The project of virtually interpreting a simulation on the scope and scale of Hadrian’s Villa was a daunting one – engaging layers of scholarly, technical and pedagogical challenges. The technical challenges were many – foremost to leverage the game engine of Unity 3D to become an effective multi-user avatar-based virtual world. An important factor was to create an environment that was straightforward and accessible via standard web browsers on both Mac and Windows and selected Unity 3D as the starting point for developing the platorm. We required specific back-end administration tools to handle the accounts and server side aspects of the project – for this we relied on Smart Fox Server as it manages Unity 3D quite well. Our team took an approach that bridged and integrated disparate technologies, creating a robust virtual world platform to immersively augment both instructional and PBL processes. VW features available to the learning community included text based communication, a live map showing current visitor positions, map based teleportation, managed voice channel, user selected avatar gestures, online users, paradata, photographs of the extant site, plan views, and integrated web links.
