Description: To study and predict boundary effects, researchers have struggled to accurately capture erratic, complicated behavior in a computer model. In recent years two schemes for calculating what happens at rapidly evolving interfaces have provided new insights into a variety of physical processes important in technologies such as semiconductor manufacturing and ink-jet printing. "By suitably writing the equations for a propagating interface, one can find a way of borrowing numerical techniques from computational fluid mechanics to solve these equations of motion," says mathematician James A. Sethian. Researchers have now adapted the same techniques to detect edges in scanned medical images, find optimal paths for robots negotiating obstacle-strewn courses, and create special effects for movies...
