Web-based applications for academic education facilitate, usually, exchange of multimedia files, while design-oriented domains such as architectural and urban design require additional support in collaborative real-time drafting and modeling. In this context, multi-user interactive interfaces employing game engines as well as Virtual Reality (VR) environments offer a framework within which web-based applications for virtual laboratories have been in the last decade successfully developed and tested within Hyperbody at Delft University of Technology (DUT).
