Thirza Ember introduced the Hypergrid Safari in a talk on 10th February 2017 at the OpenSimulator Community Conference 2017 (OSCC17)…

Then later that day, the OpenSimulator Community Conference 2017 Hypergrid Safari included five locations on a number of OpenSim grids …

One of which was our OSGrid RGU Oil Rig region… for more details see this blog post.

Vue is a virtual educational and research institute bringing together all those interested in the use of virtual worlds for teaching, research and outreach related to the University of Edinburgh.

Second Life is a virtual worlds platform provided by Linden Lab in California. The Vue regions in Second Life have been available for over 10 years since 28th May 2007. A timeline of events is available at http://vue.ed.ac.uk/… and over the years we have arranged between us a variety of funding for the shared areas from Development & Alumni, Informatics, IS and the Vet School. Having maintained “Vue” as a core region now for over 10 years the usage now does not justify continued funding which even at educational rates costs $1,770 a year for a full region and $750 a year for one of our lower capacity regions.

Vue Regions on OpenSimulator – Openvue

It is worth noting that the whole original 9 region Vue mini-continent as it appeared at its maximum extent in Second Life with some enhanced areas is essentially replicated on an OpenSimulator grid.. in fact on several such grids. One hosted on servers in Informatics… called Openvue… and another on the “OSGrid” openly accessible free to use test grid. These “open” versions of the Vue virtual world facilities have been available since September 2007, A timeline of events is available at http://vue.ed.ac.uk/openvue/… so also for over 10 years now. They provide many of the facilities available in Second Life, including the same type of voice services used in Second Life provided free due to the support of non-profit and educational establishments by Vivox.

Visit Openvue by getting a (free) avatar on OSGrid at http://osgrid.org and then travel via the “HyperGrid” to hop://virtual.aiai.ed.ac.uk:8002/Openvue/128/128/20 (copy that “hop” into the Firestorm Viewer location bar or find the region on the Map).

Local avatars on Openvue are only necessary for builders and owners of regions. Contact Austin Tate if you are a member of the University of Edinburgh and feel that is useful to your projects or work.

How to Continue to Use a (Temporary) Facility on Second Life

Second Life continues to be available, and it is still possible top create and use a freely available avatar to visit facilities in Second Life. It is just the Vue paid-for regions we are no longer maintaining.

Sandbox regions in Second Life are available to test building and can act as a facility where a temporary facility can be rezzed.. such as a copy of “The Venue@Vue” as used for virtual graduations, MOOC class meetings, etc. As a suggestion try “Sandbox Exemplar” first to establish it as a first preference for Vue related meetings on such a Sandbox… but there are lots of other sandboxes. You can find them by typing “sandbox” as a region search term into the Second Life viewer Map tool.

Vue Regional Planning Authority (VRPA)

I would like to thanks the present and past members of the rather grandly named “Vue Regional Planning Authority” (VRPA)* which is the people from across the University of Edinburgh who raised funds for the Second Life Vue regions an were involved in the design and creation of the facilities. the group continue to be involved in explorations of other virtual world platforms in their own Schools, groups and across the University for the potential benefit of others.

Vue Experiments with other virtual Worlds Platforms

Even before Second Life began to be used across the University, groups in Business Studies, Education and Artificial Intelligence/Informatics had been exploring virtual worlds platforms for a range of educational and research project uses. Platforms (now long gone) such as “There” and commercial virtual world simulators such as “Forterra” had been in use, and Second Life itself had been used even in its very earliest incarnation. When we began using Second Life for Vue purposes we could not have imagined the platform would remain stable for such a long period (over a decade and it is still available). We envisaged moving onto new platforms as they arose and experiments have taken place with quite a lot of potential platforms, not all of which made it to full open public release. A number of these experiments are documented in my earlier blog posts.

Some current platforms under investigation include:

• OpenSimulator
• Sansar
• Sinespace

In preparation for the presentation on OAR Converterpresentation at the Open Simulator Community Conference 2017 a speaker preparation event was held on 11th November 2017 on the Conference OpenSim Grid…

Each presentation is also allocated an Expo Booth on OSCC Expo Zone 3… hop://cc.opensimulator.org:8002/OSCC Expo Zone 3/101/58/26

Richard Bartle, virtual world and MUD pioneer, spoke at “The Delphi Talks” in the Sinespace event plaza on 26th October 2017.

