The social consequences of the architectural decisions that will take us into a future of openness in immersive software are potentially vast. Open immersive software is poised to begin to play a disruptive role in the next generation of the internet, and decisions about its design may turn out to be very important ones for all of us.

EbenMoglen Euler the Second Life avatar of Eben Moglen of the Software Freedom Law Center), and Zero Linden (Mark Lentczner, Linden Lab), Neas Bade (Sean Dague, IBM, Linux Technology Center), and Zha Ewry (David Levine, IBM Research) met in Second Life last Sunday to discuss crucial issues of open architecture for immersive software in a discussion on Intellectual Property and Privacy/Identity in Open Virtual Worlds facilitated by John Jainschigg and I that kicked off Life 2.0 Summit Spring ‘08 (more details on the panelists here).

It was, I think, a landmark conversation. And, with the permission of United Business Media, here is an exclusive first chance to hear it, if you missed the live event Sunday.

Open Virtual World platforms are just beginning to get on the radar. But open software is clearly the path to the future and as Philip Rosedale (founder of Linden Lab) has said several times re the complete opening of Second Life software (the client is already open), “Only open will win!”

In two weeks, I will be part of a round table at Virtual Worlds 2008 in the new enterprise track. This round table aims to give people an opportunity to see a variety of implementations of open source virtual world platforms and to learn a bit more about the individual platforms presented, and what they are trying to achieve. Adam Frisby of OpenSim, Nicole Yankelovich of Sun’s Project Wonderland, Jani Pirkola of RealXtend, Remy Malan of Qwaq will be the co-facilitators

Avatar Rights!

At the heart of the discussion with Eben Moglen about freedom and openness in immersive software were some propositions about avatar rights. And, as Zero Linden explained, the new open architecture of the next generation of the Linden Lab grid crucially separates avatar identity from what constitutes their environment. Separating the production of identity from the material substrate is, Eben Moglen explained, at the core of avatar rights. (For a technical view of the next generation of architecture for Second Life see the first draft of Second Life Grid Open Grid Protocol a.k.a. SLGOGP, and for more on these protocols see Tao Takashi’s (Christian Scholz in RL) blog. where the stream for yesterday’s Architectural Working Group 2 meeting held in Second Life is posted.)

Eben Moglen put the fundemental issue of rights in immersive software very eloquently at the start of the discussion. I have transcribed the beginning of this discussion but to see how the thoughts developed through an in depth probing of the issues, you will need to listen to the audio here.

Eben:

I think we have an interesting and powerful problem to put our minds to with respect to want it means to think about freedom and openness in immersive software. The free software movement which I spent a lot of time trying to understand and in trying to assist took for granted that the person who needed to have rights in software was the person who got a copy of a binary, and that his rights in the binary should include the right to understand, and to study, which implied access to the source code, to modify, improve and share.

Now the reason for getting into OpenSim and open virtual worlds is to achieve some of the same kinds of social consequences that the free software movement was trying to achieve including innovation that can be shared by everybody that innovates and the value of technology in commons. But, because this software is immersive software we have another set of values to take into account which are closer to rights for users who don’t have a copy of the binary, or at any rate, whether they have a copy of the program on the client side and may posses some of the code derived from the server is sort of less important than the fact they are inside the software and if they are not free inside the software, they are substantially unfree.

That led me to ask some questions about what it means for an avatar to exist as a beneficiary of the freedom that the user is supposed to get in relation to software. It seemed to me that from there one could begin to try to deduce some rules about how the open virtual worlds have to operate. The most important one seemed to me to be that there is a right to continuity. To have the avatars existence and accumulated experience trapped inside one Terms of Services contract raises the the possibility of what lawyers call unconscionability. That after a while you have so much accumulated value in the avatar that the Terms of Service can be changed on you in a way that you can’t very well resist.

That implied, it seems to me, that if the spaces in the virtual worlds are to be regarded as open they have to be contractually open. It has to be possible to move between them without being artificially constrained by Terms of Service Agreement. That also seemed to me to imply something about the question of what it was one carried from place to place. And it seemed apparent to me that in the process of traveling from place to place an avatar has to carry some rule set as was true in many parts of the world before the modern era of the Nation State. The law that you obeyed traveled along with you. And it seemed to me that we were talking about a situation very much like that.

If you move an avatar in open virtual space from one part of the grid to another or from one grid to another governed by different servers one is not in a position to be asked to surrender ones’ sense of fairness or ones’ understanding about what can be done as a consequence of standing in a particular place. And so I reasoned my way to the conclusion that we had to provide an infrastructure for both declaring persistent preferences and expectations with respect to treatment.

Those were the lines of thought which led me to the propositions that Tara5 explained. And they seemed to me merely propositions in search of simplification. I feel as though I’m looking for some axioms, like Richard Stallman’s four freedoms in the free software movement’s genesis to explain what it is that we need to do as we open the space up.

Zha Ewry:

Reacting on that just a little bit, one of the things that came to mind when I heard Eben talk back in December is something Zero actually said when we did the kick-off, back in I guess September now, for the Architecture Working Group and some of the inter-op work which was, he used a phrase I liked a lot which is “an avatar bill of rights.” It’s what are the expectations an avatar should have in a virtual world. I thought that was a very compelling way of expressing it.

Zero Linden:

I believe at the initial Architecture Working Group which is Linden Lab’s sort of open forum for developing an open protocol set we used the term - looking for “an avatar’s bill of rights.”

I think I would respond to those two thoughts that are quite good. In one case I can give you a different approach for why we came there, and the other I can give you a simplification, which I think you’re looking for. In the first case, when I looked at viewing what would have to exist in an open virtual space, and the value of immersion. Strictly looking at it from the point of view of what made this space work. Granted here I’m a technologist not a lawyer so I’ve perhaps a different view, but surprisingly the same conclusion, is in fact the ability for you to identify and for you to to associate so closely with your avatar that led me to posit as a fundamental aspect of how we build this future open protocol that you must think of it as avatar portability.

