Abstract

A computer implemented method and apparatus for floating object transitions. In one embodiment, tracking data identifying a location of an avatar in relation to a range of an object in a virtual universe is received. The range comprises a viewable field. In response to the tracking data indicating an occurrence of a trigger condition, a set of flotation rules associated with the trigger condition is identified. An optimal location and orientation of the object is identified for each flotation action in a set of flotation actions associated with the set of flotation rules. The set of flotation actions are initiated to float the object above a surface. The object changes the location and orientation of the object in accordance with the set of flotation actions associated with the set of flotation rules.
