Abstract
An animation system and method for defining and using one or more groups of objects in an animation allows an animator to define at least one membership rule that determines membership of an object in a group. Parameters such as properties, operators, effects, constraints, expressions and the like can be defined for the groups and can be inherited by each member of the group. A membership rule is evaluated at defined intervals to determine which objects in a scene satisfy the rule. The objects that satisfy the rule are included in the group defined by the membership rule. At least one parameter, selected by the animator for application to the group, is then inherited by each member of the group.
