Object based avatar tracking

A computer program product comprising:

• one or more computer-readable tangible storage devices;
• program instructions, stored on at least one of the one or more storage devices, to identify a range for an object in a virtual universe, wherein the range comprises a viewable field of the object, wherein avatars within the viewable field of the object are capable of viewing the object, and wherein avatars outside the viewable field of the object are incapable of viewing the object;
• program instructions, stored on at least one of the one or more storage devices, to query an object avatar rendering table for a session associated with an avatar unique identifier and an object unique identifier in response to an avatar coming within the range of the object, wherein the object avatar rendering table comprises a set of object unique identifiers for a set of selected objects and an avatar unique identifier for each avatar within a range of a selected object in the set of selected objects;
• program instructions, stored on at least one of the one or more storage devices, to trigger an object initiation process associated with the object;
• and
• program instructions, stored on at least one of the one or more storage devices, to, responsive to a determination that the object is adjacent to an obstructing object, set a focal point of the viewable field at a location that is a different location than a location of the object.

A virtual universe grid computing system for object based avatar tracking, the system comprising:

• one or more processors, one or more computer-readable memories and one or more computer-readable tangible storage devices;
• program instructions, stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, to identify a range for an object in a virtual universe, wherein the range comprises a viewable field of the object, wherein avatars within the viewable field of the object are capable of viewing the object, and wherein avatars outside the viewable field of the object are incapable of viewing the object;
• program instructions, stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, to generate an object avatar rendering table, wherein the object avatar rendering table comprises a set of object unique identifiers for a set of selected objects, and an avatar unique identifier for each avatar in a range of a selected object in the set of selected objects;
• program instructions, stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, to detect an avatar coming within the range of the object;
• program instructions, stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, to query the object avatar rendering table for a session associated with an avatar unique identifier for the avatar coming within range of the object and an object unique identifier for the object;
• program instructions, stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, to trigger an object initiation process for the object;
• and
• program instructions, stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, to, responsive to a determination that the object is adjacent to an obstructing object, set a focal point of the viewable field at a location that is a different location than a location of the object.
