Despite the fact that there being a large literature on simulation, there is as yet no generic paradigm or architecture to develop a three-dimensional (3-D) simulator which depends on autonomous intelligent objects. This has motivated us to introduce a 3-D simulation system based on intelligent objects for Physics Experimentation. We formulated the system’s components as an object-orientation model. So, the entities in every experiment’s work cell are modeled by characterizing their properties and functions into classes and objects of the system hierarchy. Intelligent objects are realized by developing a knowledge base (KB) that captures a set of rules/algorithms that operate on 3-D objects. Rules fall into two categories: action and property rules. In the simulation layer, the student is allowed, by using the virtual system, to stroll throughout the Physics laboratory in light of a walking model. Student gets to a simulation region to do an experiment through the detection of mathematical collision. From software engineering perspective, the proposed system facilitates the Physics experiment through making the specification of its applicable parts more modular and reusable. Moreover, a major pedagogical objective is achieved by permitting the student tuning parameters, fixing component of a device then visualizing outputs. This provides student well interpretation by viewing how distinct parameters affect the outcomes of the experiment. With the objective of student performance measuring, we utilized an exploratory group relying upon pre- and post-testing. The application results demonstrate that the simulator contributes positively to student performance in regard to practical Physics.

Abstract Based on the Object-Oriented Simulation System for 3-D Packing developed by Dai & Cha (1993a), this paper presents an effective heuristic algorithm using the Octree Data Structure for the three-dimensional packing problems of irregular components. It also describes in detail the Tri-Ring Method which is designed for the topology identification of the octree’s construction. For those problems where the total volume of packed items is smaller than that of container, the results of the theoretical analysis and numerical experiments show that the heuristic is excellent both in packing quality and calculation cost. For those problems where the total volume of packed items is larger than that of container, a variant of this method is expected to be also quite effective. The packing of arbitrarily shaped objects is achieved by packing their octrees generated from their EXTENTS or BOUNDING BOXES.
