Web-based e-learning in 3D large scale distributed interactive simulations using HLA/RTI

In this paper, we investigate the integration of HLA/RTI with VRML/X3D in order to provide a training facility that can be accessed through a traditional web browser. We apply our proposed architecture on a test bed that consists of a cancer treatment scenario within a 3D virtual Radioloy Department. We have incorporated the High Level Architecture HLA standard as an important corner stone in allowing the e-learning environment to be distributed and interactive. Combining Virtual Reality concepts with the real pivots of HLA/RTI can create a very strong foundation for such a valuable and required class of applications by utilizing all reliable technologies to make it as flexible as possible. We have ensured that any foreseen future optimizations could be incorporated easily without any overhead
