THE warmongering orcs depicted in the “Lord of the Rings” trilogy are evil, unpleasant creatures that leave death and destruction in their wake. But if you find yourself in a burning building a few years from now, they might just save your life. That is because the technology used to make hordes of these menacing, computer-generated monsters move convincingly on screen turns out to be just what is needed to predict how crowds of humans move around inside buildings. Engineers and architects hope that they will be able to improve building safety by modelling how people behave in the event of a fire.
