Computer-generated graphics for video games have had quite a few challenges thrown at them over the years. Smooth surfaces have gotten pretty darn good, but things like hair, fur, and cloth have been much more difficult to re-create in a realistic fashion. Researchers at Carnegie Mellon University and the University of California at Berkeley, pressed some computers into six months worth of service, all in the name of creating better digital cloth.
It took 4,554 CPU hours to generate 33 gigabytes of data aimed at figuring out the many ways a piece of cloth can move. This research could end up boosting the quality of things like wizard's robes and superhero capes blowing in the wind in video games. The paper that outlines the results is titled "Near-exhaustive Precomputation of Secondary Cloth Effects."… Read more
