GDPR for Vue

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.

The Vue web site is at http://vue.ed.ac.uk. More information on the use of virtual worlds in the University of Edinburgh is available at http://blog.inf.ed.ac.uk/atate/virtual-worlds-technology-for-university-of-edinburgh/

The OpenSimulator-based Openvue grid has only a few local avatars who have regions and creator roles. Most use is as an openly accessible Hypergrid destination to allow users with avatars on other OpenSimulator grids to visit. All local (creator) users for Openvue have been notified and given contact information for the grid manager (a.tate@ed.ac.uk) if they have any queries or issues. A section has been added to the Openvue Terms of Service (ToS) to give the grid manager contact details and to explain what is logged for any visitor and for how long this is retained.

http://virtual.aiai.ed.ac.uk:8002/wifi/termsofservice.html

The European Union General Data Protection Regulation (GDPR) applies to any system which stores personal data. To allow for diagnostics in the case of technical issues Openvue creates logs which record the avatar name, home grid and viewer IP address for any visitor. These logs are not shared with others and are not kept when the grid software is updated. If you have any concern about such logs and their contents please contact <a.tate@ed.ac.uk>, the grid manager.

vue@ed.ac.uk is a mailing list used to communicate occasionally between those interested in the Virtual University of Edinburgh (Vue). This list is normally internal to members of the University of Edinburgh and members are added manually (by Austin Tate on request) and each message allows for unsubscription. Austin Tate can also handle manual unsubscription for anyone requesting it. The mailing list is moderated for posts and non-member posts are removed before being sent to members to keep the number of posts low and encourage people to stay on the list while it may be useful to them.

Virtual Worlds Technology for University of Edinburgh

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.

This post summarises some of the virtual worlds technology that is in use within the Virtual University of Edinburgh (Vue) community. It is provided as a single post to bring together some of the notes and blog posts for the convenience of the School of Informatics Educational Technology team.

Virtual World Platforms for Vue

  • Second Life – a commercial grid run by Linden Lab in California. Vue regions have been in place since 2007. From 2018 no paid-for regions have been retained but alternative educational spaces are available. See this blog post for advice.
  • OpenSimulator (or OpenSim) – an open source community platform. There are Vue regions on grids run by the open source community for testing and educational uses (OSGrid) and within the University of Edinburgh on servers maintained currently by Austin Tate (Openvue). A suggestion is that you use the FireStorm Viewer which works for both Second life and OpenSim.
  • Sinespace – a new platform with VR headset, desktop and mobile clients. Vue regions are maintained on this platform having been converted from the Second Life/OpenSim content via the OAR Converter tool into the Unity3D development environment for delivery in Sinespace.
  • Other platforms: Vue has used a range of platforms from “There” and “Forterra” some 15 years ago to more recent newer technology platforms such as High Fidelity, Sansar, etc.

Meetups in Virtual Worlds

Meetups can take place in facilities such as The Venue@Vue, the OpenVCE amphitheatre, and various I-Rooms (Virtual Spaces for Intelligent Interaction).

2015-01-15-AIPLAN-003-SL-Meeting-Screen-6

Class meetups, mixed reality workshops and conferences, seminars, etc are run in Second Life, OpenSim and on other platforms…

Virtual Graduations

Graduates (especially those achieving distance education degrees) who cannot attend physical graduations in Edinburgh can in some schools take an active part in the ceremony via participation in a virtual ceremony linked via two way video links to the McEwan hall graduations. See http://vue.ed.ac.uk/graduation.html for more details, sample images and other information.

Educational & Training Simulations and VR

Schools such as business studies, Informatics, Education and the Dick vet have made use of simulations and experimental setups for projects and teaching in Second Life, OpenSim, Sinespace and other platforms.

2014-11-28-OpenSim-Oil-Rig 2014-11-28-OpenSim-Oil-Rig-BOP

Some of these are very effective when used with Virtual Reality (VR) headsets such as the Oculus Rift or Vive.

