WebTundra based VirtualOulu at Web3D Conference

University of Oulu’s realXtend Tundra & Webtundra based VirtualOulu environment was presented and analyzed at Web3D 2016, presented in late July in Anaheim, California. Article is in open access at ACM: VirtualOulu: collaborative, immersive and extensible 3D city model on the web

VirtualOulu has been in testing for long already, is hosted on Meshmoon and features Jonne Nauha’s early stab from a couple of years ago on kd-tree based scalable scene management, with prioritized asset loading etc. The test for measurements in the article is this walk from the market square to the cultural center near town hall:

3D Models in City Planning

realXtend is making it’s way into city planning processes.

The city of Oulu organized a seminar about 3D models in city planning (Finnish) on 16th March 2016 with a hall full of participants from architect companies & technology providers working with point clouds and other 3D models.

Timo Mukari presented how the city provides 3D models automatically from the official city databases. Jere Klami explored the possibilities with 3D models in participatory city planning. Tommi Hollström presented the MAPGETS application platform — based on realXtend’s WebTundra — which features automated generation of 3D cities from map and building databases. Toni Alatalo described Playsign‘s approach to utilize lessons from games to bring action structures on top of the models and showed the Playsign product for publishing city and building plans as game-like mobile and web apps.

The technologies are getting on-board to be actually utilized for city services and planning — stay tuned for updates we’ll post when actual end user applications come online!

3D Web & Open Data for Smart Cities using realXtend and Meshmoon

An intense week of realXtend based app development is going on here in Oulu now! As a part of the 7th Summer School on Ubiquitous Computing organized by the UBI (UrBan Interactions) research program, I and Cvetan & Koste from Adminotech are running a hackathon with prof. Ojala.


Focus of the hackathon is open Open Data and Smart Cities, and area with much activity around realXtend also otherwise:

  • EU’s FIWARE announced global Open Data activities at CeBIT 2015
  • the Finnish national 6Aika project is getting started and there’s a plan to harmonize on the realXtend open source base to get an open innovation platform for the cities in Finland (and hopefully globally eventually :)
  • Adminotech has good business going on with their smart city offering and the new Meshmoon Geo plugin.

realXtend in EU Future Internet initiative – 80M funding for application dev

Base technologies from realXtend, including the WebTundra HTML5 client, the Tundra server, and geographical information servers (POI, GIS), are now included in EU’s catalog of so-called generic enablers for future internet application development. Today, the EU FI initiative is launching an open call for app developers: a whopping >80M euros is there for startup businesses.

The launch for that app / web service dev funding is at the ECFI event in Munich, from Tue to Thu, and I’ll be demoing WebTundra and giving introductory workshops etc. there. There’s also a round of bootcamps coming around Europe in the coming weeks where our folks from Adminotech, Cyberlightning, Playsign and our German partners from DFKI will be coaching our 3d Web and related backend service tools.

For more info see the funding call at ECFI and WebTundra and other entries in the FIWARE catalog. Let’s start making good use of the technologies which are nice and mature now, largely thanks to WebGL and other browser efforts during the past years and the three.js graphics library — the time is now, with plenty of money available to help get started!

Cloud Party People – Welcome to realXtend?

Quite some news: http://blog.cloudparty.com/2014/01/24/a-sunset-for-cloud-party/

They provide Collada export so people can get their worlds / content.

Perhaps they can move to realXtend? This is a perfect example of downsides of proprietary techs, owned by a single company which can just get shut down like that. On open source, anyone and many hosting providers can run the worlds so this would not happen.

We are finally releasing Web client next week, WebTundra made with WebSockets + WebGL — like CloudParty is too — and WebSocket server integrated to Tundra. And friendly Meshmoon hosting, similar to Cloud Party but using realXtend, will feature 1.0 production quality integrated web client.

Interesting times! Also of course intriguing to see what Yahoo will do. But that will also be proprietary and closed, probably takes time too. Who knows perhaps interoperability etc. will be possible also with them eventually etc, with web and possible upcoming vw / 3d internet standards?

51 exhibitions in Berlin and realXtend

Berlin Gallery Weekend 2012 featured 51 new openings in galleries around the real city. Each exhibition is also publicly online using realXtend in Virtual Gallery Weekend — at least for this week still, so you have now a unique chance to see some interesting contemporary art pieces!

The same scene is available both with a Tundra client (‘full version’) and, for the first time for a real commercial realXtend service, with a browser based client using Flash and Away3d (‘light version’).

Do visit, and we are happy to answer any questions for example in the comments here! Virtual Gallery Weekend is a Spinningwire Ltd. project, in collaboration with Adminotech for the Tundra version and Playsign for the browser based one. The technology review leading to use of Away3d for this project was published earlier in Browser Based realXtend Client Technologies.

Tundra and Blender Integration demo presentation

The video from the realXtend presentation at Blender Conference 2011 is up, thanks to the conference organizers!

The picture is from a camera viewing the projected display, which was nice and bright with colours at the conference venue, but for some reason appears quite dark in the youtube video. Things do show and audio is ok so I hope this works as an introduction to Tundra overall. Features the Chesapeake Bay demo scene with little games, and finally the nice new Blender integration itself. There are other videos and docs about blender2ogre with actual usage instructions etc. by Brett.

Having the ‘magic button’ in Blender, that automatically runs the Ogre exporter and runs the scene in Tundra for me, has actually made a big difference: now just testing some old existing game prototype scene, made with Blender, doesn’t feel like much effort with the exports and all .. is just a click of a button. Workflow is the thing!
