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

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
Breakthrough provides a new concept of the design of molecular motors, sensors and electricity generators at nanoscale

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
