Imagine shopping online for the perfect back-to-school outfit. You can see the colour and size and perhaps the texture of the fabric, but can you tell how it will look from different perspectives under fluorescent classroom lighting?
"The material might be very beautiful but a potential customer wouldnt know that because the image gives a grossly incomplete sense of texture," says Alex Vasilescu, a doctoral candidate at U of Ts Department of Computer Science. The software she has developed, called TensorTextures, requires just a few sample images of any surface with complex three-dimensional relief, such as luxurious velvets or shimmering silks. Using that information, it can render the true appearance of the surface from every possible viewpoint and under any illumination.
TensorTextures could be adapted for the Web and filmmaking and could possibly be introduced commercially within a year, says Vasilescu. The software is described in a study presented at the SIGGRAPH 2003 conference on computer graphics and interactive techniques in San Diego July 31.CONTACT: Alex Vasilescu, Department of Computer Science (currently at the Media Research Lab, New York University) 212-998-3320, firstname.lastname@example.org or Nicolle Wahl, U of T public affairs, 416-978-6974, email@example.com

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
