This paper introduces object structure and communication framework that allow simulated objects to be able to determine its own behaviors. In contrast with conventional simulation system in which every object reaction process is fully controlled by the simulation function, in this model, simulation function is responsible only for event, timing, and consistency controls. As a result, objects are highly independent from the system. and thus can be distributed through computer networks, or applied in parallel processing. It also enables the simulation of very complex scenarios such as when an object is partitioned into atomic elements, also when there is a large number of objects participate in the simulation. Moreover, as the simulation is based ideally on the natural mechanism, it therefore, yields realistic results. Discussions in this paper covers : object communication model, sampling time mechanism, object structure, and simulation distribution. Object communication model includes what object communication is, also when and how it works. The communication may occur between objects and the system, among objects, or even inside the objects. Sampling time mechanism issues include how object collisions are detected; also how event-driven sampling time is calculated and adjusted. The concept of timing synchronization is also discussed. Concerning object structure, the definitions of node and link, the relationship between nodes and links, and how node-link wireframe meshes form an object, in both 2D and 3D, are discussed. Also, how objects are deformed, and how events are propagated through the structure. Finally, how this framework can be adapted to the distributed environment is described.
