OpenSim: an educator's perspective

2,351 views

Published on

We were pleased to welcome Dr Peter Miller (University of Liverpool) to the Centre to conduct a seminar relating to virtual worlds and the open source platform OpenSim. This talk looked at the benefits and current limitations of the platform. It outlined ways in which OpenSim can be deployed and showed some of the education-oriented and more generic content already available or under development. Finally, the potential role of the Hypergrid, the system for linking OpenSim regions, was considered in terms of establishing educational communities and disseminating good practice.

OpenSim: an educator's perspective

  1. 1. OpenSim: an educator’s perspective<br />Peter Miller<br />University of Liverpool<br />BioZone<br />NWG<br />Graham Mills<br />
  2. 2. OpenSim is...<br />Not a virtual world but a platform supporting<br />standalone regions (“sims”)<br />multi-region grids <br />optionally connected by Hypergrid (HG)<br />Both familiar (Second Life®-like) & novel, e.g. extensible<br />Open source: more affordable, more control<br />
  3. 3. But...<br />Less content, fewer sims and users than SL<br />Issues with<br />Voice<br />Physics<br />Lag<br />Client and server stability<br />IPR<br />
  4. 4. OpenSim(ulator): a selective history<br />2007<br />SL Viewer open-sourced<br />OpenSim project starts; OSGrid founded<br />2008<br />New World Grid & ReactionGrid established<br />First avatar “jump” between OSGrid and SL<br />2009<br />Hypergrid, Diva Distro<br />2010<br />End of SL education discount; interoperability work stops<br />Aurora fork of OpenSim<br />2011<br />Kitely (OpenSim-on-demand)<br />Mesh and interactive web pages<br />Overte Foundation established<br />
  5. 5. How it works<br />Database<br />Server<br />http://www.multiurl.com/l/5O8<br />Region/sim<br />Client<br />Client/viewer, e.g. Imprudence (Kokua)<br />Server running OpenSim (OS) simulator + database<br />
  6. 6. Regions can be organised as grids<br /><br /><br /><br />i6<br />Dec 2010<br />Upper<br />VWER Grid<br />Kitely<br />Middle<br />73 listed grids (34 shown, 56 HG-enabled)<br />14K regions (SL: 31K)<br />21K users/month* (SL: 1M Oct’10)<br />*inc non-HG grids <br />Hypergrid Business: March 2011<br />Edu<br />Hypergrid: Lower<br />OS 0.6.9<br />OS 0.7.1<br />OS 0.7.0.2<br />Map: Pam Broviak, GovGrid<br />http://www.multiurl.com/l/5O5<br />
