This project demonstrates a prototype of a simple 3D objects simulation coded using Visual C++ Version 6 and OpenGL on Windows 98 environment. The purpose of this project is to design and implement a framework of 3D objects using object-oriented modeling and design methodology; simulate behavior of 3D objects and show a virtual world of objects. This report introduces a theoretical basis for the project and presents the implementation of 3D objects simulation. Finally, the simulation results and future work are presented.