It must be a fundamental right that users are in control of their identity not the services which help provide the existence and the immersion. That’s pretty radical thought actually, at least in terms of technology, because it is so much easier to architect, and so much more quote unquote natural to build systems which work another way. Witness every single web-site where you create your own account on every single web-site, it’s much easier for each web-site to do that than it is for web-sites to understand that they somehow agree to opt into a protocol in which you can control your identity.

In virtual world services, we have to have a world in which your avatar and your identity are in control of the user not matter what the service provide is. So what is going on in the AWG and the structure of the future protocol is the surprising separation at the server side, at the internet side, of those services that provide aspects of you identity. And by separating those out, and by building the entire protocol based on a mutual understanding between those two sets of servers, we enable users to choose servers to represent their identity that meet with their needs, trusts and ideals and to still interact with other servers that provide land with other things.

Right now when we are standing on this piece of land, the server we are standing on is both providing our identities as well as providing the land. And if you come to visit this piece land you basically have to trust what this server decides your avatar can do. In the future open that we are deciding we separate those notions. There is a server which represents your identity that you have chosen, and there is a server that represents the land that the landowner has chosen. And, we embed in those systems the negotiation between them.

Eben:

That is beautifully elegant, I have to say. That does indeed make an enormous difference………(to continue please go to the audio here).

Also see Sean Dague’s (IBM and OpenSim) interesting post on his blog that highlights one of the key freedoms Eben discussed - the freedom to leave.

“freedom to leave”, an open-standards based assurance that users can move their data easily between interoperable platforms and services.

Sean notes:

Today, if you decide to leave any virtual world platform (even OpenSim), you pretty much have to leave you data behind. I think that one of the features people will be looking for in the virtual worlds of tomorrow is the same freedom to leave that they get from any standard web or mail infrastructure provider today. Part of what has made Google successful in the application hosting space is by ensuring it’s easy to leave the platform.

One of the biggest reasons I left LiveJournal was that it was hard to leave, and the longer I built up content in that environment, the harder it was going to be for me to get it out.

Mitch Kapor - Second Life 2.0

In his keynote at Life 2.0 Summit Spring ‘08, Mitch Kapor predicted that virtual worlds will become a very important part of corporate strategies for adapting to a world defined by global warming. Kapor the recent board chair of Linden Lab (now a board member), chair and founder of the Open Source Applications Foundation; co-founder of the Electronic Frontier and Mozilla Foundations; and the creator of Lotus 1-2-3, the spreadsheet that revolutionized enterprise computing in the 80s spoke about his current work to enhance the user interface for virtual worlds, which he likened to being in the DOS stage now. His vision to make virtual worlds useful and accessible to all is backed by work on in his own lab. He noted that videos of some of these experiments will be available on You Tube in a couple of weeks. See Hiro’s epic post for more. Kapor also made some comments re the open sourcing of virtual worlds.

I am personally very encouraged at the progress being made with OpenSim and open source components of a virtual world eco-system- some people inside the company at Linden may feel threatened by this. But my personal view all along is the most important thing that can happen is to have the largest most vibrant innovative ecosystem for virtual worlds as possible. And that means something that is open and interoperable. One wants to have the biggest pie not a little slice of a small pie. And similarly I know that there are a lot of people interested in avatar portability or open avatar in the company.

This last remark I think is clearly supported by the number of Lindens that came to the annual open Architectural Working Group meeting. I attended and there were indeed a bunch of Lindens present. The picture below is from Tao Takashi’s (Christian Scholz in RL) blog.

Eben Moglen - Open Source, IPPI panel in Second Life

Life 2.0 Summit Spring ‘08 will kick off with the Open Source, IPPI (IP and Privacy/Identity) in Virtual Worlds On Sunday, March 16, at 1 PM PST, with special guest Eben Moglen (his avatar pictured above).

The event will be held in the CMP Amphitheater at CMP 1, 2, 3, 4 ( SLURL ). To attend the Second Life events or watch video you must register for Life 2.0 here.

Eben Moglen, is Director, Chair and Chief Counsel of the Software Freedom Law Center. Moglen, professor of law and legal history at Columbia, is a pioneer of the opensource movement, former general counsel for the Free Software Foundation, and one of the architects of version 3 of the GNU GPL.

Zero Linden

Eben Moglen’s co-panelists on Sunday will include Zero Linden, a.k.a Mark Lentczner, Linden Lab. Zero is one of main the architects of Second Life’s evolving infrastructure. Zero recently published the first draft of Second Life Grid Open Grid Protocol a.k.a. SLGOGP a important step forward on the path to opening up the Second Life grid (see Tateru Nino’s post on Massively, Tao Takashi’s post at mrtopf.de, and mindblizzard).

The brilliant and very elegant Zha Ewry (a.k.a David Levine, IBM Research) will be joining the panel from JFK airport while he waits for his flight to San Francisco. David Levine and Eben Moglen had an interesting conversation back in December that you can find on Ugotrade here. They explore some of the problems of defining digital public space and issues of privacy on the internet, offering many suggestions on how to implement online privacy enhancing technologies and insights as to how we could design the next generation of these technologies in responsible ways.

Also Zha was a interviewed recently on Metanomics with Beyers Sellers (a.k.a Robert Bloomfield). This interview is highly recommended as some of the key issues facing Second Life’s Architecture Working Group (AWG) and a future Open Grid “that will ultimately allow the cohesive operation of both Linden-operated and non-Linden-operated Second-Life style simulators and grids.” (see Massively for more) are unpacked.

Tara5 Oh (below - that’s me!) will moderate with CMP’s John Jainschigg (John Zhaoying).

See you there! (SLURL)

We have built the technology for monitoring almost everything, almost everywhere and we are making 99% of it open-source. Thanx to Bruce Sterling who inspired us, we called our technology “OpenSpime.” This is a concrete opportunity to monitor the earth, and everyone on this planet will be able to contribute to this.

OpenSpime have prepared a concept video of CO2 monitoring (still from the video above) and Google maps mashup via their OpenSpime infrastructure. For more see, co-founder, David Orban’s post OpenSpime: What do you know about your planet?

