1. A method for modifying objects in a virtual universe, the method comprising the steps of: a computer including in the virtual universe a viewable field, a detection area that is adjacent to the viewable field, and an outside area that is outside the viewable field and the detection area, wherein each avatar in a set of avatars is incapable of viewing the objects while the avatar is within either the detection area or the outside area; the computer, in response to an entrance of a first particular avatar of the set of avatars into the detection area, preparing to display, without displaying, to the first particular avatar of the set of avatars one of the objects by buffering content associated with the one of the objects; the computer detecting a presence of the set of avatars within the viewable field of the one of the objects; the computer determining a real world identity of each user in a set of users that controls an avatar in the set of avatars; the computer receiving user information that is associated with the real world identity of each user in the set of users; the computer assigning, for each avatar in the set of avatars, a priority to the avatar in the set of avatars based on the one of the objects and on the user information that is associated with the real world identity of the user in the set of users that controls the avatar in the set of avatars; the computer creating a temporary and dynamic rule to control modification of the one of the objects based on the priority assigned to each avatar in the set of avatars; the computer modifying the one of the objects to have a first visibility to a second particular avatar in the set of avatars and to have a second visibility to a third particular avatar in the set of avatars in accordance with the temporary and dynamic rule wherein the first visibility is different from the second visibility; the computer initiating implementation of a set of geometric and texture modifications for dynamically modifying the one of the objects in accordance with the temporary and dynamic rule; the computer determining that a particular one of the objects is adjacent to an obstructing one of the objects; and responsive to determining that the particular one of the objects is adjacent to the obstructing one of the objects, the computer setting a focal point of the viewable field at a location that is a different location than a location of the particular one of the objects.