Virtual Art Galleries, Expo Pavilions and Demonstration Areas

A number of projects linked to museums and art galleries have created facilities to showcase their work in the Vue virtual worlds platforms. Art created by University members has also been displayed in a number of facilities… see for a summary http://blog.inf.ed.ac.uk/atate/vue-virtual-art/. For example the Infromatics Forum InSpace Gallery with artwork related to its construction period and other artwork associates with Informatics and its members, the Forum, and Vue…

An active expo pavilion and underwater gallery showcasing work on monitoring fish off a coral reef in South-East Asia was also created for the EU Fish4Knowledge project…

Orcrist

Orcrist is an elf created sword found during the journey of Thoren Oakenshield, a dwarf, in Middle Earth… and features in the Hobbit movies. I handled the Orcrist prop used for the movie while on a visit to Weta Workshop in Wellington, New Zealand and saw one of the limited edition weapons-grade replicas at the Royal Armouries in Leeds, Yorkshire, UK.

3D Model Import to OpenSim

I made use of a Blender model by VoltaJack_ from Sketchfab which is licenced CC-BY.

Poly reduction and tidy up for OpenSim was done by Fred K. Beckhusen (Ferd Frederix) of Micro Technology Services, Inc. and I did the final texturing, adjustment of scale and wearable positioning and packaging.

The mesh reduction method as described by Fred is as follows.

  1. Starts at 236K triangles – about 10 X the limit. I applied a Decimate Modifier at 0.1 ratio (90% reduce) and it went to about 25K tris. Still over 4 avatars worth of triangles and more than the 21K limit. Did a 10X again (a total of 100X reduction) and it came in at 3,440 tris, looks acceptable, still a lot more than a custom build from scratch, but that what you get when you start with a high poly model.
  2. Then select all the vertexes in Edit mode with ‘a’, and do a Vertex (Ctrl-V)->Remove doubles. This drops extra vertexes.
  3. The other wise thing to always do is Mesh-Cleanup Delete-Loose to get rid of any lines or points. Opensim/Sl hates them ( there are none)
  4. Last one is Mesh->Cleanup->Limited Dissolve. This gets rid of extra dots and lines by collapsing them away.
  5. Added a smooth shader and an edge split modifier to get the blade smooth but with a sharp edge. Adds geometry, but it looks much better.
  6. Final is 3.5k tris, versus 236K. I can get it to 1.5K, but it would need more manual cleanup. I did clean up some few tris the distorted in it.
  7. Separated the end of the sword so you can add a texture.

The Blade normal map was produced using https://shadermap.com/home/

Orcrist in Second Life and OpenSim

For a while my Second Life avatar has had an Orcrist sword purchased from the Second Life Marketplace. This is shown below alongside the new Orcrist in OpenSim.

Sansar Sit

At long last avatars can be made to sit down in Sansar… see this blog post for details. Currently just cross-legged on the ground. Sitting can be initiated using “/sit” typed into local chat tool in desktop mode. A very nice lead in and return to standing animation is used that looks very natural.


The full list of “/emote” commands are given in https://help.sansar.com/hc/en-us/articles/360000286366-Avatar-emotes. You can exit sitting (and other animations that play indefinitely) by using a motion control to move your avatar.

Its not currently possible still to sit on chairs, sofas, vehicles, etc. There is a good discussion in Inara Pey’s blog post on 31-Mar-2018 relating to the technicalities behind this.

Bank of High Fidelity

High Fidelity now has a cryptocurrency “Wallet” in which High Fidelity Coins” can be deposited, paid out and transferred to other avatars. To seed the currency early alpha tester users can obtain a starter amount of coins by visiting the “Bank of High Fidelity” during certain times when a banker is present…

Second Life – Isle of May

The “Isle of May” created by Serene Footman and Jade Koltai is on the “Weed” region in Second Life and can be accessed via this SLurl: https://maps.secondlife.com/secondlife/Weed/100/102/41

Anchored on the Firth of Forth in Scotland, the Isle of May is a magical mix of sea birds (cormorants, guillemot, puffins, etc) and sea animals such as orcas and dolphins. The island is a perfect home to artists and photographers.

The region has wonderful “Windlight” environmental and lighting settings. Off region cliffs, sea stacks and waves created by Antreas Alter of Real Waves make the region appear much larger and more dynamic.