On this test, my online virtual world avatar personality Ai Austin appears to be mostly “Explorer” which sounds just about right!

The Bartle Test of Gamer Psychology

You are 100% Explorer

What Bartle says:

♠ Explorers delight in having the game expose its internal machinations to them. They try progressively esoteric actions in wild, out-of-the-way places, looking for interesting features (ie. bugs) and figuring out how things work. Scoring points may be necessary to enter some next phase of exploration, but it’s tedious, and anyone with half a brain can do it. Killing is quicker, and might be a constructive exercise in its own right, but it causes too much hassle in the long run if the deceased return to seek retribution. Socialising can be informative as a source of new ideas to try out, but most of what people say is irrelevant or old hat. The real fun comes only from discovery, and making the most complete set of maps in existence.

You are also:

• 53% Socialiser
• 40% Achiever
• 7% Killer

This result may be abbreviated as ESAK

The Virtual University of Edinburgh regions as they appeared in Second Life at their maximum extent and as they are replicated on the OpenSimuator-based Openvue grid has been converted via the OAR Converter into Unity3D and then provided into the Sinespace virtual world platform.

Vue – Original OpenSim Region Map

Vue – Unity Editor

OAR Converter can take an OpenSimulator Archive (OAR) and from it create textures, meshes and terrain suitable to import into a Unity scene. The converter has been created by Fumikazu Iseki (Avatar: @Fumi.Hax – @fumi_hax) and his colleagues at the Network Systems Laboratory of TUIS in Japan with support from Austin Tate at the University of Edinburgh.

• OAR Converer converts from OpenSimulator Archive (OAR) to Collada files for use in Unity3D.
• This software was developed by Fumi Iseki, Austin Tate, Daichi Mizumaki and Kohe Suzuki

OAR Converter can run on Linux and Windows and source code is available. Full instructions for compiling and using the source code version on these platforms is available via the TUIS Wiki OAR Converter Page. For convenience a version with Windows UI is also available as a ready to run package.

Quick Start Instructions for OAR Converter with Windows UI

OARConvWin is OARConv with Windows UI. OARConvWin converts OAR file of OpenSim to Collada (dae) files for Unity3D.

Download the OAR Converter for Windows latest version from http://www.nsl.tuis.ac.jp/xoops/modules/xpwiki/?OARConvWin&ml_lang=en [<a href="http://www.aiai.ed.ac.uk/~ai/unity/oarconv/"Local Copy]. Latest Version at the time of this blog post in September 2017 is v1.0.6 (at 2016/5/11) which is based on oarconv-1.4.4

For straightforward conversions, simply follow these steps:

Import to Unity3D

You could follow the video instructions in this YouTube video by Fumikazu Iseki.

Project Base for OAR Converter Projects

Once you have successfully tried a conversion and understand the elements, you may wish to create a base for any future OAR conversion… which can include all the steps except for the drag and drop in of the actual DAE converted content. Do this yourself to incorporate the very latest OAR Converter content, scripts and Unity assets. You can if you wish save this as a “unitypackage” to incorporate into future Unity projects.

But, for convenience, a Unity 5 base “unitypackage” has been created which includes the required Editor/SelectOARShader.cs, the water layers and the Unity 5 Standard Assets “Ethan” character with simple movement and attached camera. An alternative with the Blender open source Sintel movie character and attached camera setup as indicated in the OARConv YouTube video is also provided at…

http://www.aiai.ed.ac.uk/~ai/unity/oarconv/

Make a copy of the base project you created or a new unity project, import the chosen unitypackage as a base, and then drag the OAR Converter produced “DAE” directory into the Unity Project Assets area, add the DAE folder assets and those in the DAE/Phantoms folder to the hierarchical view panel. Adjust the position of the chosen character and attached camera to suit the region, save the project, save the scene, and you should be good to go.

The RGU Oil Rig 3D model and virtual world environment in OpenSimulator create by the team involving Jo-Anne Tait and Colin Hetherington at Robert Gordon University (RGU) Oil & Gas centre in Aberdeen Scotland has been ported to Unity3D via the OpenSimulator OAR Converter Tool and provided in the Sinespace virtual world platform. Recently the region has been augmented by wave effects, sea wash around the oil rig legs, sounds sources, lighting and the replacement of the active information “i” signs for training purposes.

