A computer implemented method, apparatus, and computer program product for object based avatar tracking. In one embodiment, a range for an object in a virtual universe is identified. The range comprises a viewable field of the object. Avatars in the viewable field of the object are capable of viewing the object. Avatars outside the viewable field of the object are incapable of viewing the object. In response to an avatar coming within the range of the object, an object avatar rendering table is queried for a session associated with the avatar unique identifier and the object unique identifier. The object avatar rendering table comprises a unique identifier of a set of selected objects and unique identifiers for each avatar in a range of a selected object in the set of selected objects. An object initiation process associated with the object is triggered.