Images captured with the Second Life 360° snapshot project viewer (click on thumbnail to view via Flickr in a suitable browser)…

Serendipity Dyrssen created a nice machinima for a visit to the Isle of May region…

Magic Leap – First Leap

Magic Leap opened its web site for creators on 18th March 2018. This blog post brings together some resources, links and screenshots from a first “leap”…


Following the Magic Leap tutorial for Unity 2018.1.0b8 MLTP1 integration.. and its initial “Hello Cube” example…

And then trying one of my Gerry Anderson test meshes (Supercar).. which leaps in fine…

And, why not, the Space Station and Orion Shuttle from the movie 2001: A Space Odyssey… also checking out a custom virtual room created with the Virtual Room generator (a 12m x 12m x 6m space with no furniture, the maximum the room generator tool allows), Unity object rotation scripts for the objects and eyepoint movement using an Xbox Controller…

Pandora in the Virtual World

I have blogged before about the Pegase region for the Pandora Universe group in Second Life which offers role play based on the “Avatar” film directed by James Cameron and based on Pandora, a moon of Alpha Centauri.

The Pegase area arrival/vendor area offers a number of free na’vi starter avatars, an RDA (scientists) outfit and a flyable ikran.

After visiting the Pandora region at DisneyWorld in February 2018 I revisited the regions as “Ai’tswayon” (Ai wing)and took to the air again on my ikran “Ai’tsyal” (Ai fly).

And with a new (free) golden ikran from the Pegase vendor area … also called “Ai’tsyal”…

I tested a new version of the Linden Lab Second Life 360° snapshot project viewer (version 5.1.2.512774) which now adds the proper metadata to show with 360 degree capabilities in Flickr

Early Drag Racing in UK

This post brings together some early scrapbook material about my involvement and that of my brother Jon with the early development of drag racing in the UK. I was prompted to bring this material together and scan some early press articles on our activities after an enquiry from Jeremy Cookson who runs a web site documenting early drag racing strips in the UK, and he was asking abot Riccall Airfield in North Yorkshire. This was the location of a number of eighth mile sprint and drag racing events run by the British Quarter Mile Association (BQMA).


Jeremy Cookson
Raceway Promotions & Club Liaison
Shakespeare County Raceway @ Long Marston Airfield

I run a Facebook page entitled UK Drag & Sprint Strips That Time Forgot. This is where we document as much as we can about long forgotten airstrips and motor racing circuits other than the established ones like Santa Pod. Recently we have added a profile about Riccall Airfield, Yorkshire where we are trying to piece together event and date information from the days when the certainly forgotten about British Quarter Mile Association ran a few eighth mile events in the late sixties (1969 I think). So, this is when I performed the usual search on Google and came across your blog page and references made to Riccall. In your time I note that you used to be the flag starter as well as Competition Secretary for the BQMA, and I was wondering if you could give me some additional information about these events that we could include in the profile. As you will see from the FB link we have uncovered 3 photos, the club logo and that’s about it. Since I have discovered that the club had its own newsletter called Acceleration. Dave Hoy and Chris Tilney I believe contributed to this publication with cartoons and artwork. Chris in fact is one of our Group Members who used to help out running events for the Newcastle & District Timing Association and Millfield and Tughall Airfields before moving to Felton as the North East Hot Rod Association.

My reply tried to give some information about BQMA…

You came across my blog post which included a short bit on BQMA and the eighth mile strip races we did at Riccall.

http://blog.inf.ed.ac.uk/atate/2014/07/31/de-lacy-motor-club-clubhouse-50th-anniversary-events/

1965-10-03-BDRA-Dragfest-2-Woodvale-TicketMy other club involvement in the mid 1960s through to the mid 1970s was in Drag Racing clubs. Younger brother Jon won a competition in the Eagle Comic and was awarded 1964 “Drag Festival” tickets. I went with Jon and elder brother Morris to see the second visit of the US Drag Racing Team to the UK in October 1965 and saw them in the Drag Fest at RAF Woodvale Airdrome near Southport in Lancashire when the first 200+ m.p.h. finish from a standing start on a quarter mile run on British soil was done by Buddy Cortines. The participants included Don Garlits and Tony Nancy amongst other famous early US drag racers.