Now a night time version has been provided. Scripts to provide a realistic day or night skybox provided by Adam Frisby at Sine Wave and a changing day/night cycle have been used for experimentation. But the initial “Oil Rig at Night” is a dark late at night fixed time scene.

Oren Etzioni at the Allen Institute for Artificial Intelligence has requested feedback on the following NY Times OpEd:

https://www.nytimes.com/2017/09/01/opinion/artificial-intelligence-regulations-rules.html

I provided these notes to Oren on 8th September 2017:

I think its good to have a wide ranging discussion on these matters and to involve the general public. Scare stories could lead to the many potential benefits of AI being lost if there is a negative reaction to the threat that systems can pose… much like happened with GM crops in Europe.

I am not sure that talking of “human operator” is quite the right model. I see future AI systems and robots as “agents” and think the “agency” model is a useful one to include when talking of future AI and robotic/autonomous systems. I think the notion that responsibility lies with the “deployment” or “authorisation” of the agent could help some of the discussion. The idea that such agents are subject to the same laws and regulations and treaties as any other human agent is a good one, and one you cover. Of course that varies by region, and in some lawless or less constrained “off shore” (future “off world”) locations such constraints could be lessened to the detriment of others. So introducing a chain back to those organisations, companies, or individuals who “deploy” or “authorise” the agent may be useful.

Remember, as I am sure you are very aware, that Isaac Asimov’s stories were a warning that the defined three laws could not anticipate all contexts.

My own main concern is the concentration of technology and robotic systems in the hands of a few oligarchs and global companies as systems and devices replace workers. The lack of a social and cooperative approach to this worldwide, and competition for one country or one company to be the “winner takes all” could lead to social unrest and very serious issues. So I am glad to see folks like Bill Gates and others raising issues of taxation on systems and robots in just the same way that there are taxes on workers to pay for the social infrastructure of regions, countries and the world.

Dueling Dragons (US spelling) is a two track “duelling” (UK English) B&M suspended roller coaster at Islands of Adventure in Universal Studios Orlando. The ride is themed as two dragons… Chinese Fireball (Fire) and the other Hungarian Horntail (Ice).It was opened on 28th May 1999 and was converted to become Duelling Challenge in 2010. After some accidents related to injury cause by loose articles, the coaster ran without the synchronisation of the trains from 2011 until the coaster closed on 4th September 2017.

The roller coaster can still be experienced in virtual reality via the NoLimits2 Roller Coaster Simulator.

Dueling Dragons by duduchianca

This version of Dueling Dragons has been modelled by “duduchianca”. He made the twin coasters by modelling one continuous loop which switches station sides half way through. A few issues with trains being allocated to track sections or “blocks” and hitting one another needs to be fixed. The simple fix is to change the number of trains from 6 on track to 2 in the editor… then you can ride “ice” and “fire” alternately without any stops.

Some Observations from sinespace Interactions

1. Chat tool has some issues… scroll bar seems not to work when you have more tabs than the current size window allows. Hide button largely covers the last entry unless you are VERY careful with mouse to avoid it.
2. It would be good to show your OWN avatar labels (maybe on by default even if they can be hidden) so you know what shows to others.
3. Yellow names show for sinewave folks(?). Suggest friends are coloured (say green or blue)… so you know who is a friend of not from before.

A new Sinespace event plaza is being created… at “The Delphi Talks” region. See http://delphitalks.com

To celebrate the 15th September 2017 end of the Cassini Mission to Saturn, I have placed a 3D model of Cassini to realistic scale on the Space City area in our OpenSim grid. This uses one of the freely available 3D models from NASA.

Avatar name labels are not yet included in Sansar. They are useful as a means to recognise others and initiate social communication with them. Soe users have taken to creating an avatar attachment with their avatar name as a label. A 3d text model can be created, exported as FBX and uploaded in Sansar’s “My Looks” as an avatar “Attachment”.

The 3D model needs to be scaled appropriately. I used a 1m X 1m x1m block as a guide. Positioned the 3D extruded text at a little over 2m high and set its original to the 0,0,0 point, so when attached to the avatar it would sit over its head.
