Steam evaporating. A shirt creasing. Hair mussed up. Recreating these small,deceivingly complex details of everyday reality is important forconstructing virtual worlds that are faithful to perceptions of the realworld. A lot of math, physics, and computer theory are inherent in thischallenge, but so is poetry, says Adrien Treuille, assistant professor ofcomputer science and robotics. Maybe even some magic is involved, too. Treuille is profiled inthe latest issue of Carnegie Mellon Today.