Instrumentation versus Surveillance

Surveillance is all about when people in authority know a lot about you. Instrumentation is when you know a lot about the world. And it allows you have more agency. When people know a lot about you it takes away your agency.
Cory Doctorow, Craphound.com, boingboing.net

OpenSpime and SL Data Viz project (a project in Second Life “where people can contribute, review and copy open-source data viz tools” which OpenSpime will participate in) are taking up the challenge that Bruce Sterling made at end of his visionary book, Shaping Things. Sterling gave an imperative to humankind to start to make “decent technology” - social software entities that can answer questions. Questions about our world. Questions about objects. Not the profit-centric questions - serious questions. (Shaping Things).

The protagonists of this new era of social software - the narrators of the instrumented world to come - are Spimes.

Sterling invented the term by compressing ’space’ and ‘time’. Spimes are aware of their environment, they know where they are, and when they are, and keep track of some parameter around them. Sensing, memory, and ubiquitous communication enable spimes to accurately map the physical world around them. The progressive saturation of the world with spimes is creating what is called the Internet of Things.

The closing words of Sterling’s great visionary book on “spimes” and “the internet of things” are:

Its not enough to think about that, or even write about. If it is to be any use to humankind, it will have to get done.

OpenSpime is doing it! SL Data Viz project is doing it!

If you are not yet in tune with “the internet of things” here is a music video Royksopp’s “Remind Me” that Sterling suggests is some kind of “spime” theme song. This is the third time I have posted this link but Spimes deserve all the air play they can get!

Our technology enables individuals and corporations to better understand their environment, through the use of a series of GPS-enabled sensors. We provide a set of open APIs and communication protocols to manage the data collected.

See an interview with the founders of OpenSpime here.

With free hardware, free software, open APIs and communication protocols, OpenSpime’s business model is about the provisioning of the SpimeID identification numbers for the trusted communication of validated data streams between spimes and the OpenSpime servers.

Here are David’s responses to questions about the revenue model:

The revenue model is based on the sale (in large quantities to the hardware makers) of the certified SpimeIDs. Anybody can build spimes that conform to our open specifications, but if you want us to validate the data that your spime collects, and aggregate it together with other trusted sources, than you have to pay €1 per device to get the ID. Ah, and we already have LOIs for several hundred thousand IDs to be built in devices. [smile]

The estimates are that there will be ten or more spimes per person in the developed countries within ten years. That is approximately 25 billion spimes, and counting, since by 2020 the number of people who live in countries we define developed will also increase. That’s a
market for you! And we want to define the way the data generated is managed.

What comes after humans twittering to each other? Spimetalk. And spimetalk is going to be several orders of magnitude more intense than any human2human or human2machine communication before that.

From Spimes to Mirror Worlds

Agents, avatars and spimes will eventually hang out together in Virtual Worlds, interacting in real time in networked virtual environments built of live data and 3D info machines.

Melanie Swan points out:

Virtual Worlds have been used for architectural builds and interaction and the next obvious step is making them alive with data, streaming in data and representing it visually. Data visualization in Second Life is starting to take off with an open-source movement to make open-source building-block tools available to the community and developers and end users creating specific-purpose enterprise and science applications. There is a community wiki and a “Data Visualization” group in Second Life.

The picture above is of a Bashiba Panorama - “a commercially available ambient data panorama that dynamically reflects the overall “mood” of a rich information environment. The so-called “data atmosphere” reacts in real-time multivariable changes (e.g. stock market data), that are then mapped to visual counterparts (e.g. ocean waves, sun strength, wind speed, rain). the resulting information display can be interpreted ‘without cognitive effort’.”

“once the stock market opens, our 3D simulation comes to life, & people start ‘breathing’ business information.”

The streaming Bashiba Panorama in Second Life is an experiment in collaboration with Melanie Swan (MS Futures Group) and powered by the Ohio University VITAL Laboratory streaming server (many thanks to Dr. Chang Liu + Stephen Carroll). Look for Bashiba to come to Second Life in full immersive 3D!

3D Command Centers the killer app of the 3D Internet

A Mobile Tactical Data Comm Unit built by Illuminous Beltran in OpenSim

Data visualization will develop increasingly into and become inextricable from operation/command centers - the 3D information machines that will reinvent the relationship between humans and the up to now invisible but most crucial layer of modern society - software. For more on Illuminous Beltran’s, (a.k.a Michael Osias, IBM) virtual operation centers/command centers in Second Life/OpenSim see here.

These 3D command centers are being used for energy management, virtual network operations centers, and for building automation (see the work of Eolus). But, as long as our society is wedded to war, the “killer app” of the 3D internet will also be a killer app in more ways than one. The instrumentation of society has grown up hand in hand with surveillance and military technology. But it is up to us, as a society, to grow the peaceful and people centered aspects of this technology.

The nascent spiming technology of RFID had its roots in military innovation.

In 1946 Léon Theremin invented an espionage tool for the Soviet Union which retransmitted incident radio waves with audio information. Sound waves vibrated a diaphragm which slightly altered the shape of the resonator, which modulated the reflected radio frequency. Even though this device was a passive covert listening device, not an identification tag, it has been attributed as a predecessor to RFID technology. The technology used in RFID has been around since the early 1920s according to one source (although the same source states that RFID systems have been around just since the late 1960s).^[2][3][4][5]

Similar technology, such as the IFF transponder invented by the United Kingdom in 1939, was routinely used by the allies in World War II to identify aircraft as friend or foe. Transponders are still used by military and commercial aircraft to this day. (for more see Wikipedia on RFID)

But, Gelertner’s vision in, Mirror Worlds 1991, is the transformation of computers into seeing machines that will empower people to understand and work with the machinery of their society. And with projects like OpenSpime everyone can contribute to the task of asking important questions about our world. And as these questions are increasingly incorporated in virtual operation centers, we will be able to interact with the previously invisible machinery of our modern world - tinker with it, hang out in it with other avatars, and agents, and command it in new ways.

Life2.0 Summit Spring ‘08

Life 2.0 is the leading event on virtual world application and business development. Produced three times yearly by CMP in Second Life, the six-day virtual event draws a fully-registered, global audience of over 1000 software architects, creatives, CMOs and key executives seeking to harness the power of virtual reality for marketing, application creation, commerce, education, and to connect with the Net’s fastest-growing, smartest, most-engaged communities.

