Organizing ready-made virtual objects for virtual environments

In the world of simulation, Virtual reality (VR) software allows users to visualize, manipulate and interact with computers and complex data. VR has been utilized in applications such as architecture, medicine, advertisement, business, entertainment, and education. Developing VR environments is costly and expensive. Highly-technical persons are needed to create the virtual objects from scratch. Once a virtual system is created, managing and modifying it creates further problems. There is a need for non-technical users to be able to create and modify their own virtual environments. This paper discusses a systematic and dynamic framework to manage virtual objects in virtual environment. It is called Virtual Reality System-Hierarchy Embedded Virtual Objects (VRS-HEVO). It comprises of two components; the Stand- Alone VRS-HEVO and the Distributed VRS-HEVO. To implement the framework, Java 3D and Java Swing have been used. A usability study on the performance of the framework has been carried out. Users have perceived it as an easy tool to use, especially for an environment in education.
