Teleporting between  Virtual Worlds

‘Seamless, intuitive and immediate’

travel  between OpenSims

The future  is here:  a seamless virtual world environment where one can teleport  transparently between any OpenSim virtual world  – no not SL yet but wait for it –  no matter what the OpenSim virtual world is and where in the real world it is mounted.

If it lets you in and door is open you will be able to teleport there.

Zonja Capalini referred to  teleporting between OpenSims via hypergrid  in her comment and video on THE ‘OPENSIM’ EXPERIENCE – Worlds of difference but ones that Kiwi developers should probably try out but now  OpenSim boundary crossing was given the imprimateur  of  the mainstream virtual blogging community  by  virtual world guru Wagner James Au (pictured right) (SL: Hamlet Au) in NewWorldNotes  last week.WagnerJAu

Au described it as a “milestone breakthrough”  following the Second Metaverse U  conference(Stanford University) demonstration of Science Sim, the Intel-backed, OpenSimulator project linking a number of 3D science experiments into an interconnected network.

The ” exciting” and “jaw dropping” event was presented by  Tom Murphy, professor of computer science at Contra Costa College in San Pablo, Ca

“In the demo,”  Au said, “Murphy ran an OpenSim viewer on a big video screen, teleporting from a science project running on sims located in Oregon, to another in Utah, to another at NorthWestern University in Illinois, and back again. From the viewer’s perspective, the teleport procedure looked exactly like it does in Second Life, except instead of TP-ing from one part of the grid to another, Murphy was going from one private cluster of OpenSim servers to another.

“The process was seamless, intuitive, and immediate,” Au said.

“This strikes me as a profound innovation,” he said. “From an avatar’s prospective, it’s now possible to travel from private OpenSim sim to private OpenSim sim in a way that’s indistinguishable from Second Life.

“Of course, teleportation of virtual money and assets is another question, but for metaverse experiences which don’t require those, OpenSim is now a viable alternative.”

Au noted that the teleportation code had been created by Cristina Videira Lopes (pictured right) (SL: Diva Canto), Associate Professor in the School of Information and Computer Sciences at the University of California, Irvine. Prior to joining Academia, she worked at the Xerox Palo Alto Research Center.  She is co-inventor of AOP (Aspect Oriented Programming), a programming technology featured in the MIT Technology Review (2001) as “one of the 10 emergent technologies that will change the world.”Cristina Videira Lopes

She’s also the visionary behind OpenSim’s hypergrid, which Au and Capalini have  previously written about.

Maria Korolov commenting on Au’s report said  that on OpenSim residents had been  happily using hypergrid teleports for some weeks now. For example she recently took her avatar shopping at OSGrid (picked up a free hot tub) and took  it back to her standalone grid, and installed it there.

Assets transfer fine, including clothing and hair and inventory,” she said. “I still have the same rights to them as I did on my home grid — I can’t give something that’s marked “no transfer” or copy something that’s marked “no copy.

“If I make a backup (by saving an OAR) file I will have a copy of all the assets that are on that region. for the purposes of restoring them later if something happens. If I distribute that OAR to other grid owners for them to load up on their grids, I will be violating the IP rights of the producers of my assets — same as if I made a backup of a computer program and then distributed it.

“So we already have cross-dimensional shopping.  Currency is still an issue — it would make more sense to keep currency in an on-grid account, rather than with your avatar. For example, if you go to a website that gives you credits, those credits aren’t stored in a cookie, but in a secure database owned by the website.

“That way, when you go from one website to another, the money doesn’t go with you — it stays where it’s safe.

“Or one can use PayPal or Google Checkout, which  can use on OpenSim as well,” she concluded.

All I can say: The whole wide world is waiting out there, baby! Well virtually anyway.
