Virtual game characters can leap, roll and climb so realistically that simply watching them could seemingly exhaust a player. Generating the precise instructions that govern such characters in increasingly complex environments is also quite labor intensive and, unlike a game, downright tedious. Scientists at Disney Research, however, have developed an automated approach to generating life-like character motions in interactive environments, helping game designers by both easing their workload and by providing instant feedback on how characters will perform in 3-D space.