Drag-Racing-UK-Clubs BQMA Logo

I was a member of the National Sprint Association (NSA), British Hot Rod Association (BHRA) and British Drag Racing Association (BDRA). I also was involved as competition secretary and flag starter for the British Quarter Mile Association (BQMA) who ran events at Riccall Airdrome in Yorkshire. On one event at Riccall advertised for us by free (some called them “pirate”) Radio 270 we had thousands of people turn up to see the drag racers. I ran a drag bike in some events, and my brother Morris who raced a go-kart also entered at one stage with that.


My scrap book also contains a copy of two short pieces in The King’s School Pontefract Magazine – “The Pomfretian” from 1964 and 1965, and some local events we ran to promote drag racing in the North of Britain… including a Dragster float in the Knottingley Carnival on 3-Jul-1965 and a social evening on 18-Nov-1965.







In late 1965 and early 1966 brought together drag racers in the North for some social events which led to the formation of the BQMA…


I designed the BQMA logo and still have the original artwork in my sketchbook. A run of stickers/decals and a few chrome bumper badges were produced. One is on the wall in the De Lacy Motor Club House at Brotherton in Yorkshire with various motoring memorabilia. Also here is an image of a BQMA membership card… mine from 1967…

There is a posed BQMA group image of a couple of the dragsters and three drag bikes with their crews at Riccall…

I cannot recall how many races we ran. The races were only open to club members by our RAC competition licence… but one specific event went a bit viral when Radio 270 (as In mentioned above) ran a LOT of mentions of it on the radio.

At that time Jon was in touch with Radio 270 off the Yorkshire coast and even went out to the boat that had the transmitter just at the time we did one event. He had met Mr. Proudfoot, a supermarket chain owner in Yorkshire, who was involved with Radio 270 and got invited out there… which led to the coverage on the station and encouraged a LOT of people to come. I recall over 1,000 turned up, but that is from a vague memory! And to comply with our licence to let them in we had to get them to join the BQMA… So for a year we had a BIG membership! They did get their Gestetner produced newsletters, but it was way more work than we expected. Mike Hobman was the general secretary. He died at a very young age I am sorry to say. Our dad, Charles Tate (a local JP) helped us out a LOT and took charge when the car queues backed up at Ricall. Coordinated with the police to make sure there were no obstructions and helped sign folks in at the gate. Sterling job for which I have continued to have fond memories of a busy but excellent day. We met our licence conditions.

Vue Virtual World Artworks


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.

A number of virtual world artworks have been created in the Virtual University of Edinburgh (Vue) virtual world platforms such as Second Life and OpenSimulator. Some are novel pieces of art created collaboratively by members of the University from a number of Schools, others preserve temporary real world art installations which have long since disappeared to preserve their concepts and designs, others honour University members who have won art or photographic competitions with their works.

InSpace Gallery

A model of the InSpace Gallery that sits alongside the Informatics Forum was created initially on the Vue regions in Second Life and ported to the OpenSimulator-based Openvue grid and via the OAR Converter tool to Unity3D and Sinespace.



The Inspace Gallery can be reached via:

Inspace Gallery – Construction Walkway

Informatics Forum InSpace Walkway: On-site Construction Walkway Art, January 2007.
Artists: Richard Spencer, Dan Brown, Kadie Salmo and Richard Brown (Informatics Artist in Residence, 2005-2007).


Images and 3D models related to the construction walkway appear in the virtual world InSpace Gallery.

Paolozzi Turing Prints

The Paolozzi Turing Prints are displayed in the (real world) level 5 boardroom in the Informatics Forum and appear in articles for promotion of the School of Informatics. The designs for the prints appear in the InSpace Gallery on the in the OpenSimulator-based Openvue virtual world grid and in the Vue region on the Sinespace virtual world.

A model of some of Paolozzi’s plaster maquettes used for his sculptures and some stainless steel and bronze sculptures given to the University or on display in the Informatics Forum also appear in the virtual world InSpace Gallery.

Rakhi Kumar – Stairway to the Clouds – Photos

Rakhi Kumar created a number of atmospheric photos of the spiral staircase that sits atop the Informatics Forum. These photographs are on display in the InSpace Gallery.

Photo Competition – Graeme Pow – Penicuik Turner Prize 2008


Graeme Pow – Penicuik Turner Prize 2008: Frosty Wrought Iron Spiral
The winning photograph is on display in the InSpace Gallery.

All Eyes – Collective Art at the Smithsonian American Art Museum’s Luce Foundation Center

Austin Tate (avatar: Ai Austin) contributed an image to an online public collective art venture entitled Ghosts of a Chance which led to an exhibition in 2008 at the Smithsonian American Art Museum’s Luce Foundation Center [Final Report by Georgina Goodlander] [Local Copy]. The mosaic is on display in the virtual world InSpace gallery.


There is a related MSc project done as part of the MSc in e-Learning/Digital Education in 2011-2012 entitled “I, PI, … Eye“.

Supercar Comic

A detailed 3D model created by Mick Imrie and Austin Tate of Gerry Anderson’s Supercar from the children’s puppet TV show of the early 1960s was used by Austin Tate to create accurate outline line art for the Misc!Mayhem Comics Supercar Comic in 2003. One example page is on display in the InSpace Gallery… a dramatic page from issue 0 page 21…

ACE Sculpture

There are many objects placed in the Vue virtual world spaces. Galleries and displays for student projects have been set up annually for some Schools with some of the exhibits being in place for longer periods. One sculpture was created when the Vue regions on Second Life were first set up in 2007 and it has been replicated on later platforms used for Vue including in OpenSimulator and Sinespace. This is at “ACE Sculpture” by James Stewart of Arts, Culture & the Environment. It demonstrated the use of a simple “prim” to build complex shapes using the in-world building and twisting tools, as well as surface texture properties.

Trans – – – ~ Formation – a trans-media virtual environment art installation

A trans-media virtual environment interpretation, created by three artists and one virtual world avatar. It is a formation of modular kinetic objects along with accompanying music and images. It includes a version of a “molecules” robotic kinetic sculpture originally designed by Richard Brown, Artist in Residence in the School of Informatics 2005-2007, for the Informatics Forum. The planned installation was called “Formation” and has been recreated in the virtual world inside the Castle Hill terrain on the Vaults@Vue as part of the art installation. Music was provided by Julian Wagstaff of the School of Music in a piece he suggested called “Treptow“.

More information at http://www.aiai.ed.ac.uk/~ai/trans—~formation.html The installation can be found on the Edinburgh Uplands region on the Openvue grid via:

hop://virtual.aiai.ed.ac.uk:8002/Edinburgh%20Uplands/120/188/33

North Landing – multi-media virtual world installation

A multi-media virtual world installation inspired by dramatic landscape and historical events off Flamborough Head in Yorkshire. It was inspired by the musical by Julian Wagstaff entitled ” “John Paul Jones” and a piece of dramatic music in that entitled “The Battle of Flamborough Head”. Austin Tate also has a close association with the North Landing on Flamborough Head. The piece includes an in-world controller to activate kinetic movement of objects, waves, coloured lighting, atmospheric and particle effects. A visualisation of the music was created using the Sony PlayStation2 music player visualisation to add to object faces.

More information at http://www.aiai.ed.ac.uk/~ai/north-landing.html

Vue Theme & Vue Balloon Tour Machinima

John Clift, composer and at one time Disney executive and producer, as well as a friend of the University of Edinburgh, kindly allowed us to use one of his compositions as the “Vue Theme”. The Vue Theme is used as background music on the Vue facilities in virtual worlds [Vue Theme: John Clift Box 2 Track JC-B2-T08V3 230199.mp3].

It was used for a machinima created by a team from the School of Informatics (Ai Austin, Anwen Munro, Davie Munro & Skye Gears) in 2008 with a balloon ride over the Vue regions and educational facilities in Second Life.

The balloon itself was based on a real life event where a balloon “glow” took place in the University of Edinburgh Old College Quad in January 2006.

Music (Box 2 – JC-B2-T08V3 230199.mp3) used with permission of John Clift

In fact there was an earlier balloon flight over the Old College Quad by James’s Sadler in a hydrogen balloon in 1815. More on his balloon flight is available in an interesting article entitled “Four Fantastic Aeronauts” with lots more images on the Smithsonian Air and Space Museum web site [Sample images used here with their permission].


