 Greetings to all of you fellow scholars out there. This is two-minute papers where I explain awesome research works a couple minutes at a time. You know, I wish someone explained to me in simple terms what's going on in genetics, biology and just about every field of scientific research. There are tons of wonderful works coming every day that we don't know about. And I'm trying my best here to bring it to you the simplest way I possibly can. So you know, researchers are people, and physics research at the Hadron Collider basically means that people smash atoms together. Well computer graphics people also like to have some fun and write simulation programs to smash together a variety of objects in slow motion. However, even though most of these simulations look pretty good, they are physically not correct as many effects are neglected, such as simulating plasticity, bending stiffness, stretching energies and many others. And unfortunately, these are too expensive to compute in high resolution. Unless you have some tricks up the sleeve. Researchers at UC Berkeley have managed to correct this nut by creating an algorithm that uses more computational resources only around regions where cracks are likely to happen. This new technique enables the simulation of tearing for a variety of materials like cork, foils, metals, vinyl, and it also yields physically correct results for glass. Here's an example of a beaten up rubber sheet from their simulation program compared to a real world photograph. It's really awesome that you can do something on your computer in a virtual world that has something to do with reality. It is impossible to get used to this feeling. It's so amazing. And what's even better since it is really difficult to know in advance how the cracks would exactly look like. They have also enhanced the direct ability of the simulation, so artists could change things up a bit to achieve a desired artistic effect. In this example, they have managed to avoid tearing a duck in two by weakening the paths around them. Bravo!