Also check out CMP’s John Jainschigg’s (John Zhaoying in Second life) post, “Life 2.0 - As green as Five Brazilian Households,” which demonstrates “that importing certain kinds of real-world activities into virtual reality saves a bagload of carbon. Or put another way, that it enables us to enjoy the benefits of global human community at small cost to the planet.”

Eben Moglen to join IPPI panel at Life 2.0 in SecondLife

Tony Manninen, the CEO of LudoCraft games studio (the client side development division of realXtend) who has being doing all this amazing recent development on OpenSim, has a vision for Avatar 2.0 that he is bringing to OpenSim. The possibilities for the future integration of realXtend features (that include meshes and the ability to import proper 3D models) with Second Life is currently under discussion - more on this soon.

We have tried to keep the rexviewer as compatible as possible. We totally appreciate what Linden Lab has done and we are trying to do our best to co-exist with their beautiful social innovation.

When I interviewed Tony (see interview later in this post), I was very excited not only by the scope of his vision and his devotion to enhancing the user experience and possibilities of virtual worlds, but also by his absolute determination to manifest this vision in code with the the utmost speed

The next release of realXtend server and client will be published on 29th of February, 2008 at 4pm (Helsinki time). The features that will be in this release and a roadmap for the future are here.

Virtual Worlds that make our “real” and “virtual” lives better

What do I mean by an exciting vision for virtual worlds? There are many visions for virtual worlds floating around and some of them are not so appealing to me, like the notion of a virtual world as a walled garden/company town put forward by the CEO of There.com, Michael Wilson.

When Michael Wilson was interviewed in Second Life by Beyers Sellers (Robert Bloomfield, Cornell University) for Metanomics this week, he gave the impression that creating a controlled environment for marketing is the number one priority of There.com.

In my view, which seemed to be shared by many of the Second Life audience participating in the group chat, this notion of designing virtual worlds as “big brother houses” is the epitomy of “the metaverse gone wrong.” You can see the full interview here on SLCN. Also see here for Christian Scholz’s (Tao Takashi in Second Life) excellent summary and analysis of a virtual world according to There.

I hope there are some more positive aspects to There.com than this interview conveyed.

Despite ups and downs and growing pains, Philip Rosedale’s vision for Second Life has always, in my view, had at its heart the motivation to make people’s “real” and “virtual” lives better. See The Making of Second Life by Wagner James Au for a fascinating look at the early days.

While Linden Lab is still working hard to break free of the “walled garden” model, with OpenSim and realXtend, the expansive vision that they have pioneered has been open sourced even before they have finished their own open sourcing project. And now, an open source development community of genius and depth (including Linden Lab) is rising to the challenge of taking this vision of making our “real” and “virtual” lives better to the next step.

There are several Open Source virtual world platforms available now, including Ogoglio, Croquet and Sun’s Wonderland. In the news today is the Open Virtual Worlds Project from The New Media Consortium (NMC) and Sun Microsystems which as VWN points out is similar to efforts announced by the Immersive Education Initiative to create an Education Grid across Second Life, Wonderland, and Croquet.

But OpenSim stands out from the pack because it inherits from Second Life an awesome set of tools to facilitate user generated content. This emphasis on user generated content is, of course, key to how Second Life has become the largest and most highly developed 3D immersive world to date. The fact that OpenSim is a platform built for people to build in was of one of the reasons that realXtend chose to work with OpenSim after they investigated all the available open source options. Also important, Tony noted, was the depth of the development community in OpenSim and Second Life.

The Future of Ubiquitous Game Design

There are many inspiring alternative visions for virtual worlds emanating from Game Developers Conference 2008 which have been percolating through the blogosphere. Particularly interesting, to me, are the new possibilities for avatar expressiveness and some interesting ideas on the future of ubiquitous game design.

I was thrilled to discover that Tony Manninen has been doing research on avatar expressiveness since 2000 (see his papers here). Rich Interaction in networked virtual environments, avatar expressiveness, and the future of ubiquitous game design are his forte. How very cool!

Tony’s vision is to take social gaming to the next level and to produce games that are so heavily collaborative that they reach deep into our experience of the pleasures doing things together, our enthusiasm for team sports, and childhood memories of the enjoyment of playing together. He has been exploring these ideas of team play and community in earlier LudoCraft games like AirBuccaneers.

Ray Kerzweil’s keynote GDC 2008 laid it on the line: “Games are the harbinger of everything.”

But some of my favorite GDC 2008 quotes are from Jane McGonigal (see her blog post “Reality is Broken” - My GDC Rant) and in Liz Lawley’s copious notes on “Pouring Fuel on the Fire: Game Designers’ Rant.”

Jane McGonigal: I’m not mad at game designers. Compared to the rest of the world, we have it all figured out. Our medium kicks all other media’s ass. We make more people happy than any other platform or content in the world. (If you don’t believe that, you’re not paying attention to what’s happening.) We’ve won. Games have won. As an industry we’ve spent the last 30 years learning how to optimize experience. Brains, bodies (recently), and hearts are all engaged. That’s the good news.

The bad news is we rule the virtual world only. Reality is broken, and we’re not fixing it, we’re offering alternatives to it. We offer better experiences, better socialization, in virtual experiences. That needs to start changing. If reality is broken, why aren’t game designers trying to fix it? It’s our responsibility to design systems that make us happy and successful and powerful in real life? We have the power and the responsibility.

Jane shows an image of her favorite “I’m not good at life.” graffiti (from Liz Lawley’s notes).

Tony Manninen is an innovator committed to bringing the power of games into arenas we are yet to dream of.

Jane McGonigal has some nice examples to stretch your mind in this direction. For example, the Sniflabs collar remembers other dogs you’ve encountered. “We can play games with our dogs. What if I could play an MMO with my dog?”

Why will it make our “real” and “virtual” lives better to take play into every nook and cranny of our experience? Because, as Kurzweil points out, “Play is how we principally learn and principally create.” Jane McGonigal goes further:

I have spent the last year doing research on happiness. Instead of trying to figure out what’s broken, these people are trying to figure out what makes us happy. Every positive psychologist has found the same thing. Happiness is 1) having satisfying work to do, 2) the experience of being good at something, 3) time spent with people we like, and 4) a chance to be part of something bigger than ourselves.

“If you are a game designer you are in the happiness business.”

At the Metaverse Roadmap meetup, Mitch Kapor pointed out “3D cameras would make virtual worlds easier to use.” And Bob Moore (on left above, me on right) asks in this excellent post, Is “free gesticulation” for avatars here yet?

When I asked Tony this question he replied:

“Our avatar will have enough “bones” for full facial expressions, etc. When the actual base architecture of the avatar is fully functional, there’s a possibility to use webcam, voice, or other input devices to control your avatars facial expressions. It can be true 1:1 mapping, but of course it can be something else as well. You can be yourself, or, you can change your “output” to something else.”

Tony, through realXtend, is reinventing the technologies of expression and experience.

Interview with Tony Manninen, LudoCraft

Me: Second Life as a platform has been pretty much ignored for game development up to this point. Do you imagine transforming OpenSim and Second Life into platforms suitable for MMOG?

Tony: I am running the company and also making sure the realXtend development reaches the required quality and performance standards you would expect from MMOGs.

We’d definitely love to make games for Second Life, but at the moment the end-user experience is not exactly what you would expect from a game system. Therefore, we’ll pay heavy attention to things like responsivity, graphics quality, frame rate, etc. If we manage to keep up the momentum of realXtend development, then I’m sure there will be some interesting games spawning up in the near future…

Developing a sophisticated game engine is not an easy - or cheap - task, so there’s a loads of challenges ahead. But I truly believe that is the only way forward. With game-like interfaces and features you’ll be able to get much more heightened experiences.

Me: Have you worked out anything with LL yet re keeping the realXtend viewer compatible with SL?

Tony: We have tried to keep the rexviewer as compatible as possible. We totally appreciate what Linden Lab has done and we are trying to do our best to co-exist with their beautiful social innovation.

Me: But will you be able to work out a licensing deal under the GPL so that they can integrate your code into their browser?

Tony: The whole licensing scheme is still undergoing some serious thinking processes. We will try to find the best possible option in order to satisfy the needs of hungry virtual world adopters. GPL has its challenges. But, on the other hand, everything invented by a man can be re-invented by another. I am sure there will be a fruitful solution to the licensing issue. At the moment we are concentrating on releasing all the code to the general public, so that all the enthusiastic developers out there can join the forces and increase the momentum.

I’m pretty sure the pieces will eventually find their right places. I am really happy about the response we’ve got from Linden Labs - it’s great to think we might be able to give something back for them.

Me: Is it safe to say the licensing issues are on the table and being worked out?

Tony: There’s definitely some serious working-out being done, so I suppose it is safe to say that.

Me: I know Will Wright creator of Sims online and Spore has spoken a lot on the spiraling costs of content production and that diminishing returns for content development at these high costs. He has gone to procedural programming with Spore to take gaming on another path. But, it seems to me that you are taking another approach by trying to bring SL up to gaming standards - is this correct, or are you doing something different?

Tony: I guess that’s quite correct assumption - at least in relation to LudoCraft. This is not necessarily a conscious decision. It’s more like the costs of licensing a decent game engine are generally so high that they more often than not fall out of reach of start-up companies and small developers - let alone universities, communities, etc.

We have tried to find a suitable platform for our collaborative games, but since there were no perfect solutions, we decided to try and make one. Not alone, but by joining forces with our partner company Admino and several other keen developers.

The OpenSim merger will increase the development base even further, so there’s a great chance we’ll actually pull this off.

Like I said, there’s loads of challenges, huge amount of work and some design issues involved. But the Open Source communities have proven themselves earlier, so why not now.

Me: What do you think are the chief design issues to be addressed?

The realXtend project includes LudoCraft and Admino, plus we have several sub-contracting developers doing work with us.

The main issue is the divide between social 3D worlds (like SL for example) and MMOG. The gamers tend to avoid these social virtual worlds for obvious reasons [the quality of the experience from a gaming POV]. However, if we manage to develop a platform that can serve both purposes, then I’m sure things will change.

The main design issues, therefore, are the performance, audiovisual quality, rendering, frame rate stability, responsivity, interaction, etc.

Numerous issues that are not necessarily critical in purely social virtual world, but are absolutely essential in any multiplayer game environment.

Plus, if well taken care of, these issues will boost the whole end user experience in the non-gaming situations as well.

Me: You have gone a long way with the rendering and meshes what will be the next most important features and when do they arrive?

Tony: Inverse Kinematics and procedural animation are essential features if we want to have truly expressive and adaptive animations. We see avatars as main tools for self-expression. We’ve researched the issues since 2000 and we believe we are on the right track. With flexible and powerful expression potential and accurate controllability, the users will be able to communicate with their avatars so much more than is possible nowadays. The concept of Rich Interaction is something we will utilize here and it will be interesting to see the results when the system is actually usable by the general public.

Vehicles and projectiles are really important so they sit heavily on our roadmap.

Me: Are you going to do 3D face mapping etc - I know that this is getting close to doable now?

Tony: Oh, the required list of features is endless. There are several key features in terms of game development, but also some interesting stuff for more serious applications.

Our avatar will have enough “bones” for full facial expressions, etc. When the actual base architecture of the avatar is fully functional, there’s a possibility to use webcam, voice, or other input devices to control your avatars facial expressions. It can be true 1:1 mapping, but of course it can be something else as well. You can be yourself, or, you can change your “output” to something else.

Me: OpenSim is very attractive for a number of vertical applications - building automation is one you mention. How focused are you on getting the OpenSIm platform ready for the huge mirror world, 3d info machine/command center market?

Tony: In terms of the mirror world, we already have some interesting pilot projects that target those features. It may be less juicy than making cool games, but it provides some highly interesting scenarios.

Me: What are your pilot projects?

Tony: I don’t think I should go into details at the moment. We will include a list of initial projects and collaborations for our next announcement, which is due 3rd of March (latest). We want the third parties to have their saying first before making these public.

Me: The realXtend avatar server is a new way of connecting sims - could you tell be more about your vision there?

Tony: The main vision is: there should be only one. Only one avatar, one user account, one login, etc.

It is ridiculous that I need to have an avatar in SL, character in WOW, nickname in IRC, and whatnot. I mean, it’s ok if I want all these different identities, but what if I would be, eh, me in all these worlds, perhaps doing business, shopping, hobbying, and so on. There should be an option for me to jump from world to world without the hassle of logging in and logging out

Me: And how will the work you have done on the avatar server alleviate this problem unless SL, WoW and other cooperate on interoperability?

Tony: Think of it more like the 3d web. realXtend/OpenSim is like the Apache of virtual worlds, rexViewer is the Mozilla or Firefox of whatever. When “surfing” the web, you are not constantly required to prove and change your identity when loading different pages.

Me: But because there is no equivalent of http for virtual worlds yet, how will this work re the other worlds?

Tony: Ah, that’s the critical question: it won’t. There is some interoperability work going on in terms of creating the standards. The problem is, this work tends to be slow. We are not willing to wait that long. We want to see some action. That’s why we thought that we’ll start the wheel rolling and then see what happens.

Me: So at least now OpenSim worlds and hopefully Second Life will be able to connect this way?

Tony: The openess is the key to the lack of unified protocols. When the interfaces and APIs are open and transparent, people are free to develop applications, converters and bridges between different systems.

Right, at least OpenSim is now reachable, plus we want to get the teleport between SL and OpenSim/realXtend up and running, at least in the quick-and-dirty way so that people will have a chance to experience the feeling of world-to-world hopping.

Me: So in terms of this experience of avatars hopping between OpenSim worlds how do you think this will change the need /or not for large grids like SL or any of the new ones like OpenLife that are springing up?

Tony: I think there’s still need for various technical solutions like there is need for lighter and heavier websites. There are different applications, different scenarios and different user requirements. It is still really enjoyable feeling to be able to actually walk - ok, virtually at least, from one server to another. With hopping there may be some loading involved (like when surfing the web). So I guess the big grids won’t go anywhere. We’ll just have more modalities in terms of servers/worlds.

Me:So what are your expectations for concurrencies on OpenSim in the near future?

Tony: Hmmm… I’m not sure yet. OpenSim is an excellent initiative and there’s already a substantial user base. There are a lot of work to be done in terms of integrating realXtend codebase to the OpenSim, but since the visions and missions of the people involved are aligned, the hard work is a minor detail in the process.

Michael Osias, IBM (a.k.a Illuminous Beltran in Second Life) has been working hard to make virtual worlds useful places. And, today, the 3D Data Centers that Michael has pioneered in OpenSim (also demoed here in Second Life) appeared in Earth Times, CNNMoney.com, Trading Markets, Street Insider, Sys-Con, Biz.Yahoo, Marketwire, Foxbusiness.

The picture above of Illuminous Beltran at his Virtual Network Operation Center in SL was taken by Noelani Lightfoot, the proprietor of Quixotic Photography in Second Life (see more of her great work here).

Also noted in this recent flurry of press is the work of Oliver Goh, Implenia, (a.k.a Eolus McMillan in Second Life) and his collaboration with Michael. Oliver has pioneered virtual operation centers and dynamic 3D visualization tools for the Real Estate Industry - see Guardian.  And, see here and here for more about the Eolus One Think Tank in Second Life. Eolus One will be announcing their new project and collaboration tool - the 3D Balanced Scorecard and a 3D Virtual Risk Map (vital considering the recent ‘finacial crisis’ in the real estate industry) at MIPIM - the most important conference for the real estate industry.

The headline of many of today’s posts is “IBM 3-D Data Centers Show Virtual Worlds Fit For Business.” CNNMoney.com writes:

Real-Time Management of Global Data Centers Made Possible Through Secure 3-D Intranets Can Reduce Cost, Save Time and Help Reduce Carbon Footprint

3-D Data Centers, Virtual Operation Centers or more generally all manner of 3D information machines, have the potential to transform our wasteful industrial society, and eventually, together with 3D fabbers, will play a vital role in ending the unsustainable consumption of energy and natural resources. This kind of innovation will make virtual worlds fit for business. It will also make virtual worlds fit for society. The transformation of computers into “seeing machines” (Gelertner 1991) has the potential to empower people to understand and work with the machinery of their society.

I have blogged a lot about Michael’s and Oliver’s work in the past year, see: The Archeology and Future of Software Design: Interview with Grady Booch, Interoperability for Virtual Worlds in 2008, Eolus Goes OpenSim, Next Generation of Software Design: 3D Command/Service Centers in Second Life, Eolus Makes Leap to 3D Internet in Second Life. I see these pioneering integrations of “virtual” and “real” worlds as our first glimpse of better ways to manage our planet and our future.

Earth Times writes:

As companies of all sizes become more global in nature and tap into skills across the world, the mounting virtual workforce needs new tools to be effective. The 3-D Data Center allows experts to manage data center resources regardless of where they are or when these resources need attention, giving both employees and corporations enhanced productivity and freedom. A globally-integrated enterprise can deliver enormous economic benefits to both developed and developing nations, and new technology like this one can help companies seamlessly operate in such a distributed model. This type of collaboration provides much faster cycle times for analysis and decision making, by viewing operations in near real time, instead of exchanging messages and two-dimensional drawings via email.

This picture below, of the IBM 3D Data Center, was taken by the talented Noelani Lightfoot.

Also worthy of note is the work of the SL Data Viz project of Melanie Swan, Dave Taylor and others who are creating Data Viz Island in the SciLands where people can contribute, review and copy open-source data viz tools. Melanie notes: “I think data viz is the next obvious step for virtual worlds, streaming in data and making it ‘interact-able’.”

There are many RL/SL integration projects being developed, including, NOAA’s real-time weather simulation, 3d stock charts, LAX air traffic data. But as Melanie Swan points out: “An open source data visualization tool suite for virtual worlds is needed, something to be the Many Eyes or Swivel of Second Life and other platforms.”

The excitement in the open source virtual world developer community has been bubbling over since realXtend brought many OpenSimulator developers over to Finland to reveal the extraordinary amount of work they have done “extending” the function of the OpenSimulator project in just 4 months.

See here for an account of this amazing meeting in Oulu, Finland, by one of the participants from the OpenLife grid. Pictured above is a screenshot of the new mesh avatars being conformed inworld. Adam Frisby explained to me:

Meshes behave just like another prim type - you can drag, scale, and rotate meshes around using the same method that you use on primitives and object groups. You can link meshes with other primitives, save them to inventory and use them in pretty much the same way you use primitives.

Second Life is built with prims, so I asked my friend, Zha Ewry, for a 101 on meshes versus prims. “A prim, is a solid, defined by an equation - a cube, and such with permutations, like twist and taper, and cut. Whereas a mesh, is a series of triangles in 3d which conform to the shape of the object.”

Meshes are groovy because “they can do arbitrary surfaces. You can lay a mesh over any shape, add more triangles, increase resolution. A prim you can’t make any shape, only what the math bends it to, so you blend them into shapes by composition.”

SL originally went with prims and not meshes “because they are more compact, lower cost to render and easier to map to the physics model.” But, “many 3d programs build meshes by default and nothing builds prims,” so the introduction of meshes facilitates one of the key new realXtend features - support for proper 3D models.

I asked Zha if meshes would have a negative effect on concurrency. Zha said the answer to that question is not entirely clear yet, “but its not as bad as it seems because its prim+texture vs mesh=texture.”

Zha explained that a lot of people think of meshes as much more expensive when its not prim vs. mesh but rather, prim+texture vs mesh+texture so the difference is smaller, “and even more to the point, for many things, its Prim+prim+prim+prm+textures vs mesh+texture set. Often, even for small objects, you can do several prims worth of detail in a mesh.”

I have heard from OpenSim developers that the expectation for OpenSim is for concurrencies of 100 at least in the next six months.

Two realXtend companies, Admino & Ludocraft, have been dedicating 20 personnel (programmers, designers and content creators)‘ to extending’ the function of the OpenSimulator Project, both server side and client side respectively. The project is backed by the vision and generosity of Juha Hulkko, who has another fascinating project Radio Arkala (also in Second Life on Arkala Island).

Click on the screenshot above for the realXtend video demo. There is a full list of realXtend features on their site here. RealXtend give a summary of some of the most important functionality they have added.

The most important realXtend-specific development areas were the media tools such as VoIP and document sharing, OGRE renderer support and, of course, the separate realXtend avatar storage / authentication infrastructure that enables seamless transition from one world to another.

Having support for proper 3d models as well as simpler primitive type objects is an asset in many different ways. Most importantly, just about all the professionals and advanced amateurs who create content suitable for virtual worlds like to work with proper 3d modeling software. There’s already a lot of existing material that can now be directly transferred to the virtual reality if for example a movie maker wants to create a virtual world based on an animated film and the same goes for computer game developers. Thanks to proper 3d model support, practically all of their material should be easy to transfer from games to realXtend based virtual worlds and vice versa.

Another central feature is the global avatar architecture. A network of interconnected virtual worlds simply doesn’t exist until users can take their virtual representatives with them wherever they choose to go. Architecturally this means separating the avatar and their asset storage functionality from the virtual world server. Avatar service will provide the users with identity and authentication independent of the world they happen to be in at any given time. In practice the role of the avatar service will be somewhat similar to what email is today. Security is naturally a major issue whenever someone’s identity or asset ownership is concerned and it has been an important consideration in the design of the avatar architecture.

The picture below is of the web page as a texture feature.

Pictured below is the the location of this historic meeting which was also attended by Chris Collins of Linden Lab. I did hear some very interesting anecdotes about the visitors introduction to Finnish culture - flaming drinks, saunas, and hot metarati rolling in snow!!! But, the focus of this post is the road map for an open standards virtual world’s future, so I will leave it to others to tell those tales.

What follows is an extract from realXtend press release, and then I move on to an interview I did with Adam Frisby who was in New York last weekend. He shared some of his thoughts on the future of the Open Simulator project with me on another snowy weekend of skiing and snowboarding in upstate New York (lots of snow again but no flaming drinks, just Ribena, Mario Galaxy, and snowball fights with Ugotrade Jr).

Oulu, Finland - even a blizzard couldn’t delay the meeting

Team up to make open source Virtual World standard

Open source virtual world developers OpenSim are building a global standard to power the 3D internet, now joined by Finnish developer’s realXtend, OpenSim gains many new key features and technologies.

OpenSim is a free and open standard virtual world server founded at the beginning of 2007 by a small group of developers. The OpenSim platform can be used for creating and deploying immersive 3D Virtual Interactive Environments. The realXtend project’s mission is to assist in bringing forth the next generation of virtual reality development by focusing on interoperability technologies, usability and real-life application support. realXtend brings to OpenSim professional experience and development in the realm of 3D engine programming, voice over IP and network support, and is contributing many new features such as improved 3D graphics and voice chat.

“I welcome the realXtend project to join us. It is my pleasure to see that the OpenSim gets a huge professional code contribution. The future of the OpenSim project looks bright as the developer base continues to grow with giant leaps like this”, says OpenSim project manager Darren Guard (aka core developer Michael Wright).

realXtend is contributing all the server side code for their developments to OpenSim and continues to do so from now on. This collaboration of two projects with a similar vision enables realXtend and OpenSim to focus on common issues, and solve them more quickly - leveraging experience and knowledge from each party. realXtend project manager Jani Pirkola comments on the joining as “I see this as a great possibility to quickly make OpenSim the global de facto standard and to significantly speed up the global technology development in this area. Our common goal is to create the best open source virtual world server platform, and to continue the rapid evolution of OpenSim”.

Interview with Adam Frisby of OpenSim

Snowball fight in the Catskills while “snowed in with Open Sim”

Me: Could you tell me more about the “avatar server?”

Adam: The “avatar server” improvement allows you to sign in remotely from another region and bring your avatar & attachments across with you. It allows you to sign onto a OpenSim with an address like: adam frisby@mygrid.com — and then bring across your avatar & appearance. Inventory/etc is going to come in with this sign on method as well.

Me: You also mentioned to me how this would really change the concept of griding and introduce a different model to the Second Life grid.

Adam: Right, that’s tied in with that [the avatar server] a little - you don’t need a big central grid in the way they are operating. Their philosophy has been more akin to the world wide web — lots of interdependent sites that can link to each other. The avatar server is the first step towards that, since it allows you to login to multiple independent installations with one account.

Me: Do these changes, potentially, signify more of a fork from Second Life or not?

Adam: Definitely. This is the first time we’ve broken compatibility with SL feature-wise and implemented things that go far beyond SL.

Me: Will the Rex viewer work with SL?

Adam: You can still connect to SL with the Rex viewer, but your missing lots of nifty functionality, like the new rendering engine.

Me: What do you think are the implications of that and do you think the fork will continue to get wider or not?

Adam: Well, the subtle irony of it is that Linden Lab can’t take the changes back because of their client being GPL’d and they still rely on non-GPL’d components, i.e., FMOD and other bits and pieces. They can take BSD [all the realXtend server side work is BSD, but the client source code is GPL’d at the moment.
If we released the patches as BSD licensed, which RealXtend intends to try to do, then yes they could take those ones back.

Me: So why the conflict exactly?

Adam: LL use a set of proprietary components in their official release, for example the Kakadu JPEG2000 library - which means their official release is actually GPL-incompatible. RealXtend have to extract out any bit of Linden IP or derivative work in order to be able to release it under a more permissive license. (The GPL is actually fairly restrictive). In copyright law, you can generally make a open source license more restrictive, but never the other way around - it’s one of the reasons that OpenSim is licensed under one of the least restrictive Open Source licenses. If LL took the GPL’d code RealXtend had done back, they would be under the terms of the GPL via RealXtends IP.

Me: So taking the client code back could cause problems?

Adam: Well, if they took it - yes. But unfortunately they really can’t. They could in their pure-open-source release, but not in their mainline release.

Me: What do you think is the best path forward re interoperability?

Adam: I think the best path forward for a standard is to release everything to either the public domain, or as close as you can get. It allows all parties to use the code for any purpose whatsoever.

Me: So you mean no GPL no BSD?

Adam: BSD is fairly close legally - it’s effectively public domain with a “Don’t sue us” clause. There’s a small group of licenses which are essentially public domain:
- New BSD (what OpenSim/libsl are under)
- MIT
- X11
and a few others.

Me: Can Linden Lab switch from GPL to BSD?

Adam: They can - as far as I know they have never accepted anything into their codebase which would prohibit it. They have been discussing lately switching a few key files to BSD, which would definitely be appreciated - but the whole client would be better. A lot of people do - I’m not going to go into names (you can if you want), but there’s a fairly large group of people who dislike the GPL. At least for this kind of standards setting thing.

Me: So what is the road map for OpenSim now? What do you see as the 3 month goals to be, and then 6 month and then one year?

Adam: 3 month goals - we’re going to try and align the two codebases we have now into one seamless codebase that works well both with the official SL client, and with the improved Realxtend one.

We’ve also got a few short term goals in terms of stability, getting features working properly, and maybe with a little luck, doing a bit of work on our client networking. Of course - anything I say has to be taken with a grain of salt, open source means people can work on what they like effectively.

In six months time, I’d like to have the majority of the features in the official client supported, and to be reasonably stable enough for large scale deployments.

I think that might take longer than 6 months, but you never know.

A years time, I’d like to be working towards next generation features - what sorts of things we think the standard virtual world must support, better support for linking environments has to happen over the next year - and we definitely need to be well on our way towards a really good standard infrastructure that can scale to the size of the web today.

Me: Re the discussion of standard features - what do you think is the best forum for this discussion? And, has realXtend committed to more development?

Adam: They have committed to working on this until their backing runs out, but it sounds like they might have found a way to continue working for a good while yet.

Me: And, the forum for the discussion of standards - what do you think is best for that?

Adam: I think that’s going to just happen on it’s own.

A lot of the standards bodies that have been setup seem to be moving no-where, and while we are all happy to participate in them - I think more is going to be achieved by doing things, testing them, seeing what works.

Me: And sorting out a more permissive licensing situation seems like it would help?

Adam: It would help - because it means we don’t need to spend so much time reinventing the wheel. We have to reinvent everything LL has done to be able to license it permissively.

Adam: The Rex serverside changes - those are all BSD, and we’re incorporating it back. Their viewer changes - those are GPL’d by necessity, and we’re not touching those. The RealXtend company has two different companies working on it to avoid any IP contamination. The serverside stuff was done by Admino, and the clientside by Ludocraft.

We’ve got two pieces of software here:
- OpenSim
- Rexviewer
and the server side changes to list them are the avatar server and….. and all the meshes etc. are on the client side with Ludocraft. The server side changes are things like the Python scripting, backend support for the meshes, avatar server, etc. The client side changes are the new rendering engine, client side mesh support, shadows, improved lighting, etc.

Me: Does Windlight goes out if Rex comes in?

Adam: Yes, Rex are looking at integrating Windlight properly into their viewer at the moment. But they can integrate that in without too much of a problem because that’s strictly a client side thing, and that’s already GPL’d.

Me: My friend Ben Goertzel of Novamente who is developing Artificial General Intelligence projects in VWs wanted to know if the skeletons allowed “the ability to script fine-grained control of skeletons controlling characters of different types.” He wants to control characters via inverse kinematics not just by launching pre-fab animations because without that you can’t have naturalistic or adaptable motor control. Will the mesh avatars allow that sort of thing?

Adam: IK is on RealXtend’s feature list - they haven’t implemented it yet, but they are working towards it. What your friend might appreciate is that you can have completely customised bones under the realxtend avatar.

The default skeleton has 220 bones in it, but you can make your own custom skeletons for things like anthropomorphic avatars.

One of the avatars we got shown was someone wandering around as a giant collection of mushrooms.

Me: Can you control the angles of motions of the joints?

Adam: Yeah, you can.

Me: Cool! Ben is going to be so happy. AI just moved a big step forward!

Adam: Shiny.

Me: Ben also said if I want to stress you are ask if you can implement realistic physics of fluids for him

Adam: We’ve got a physics engine that supports it, but client will take a lot of work!