Real World Public Art Around the University of Edinburgh

There is an extensive and varied collection of public art across the University of Edinburgh… some documented in an article entitled in an article entitled “Thair to Remain”** in the The University of Edinburgh Bulletin Staff Magazine, December 2017.

** The inscription on which the title was based was noted by the Bulletin Editor as corrected to “Thair to Reman”.

Vue -> Openvue


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, Corporate Services, Information Services, Informatics and the Vet School. Having maintained “Vue” as a core region for over 10 years the usage now does not justify continued funding which even at educational rates costs $1,770 a year for our full regions and $750 a year for one of our lower capacity regions.

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

Second Life continues to be available, and it is still possible to 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 the “CNWL” sandbox region provided for public use by the College of North West London 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 Buildings available on Second Life Marketplace

To help people create temporary facilities on Second Life sandboxes or other areas where they are allowed to build, a number of Vue-related buildings and facilities are available (free) from the Second Life Marketplace…

Second Life Marketplace – Ai Austin Store

Vue Mailing List

A moderated e-mail list is maintained for members of the University of Edinburgh interested in virtual worlds for teaching, research and outreach. Contact Austin Tate <a.tate@ed.ac.uk> to be added to the list.

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/128/128/30 (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.

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:

Virtual Graduations

In previous years Virtual Graduations for the School of Education and the Vet School have taken place in mixed reality with distance education students attending in Second Life – usually at “The Venue@Vue” and link up on large screens with the physical graduation in the McEwan Hall. For the 29th November 2017 the virtual graduation ran with pre-recorded videos projected in McEwan Hall and a Collaborate back-channel as provided by our Virtual Learning Environment for distant graduands.
See https://media.ed.ac.uk/media/t/1_3uyjbwjy

Suggestions for a Virtual World Visit for Demonstrations

There are some educators who do use Second Life to demonstrate virtual world capabilities to their students. Since the Vue-specific regions in Second Life are no longer available from December 2017 the following notes may help in planning an alternative.

  1. If you have your class use the Firestorm Viewer rather than the default Linden Lab Second Life viewer you can use one viewer to access either Second Life or alternative OpenSimulator-based Grids. Download from http://www.firestormviewer.org/downloads/
  2. To make use of Second Life have your stdeuns create a (free) avatar at http://secondlife.com and the select a suitable open access region where you can visit and show your students items of potential interest. Look at the Second Life Destination Guide for suggestions. This might be a themed area, an area showing specific architecture or period buildings, an area showing a scientific or nature area, or a sandbox where students will be able to build. An example sandbox is described at http://secondlife.com/destination/educational-sandbox
  3. Where appropriate you might like to try an OpenSimulator-based grid. One suggestion is to have your students create a (free) avatar on OSGrid at http://osgrid.org – a grid provided by the open-source community for testing and open access. Then seek out a region on OSGrid that is appropriate to your educational purpose. Sandbox Plaza is one of several sandbox regions on OSGrid where students can build. There are some Edinburgh/Vue related exemplar regions on OSGrid too, such as Vue-Port and Edinburgh. See below for a replica of the Venue@Edinburgh,
  4. If you do try OpenSimulator e.g. via OSGrid, you might be interested in showing the “Hypergrid” which allows multiple separate grids to be linked so that visitors from one grid can visit another. E.g. an OSGrid avata5 can visit the Openvue grid hosted on Virtual University of Edinburgh servers. Use a suitable “hop” in the address bar in Firestorm to visit other grids … e.g. hop://virtual.aiai.ed.ac.uk:8002/Openvue/128/128/30 and after the visit you can teleport back to OSGrid using the link placed in chat.

The Venue@Edinburgh on Edinburgh Region in OSGrid

Visit with an avatar from any Hypergrid-enabled OpenSimulator-based grid using the address hop://login.osgrid.org/Edinburgh/189/62/24 and then take a look at the clickable destination board to find other educational and experimental locations to visit on OSGrid, Openvue grid and the experimental demonstration “AiLand” grid.

