Here is a short AR improvisation:
The ease of using ARive made it possible for me and my girlfriend Sølvi (of Hvitsnippforlaget) to drink a bottle of wine. After doing so, Sølvi had the great idea of augmenting a Norwegian national gown. Why? I do not know. But we made the whole thing (including video-editing and publishing) in 30mins.

Progress for the people!

To my friend Kjetil at www.ka-d.net

Thank you for the invaluable support on ARive!

-Kjetil encouraged me to implement the ODE-physics motor in ARive. I’ll never get around to this before the semester ends, however, ARive supports direct export from MAX of simulations made with the Havoc engine.

This is a late-night quikie especially for you!

Here is the proper link for OpenSceneGraph Max Exporter on Sourceforge:

http://sourceforge.net/projects/osgmaxexp

-This is the definitive tool for me, creating content for ARive; it fluently exports maps, lights, particle systems et.c, with an OSG-preview window.

OpenSceneGraph Max Exporter is the fabulous work of Joran Jessurun and Hartmut Seichter.

The GUI is coming along fine, with lots of great input from my Visual Communication teachers, and not to forget, my invaluable friend Ove Sveumshagen (IT Advisory Specialist) who worked out how to fix my string-to-terminal problems. Cheers! Next round is on me!

Anyways, here is some test-footage of Virtual Furniture:

Content Featuring:

  • Model of Scandia Junior exported directly from 3DMax9
  • Point-Grey camera in action, 640×480 15FPS (far from optimal)
  • 50.000 poly’s (this is overkill, to test out general performance)
  • 2.4 MB total worth of textures
  • Texture baking
  • Environment maps (simulated reflections on the base of the chair)
  • Shadow mapping (opacity map from baked texture)
  • 60 FPS rendering (not visible, video recorded at 15FPS)

Bad stuff:

  • Model (and whole video) appears a lot wider than it should, due to my ineptitude at video capture.
  • Textures are a bit over-exposed, due to me forgetting to normalize the maps before baking them.
  • Environment map not really looking any good. -Still experimenting…

Also thanks to Prof. Høgset for tipping me about the FLV-embedder for wordpress.

Here is a more complex kind of content, that I did not think would be possible until I discovered I could use Flash to develop an interface for ARive, thus opening for online-integration with SQL.

Graphitti is illegal as an artistic medium here in the capitol of Norway, with the police enforcing a zero-tolerance policy.

Virtual Graphitti is an online ar-service that works as follows.

Content:

Artists can log on to a website, i.e. www.formbureauet.com, and register themselves anonymously.

With this account, they can upload a 3D-model and link it to a marker on the site.

After that, they can print the marker on a sticker, and place it anywhere in Oslo. = Legal, no policy against stickers.

Alternatively, they could draw or spray the marker by hand on any location.

Audience:

Using a smart-cell phone, people discovering the markers around town, can do one of two;

1. Take a photo, and send it to wap.formbureauet.com, and get a new photo in return, displaying the model superposed on the marker.

2. Download a portable version of ARive on their phones, and watch the virtual graphitti in real-time.

This is an extension of Virtual Spaces, but perhaps even more traditional AR-use:

High-def models of design-furniture, are linked to a marker, that can be placed in an appartment.

An easy and intuitive way of seeing how refurnishing you place could turn out. Move the marker-move the furniture.

I will cooperate with my brother-in-law Pål Lunder of fjordfiesta furniture to display some pieces of the Scandia-chairs (by Hans Bratterud).

This is a beautiful example of Scandinavian design, and I’ve already done the 3d work for the Scandia Junior chair.

Not original in any way, but necessary to use ARive in an architectual context.

I want to use markers in a physical environment to introduce new structures, or mask out existing ones.

On the experimental side, I would like this to encompass “impossible perspectives”… I’ll post some more sketches soon.

Unfortunately i need Occlusion for any of these to be really interesting.

This is an idea for a kinetic sculpture, inspired by the works of Alexander Calder.

It is a branching structure, resembling a SceneGraph itself, with the _root at top, hooked to the ceiling.
At the end of each branch is a “node”, with a marker.

This physical installation is to hang freely in a room, while a camera or a head mounted display will allow an audience to either watch it, or interact with it.

The installation will react to the physical enviroment in terms of small local winds in the environment, causing it to rotate, or spin the nodes.

Virtual Objects attached to the nodes, will then flicker in and out of appearance, and move parallel to the physical object.

This could be video, or models, either attached close to or over the markers, or distanced from them, moving, appearing and disappearing across the room.

I like how this could explore the relation between physical/virtual, and how it also represents an interface on many levels:

It is a representation of the scenegraph, but also takes input from wind, but not with a anemometer/wind gauge, but a camera.

Here is a rough sketch:
