has now been developed by researchers at ANKA, KIT’s Synchrotron Radiation Source. The scientists applied this technique to a living weevil. From up to 100,000 two-dimensional radiographs per second, they generated complete 3D film sequences in real time or slow motion.

Modelling the Duynamics of the Skin (Graphics)

You know how your fingers wrinkle up in the bath? The outer layer of your skin absorbs water and swells up, forming ridges – but quickly returns to its old state when dry. Two physicists, Professor Roland Roth of Tübingen University and Dr. Myfanwy Evans at Erlangen University have shown just why skin has this remarkable ability. Their conclusions were published recently in the journal Physical Review Letters.

CCNY Team Models Sudden Thickening of Complex Fluids (Graphics)
Posted by: Site Administration
A new model by a team of researchers with The City College of New York’s Benjamin Levich Institute may shed new understanding on the phenomenon known as discontinuous shear thickening (DST), in which the resistance to stirring takes a sudden jump. Easily observed in a ‘kitchen experiment’ by mixing together equal amounts of cornstarch and water, DST occurs because concentrated suspensions of hard particles in a liquid respond differently than normal fluids to shear forces.

Visualizing the past: Nondestructive imaging of ancient fossils (Graphics)
Posted by: Site Administration
By integrating high-resolution X-ray imaging (termed microCT), 3D image segmentation, and computer animation, a new study conducted by Carole Gee at the University of Bonn, Germany, demonstrates the visualization of fossils without destroying the material. Traditional techniques, such as thin-sectioning, require investigators to physically cut up the fossil in order to observe internal structures. Dr. Gee, however, has now successfully applied microCT to visualize silicified conifer seed cones as old as 150 million years without cutting, sawing, or damaging the specimens in any way.

Figuring Out Flow Dynamics (Graphics)
Posted by: Site Administration
Since 2006, Beverley McKeon, professor of aeronautics and associate director of the Graduate Aerospace Laboratories at the California Institute of Technology (Caltech) and collaborator Ati Sharma, a senior lecturer in aerodynamics and flight mechanics at the University of Southampton in the U.K., have been working together to build models of turbulent flow. Recently, they developed a new and improved way of looking at the composition of turbulence near walls, the type of flow that dominates our everyday life.