Sinespace – Delphi Talks – Richard Bartle

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



YouTube – Delphi Talks with Dr. Richard Bartle [1:23:50]


You might try the Bartle Test of Gamer Psychology to identify the type of gamer you are on Richard Bartle’s Gamer Types categories…

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

Sinespace – Vue

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 – OpenSim

The original OpenSim “mini-continent” contains 12 256mx256m regions…

Vue – Unity Editor

Effect of using Sinespace OAR Material Cleanup Tool:

  • Before cleanup: Upload=1323.81MB, Windows Build=312MB, WebGL Build=467MB
  • After cleanup: Upload=252.22MB, Windows Build=64MB, WebGL Build=121MB
  • Note: The small changes in number of Materials and Meshes are due to other tidy up actions… the OAR Material Cleanup tool acts to reduce the number of Textures significantly… from 2255 using 682.60MB to 447 using 152.40MB.

Vue – Sinespace


The download size in Sinespace for the Vue regions on various platforms is as follows:

webgl (110mb), win32 (57mb), android (53mb), ios (63mb)

The Vue regions can be visited via the downloadable Windows or Macintosh desktop viewer (for higher quality and more reliable loading of large regions) or reached via WebGL in a suitable web browser (such as Internet Edge, Google Chrome or Mozilla Firefox):

OAR Converter

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

  • OAR Converter from OpenSimulator Archive (OAR) to Collada files for use in Unity3D.
  • Software developed by Fumi Iseki, Austin Tate, Daichi Mizumaki and Kohe Suzuki.

This blog post is provided for convenience and using content from the original TUIS OAR Converter Japenese Web Site which should be considered definitive.

2015-09-04-Unity-OpenSim-OpenVCE-960x598arrow-right-36x1872015-09-04-Unity-OpenVCE-Web-Payer-960x598

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.

OAR Converter with Windows UI – Quick Start

Download the OAR Converter for Windows latest version from http://www.nsl.tuis.ac.jp/xoops/modules/xpwiki/?OARConvWin
[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:

  1. Place your OpenSim OAR file in a suitable directory. Using defaults, the conversions will be placed in separate directories in this same directory with names based on the OAR file name prefixed by OAR_ and DAE_
  2. Run the OAR Converter and using “File” -> “Open OAR File” select the OAR file you wish to convert. This will create a directory called OAR_ with the unpacked contents of the OAR file ready for conversion.
  3. Now select “File” -> “Convert Data” from the OAR Converter File menu. This will create a directory called DAE_ with the converted content in it.
  4. The DAE_ directory created will contain the DAE/Collada objects for the conversion which have colliders (are solid) and one special DAE/Collada object for the terrain (named the same as the OpenSim region name). It will also have sub-directories for all Textures and for the Phantoms (objects with no collider).

Import to Unity3D

You could follow the video instructions in this YouTube video by Fumikazu Iseki. The first part of this video shows the use of the Linux version of the converter, but the part from [2:23] to [6:10] gives an example of importing the converted DAE/Collada folder contents and merging that with a Unity project/scene including adding a Unity Standard Asset water surface. Importing the included “UnityChan” character is shown in the last part of the video.

Import to Unity3D – Quick Start

  1. Ensure you add the contents of “forUnity3D” folder in the OAR Converter distribution into your Unity project, adding Editor/SelectOARShader.cs at least. A slight improvement to one file in this distribution is available… the file in Unity3D/Editor named SelectOARShader.cs can be replaced with a version which fixes materials on bright objects imported to Unity. Replace it with UnitySelectOARShaderBrightFixed.cs [directory for right-click download] [direct link]. Don’t leave both versions in place.
  2. In your Unity project add an empty game object at 0,0,0 and name it the same as your OpenSim region name. Under this add three empty game objects named Solid, Phantom and Terrain also at 0,0,0.
  3. Drag the DAE_ folder in its entirety onto the Unity “Project” (Assets) panel.
  4. Select all the objects in the top level of this directory except the Textures and Phantoms sub-directories and drag them onto the “Solids” game object in the Unity “Hierarchy” panel.
  5. Optional: As the (large) terrain object for the region is imported it is usually split automatically by Unity into three sub-meshes of less than 64k polygons. These are all under one object named the same as your OpenSim region and will have sub-mesh names starting “GEOMETRY_”. You may wish to move this terrain objects and its three parts to the “Terrain” object in the hierarchy for tidiness and ease of management.
  6. Select all the objects in the Phantom directory and drag them onto the “Phantoms” game object in the Unity “Hierarchy” panel.
  7. Optional: Add a water layer at 0,0,0. [Instructions in YouTube Video][2:23] to [6:10].
  8. Optional: Add a ThirdPartyController/Avatar to be able to run the scene and view the contents. [Instructions in YouTube Video] after [6:10].

