System Design for a Shared Virtual Environment Supporting User-Generated Content and Time Navigation

We present an overview of the software architecture for a shared virtual environment that supports both user-generated content and time navigation. The novel combination of these features into a shared virtual environment necessitates fundamental augmentation to established techniques for building such software systems. A survey of related work describes how some of these ideas are present in existing projects. Our software architecture is based on a foundation of object-oriented system analysis and design patterns. We present our current status and outline the directions for future design that must be completed prior to prototype implementation.
