OpenSim: an educator’s perspective:

OpenSim : an educator’s perspective Peter Miller University of Liverpool Graham Mills BioZone NWG

OpenSim is...:

OpenSim is... Not a virtual world but a platform supporting standalone regions multi-region grids optionally connected by Hypergrid Both familiar (SL®-like) and novel; extensible Open source: more affordable, more control Less content, fewer sims and users than SL Voice, physics, lag, stability, alpha, IPR issues But...

How it works:

How it works Client/viewer, e.g. Imprudence ( Kokua ) Server running OpenSim (OS) simulator + database http://www.multiurl.com/l/5O8 Client Server Region/ sim Database

Regions can be organised as grids:

Regions can be organised as grids OS 0.6.9 OS 0.7.0.2 OS 0.7.1    73 listed grids (34 shown, 56 HG-enabled) 14K regions (SL: 31K) 21K users/month* (SL: 1M Oct’10) *inc non-HG grids Hypergrid Business: March 2011 Lower Middle Upper i6 http://www.multiurl.com/l/5O5 Dec 2010 Edu Map: Pam Broviak , GovGrid

Clients include...:

Clients include... Based on SL version 1.23 Imprudence Astra* (OS import/export) [Stored Inventory] SL Viewer 2 (web, mesh) Web (Unity3D on-the-fly) BuiltBuyMe * NB IP issues, esp moving content from SL * Not on SL approved TPV list, [ ] no personal experience BuiltBuyMe web viewer http://www.multiurl.com/l/5Ob

OpenSim comes in many flavours:

OpenSim comes in many flavours Platforms Self-hosted ( e.g. Diva Distro ; HD or USB) Hosted (as per SL) Self-hosted, grid-attached, e.g. OSgrid , NWG Hosting services SimHost , Dreamland Metaverse , etc Kitely (on-demand/cloud-based, Fb-reg ) More via Hypergrid Business website Educational grids/federations: “beyond Hyperica ” Immersive Education Grid (IEI) NZVWgrid UK: ViEWS , OSEG, UK Virtual Grid for Learning ( Daden ) OSgrid Ener Hax http://www.multiurl.com/l/5RJ

The Hypergrid: Where do you want to go today?:

How to Hypergrid:

How to Hypergrid http://www.multiurl.com/l/5RH Sim on hgurl.com? Chat search term & touch Find address, e.g. Hyperica Within 4096 regions? Chat address Find way-station Click link in chat history Yes Yes No No Success? No Success? Sim closed? tp issues? No Sims HG-enabled? Also: Map search if within 4096 regions Direct registration, e.g. if different HG versions Yes Try other services No Yes secondlife ://

But: Lag can be an issue:

But: Lag can be an issue Interactivity via marker overlay prims rather than scripting original prims

Intel stress test: Scaling is possible:

Intel stress test: Scaling is possible 655 avatars on ScienceSim cloud-based megaregion Distributed services Scale hardware On-demand, e.g. via Kitely Each map dot is an avatar (most are bots)

Personal small group use:

Personal small group use 4 GB hosted quad-core standalone, 10 Mbit /s bandwidth Groups of 20, 10 and 1; large textures, heavily scripted Configured to 4 regions Outcome Class functional, no server crashes A few avatars slow to rez but still operable Lag varied; due to scripts or time of day (local bandwidth) Future: optimise, e.g. opensim.ini to reduce rate of updating NWG Events on dedicated cores with 20-25 avatars, light scripting Shared core sim supported 3 students building, light scripting Zephyr, NWG Lolly iFrog et al .

Hey, where can we get content?:

Hey, where can we get content? IP issues  closed commercial grids, e.g. Inworldz Many inworld freebie stores Emporium Scooter, jokaydiaGRID Freebie shops Crackou Island, NWG NewVCE NWG Austin Tate

OpenSim: ready for the big time?:

OpenSim : ready for the big time? In my opinion, just about but would be helped by ... Guidance on platform choice/transition Simplified hosting plus info on scaling/stress testing Better sim /class management tools Edu /subject-specific OARs, IARs, HG directory/search Sharing/experiences VWER, JISCMAIL VW listserv, UK (Edinburgh, Glasgow Caledonian, Leeds Met, Bromley College...), University System of Ohio...