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.

Make a copy of the base project you created, or create a new unity project andimport 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.

Advanced Uses – Settings

OAR Converter has Tools and Settings to allow for a range of more flexible uses. As well as Collada .DAE files it can create .STL files suitable to drive 3D printers.

Exported objects can be shifted in the X, Y and Z (up/down) directions, perhaps for multiple side by side regions on a 256mx256m grid. [Note: this is also easily done afterwards in the Unity editor also.]

Once objects are converted they can also be examined in a 3D viewer built into the tool.

Access via a Virtual World – Sinespace

The region can be made available for use by multiple simultaneous users using Massive Multiplayer Online (MMO) servers or platforms. One example is Sinespace.

For more details see the Sinespace Wiki or tutorial videos:

The OAR Converter creates a lot of materials with repetitive (identical) textures. These are used to maintain other properties of materials such as shininess used by the Shader used to import OAR Converted content (via Editor/SelectOARShader.cs). This leads to rather large regions in Sinespace and hence larger than necessary download sizes for users using the content. The Sinespace developers have provided a useful and effective tool to reduce the repetitive textures used without effecting the visual appearance of the imported content. Always use this tool before uploading the region containing OAR Converter content before uploading a region to Sinespace. Use it via the Unity3D “Sine” -> “Tools” -> “OAR Material Cleanup” menu. The Sine menu is added to Unity when the Sinespace unitypackage is imported as described in “Sinespace – Getting Started“.

In recent versions of Unity and Sinespace there can be some bright emissive objects created by the OAR Conversion process which are due to the use of “Legacy” shaders in Unity. These can be changed to Standard shaders (Standard/Diffuse or Standard/Diffuse-Emissive) in a bulk fashion, but some manual tidyup afterwards might be necessary especially to correct for the addition of shininess and metallic effects, and for emissive and semi-transparent objects.

Example OAR Conversions Used During Developing and Testing

DirectX and Missing .dll

Some of the image conversion or other packages used by OAR Converter will use Windows OS utilities or .dll libraries which are normally installed. If you get error messages about missing .dll files look online for advice. Try always to use official download links at Microsoft and the full install of the missing elements for such packages rather than using third party download sites just to get the specific .dll file. Such sites can be a source of viruses and Trojans, or point at commercial utilities marketed as driver repair systems. A user also reported that this may occur when trying to run OAR Converter from Google Drive, rather than directly from local disk.

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 the “Space City region in Sinespace grid. This uses one of the freely available 3D models from NASA. The area is being used for a farewell party for Cassini and to watch the live feed from JPL as Cassini soars into the atmosphere of Saturn. You can join in on a Windows or Apple Macintosh desktop viewer (preferred) or in WebGL in a suitable browser like Firefox or Chrome.

Sinespace – RGU Oil Rig at Night

The RGU Oil Rig is now in a single region which is on a 4-hour day/night cycle (similar to that used on Second Life, Visit via http://sine.space/locations/oil-rig

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, particle effects, sounds sources, lighting and the replacement of the active information “i” signs for training purposes.

AI Rules – Oren Etzioni in NYTimes Opinion Pages

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 Roller Coaster

Universal Orlando Dueling Dragons PosterDueling 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 Hungarian Horntail (Ice). It was opened on 28th May 1999 and was converted to become Dragon Challenge in 2010 to fit into the Harry Potter theme of the area. After some accidents related to injury caused 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 and some other roller coaster simulators.

NoLimit2 Dueling Dragons by Z617Jason

This is my favourite fan-produced version of Dueling Dragons from NoLimits Exchange.
http://www.nolimits-exchange.com/coaster/dueling-dragons/10261





NoLimits2 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.

Sinespace – Load Test 1-Sep-2017


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.
  4. When the avatar is mid way through a quest, it seems that the quest information sticks on screen and cannot be dismissed, terminated or minimised. This takes up necessary screen space during unrelated events and ruins screenshots including the UI.
