beta 6 is out with a lot of important features:
in november we had our second review of the iTACITUS project. therefore i finished an augmented reality applications for winchester castle’s great hall. it shows overlay information about three points of interest: arthur’s round table, the court and an outside scene with the sheriff of hampshire.
the main task was to present these scenes on the sony ux ultramobile pc. additionaly i showed the outside scene on the iphone with my snapshot augmented reality application.
the project finishes in may 2009.
it works amazin accurate! download instantplayer and open the file to test it. next i will put it into a proto for better integration.
yvonne added a PaintTexture for debugging: jsgestures.zip
“snapshot augmented reality” on iPhone let’s you take a photo and augmented it with virtual objects or geolocated information. therefore the application sends the image to InstantVision server via Wifi or UMTS. the overlayed image is sent back to the iPhone and displayed some seconds later.
this lightweight solution eliminates the major problems of augmented reality on mobile devices: hardware availability, computing power and battery life. and it is compatible with Apple’s iPhone SDK, where live video streaming is still forbidden. the client is a very slim application that takes a photo and sends it to an InstantVision server. this server extracts the geolocation of the image and runs a database-driven postertracking on it to calculate the iPhone’s camera pose. therefore a reference image and a prepared 3d scene of each point of interest (POI) is needed. a flickr image and a small X3D scene is enough.
due to the distributed architecture the slim client can be ported to android, symbian, etc.

the presentation of the paper â€œAdapting X3D for Multi-Touch environmentsâ€ at WEB3D conference and our demos at the WEB3D showcase were really successful. tobias showed his mixed reality light simulation and i presented the radiohead iphone experiment.
at SIGGRAPH johannes and dirk gave their “Don’t be a WIMP” class. we showed some stereo rendering, wiimote 6DOF and augmented reality demos afterwards. inbetween we had to run to fetch the google t-shirts..
next years WEB3D conference will be at IGD in darmstadt!
yesterday we arrived in LA. it’s curious how familiar i am with the town from playing GTA San Andreas.
today i gave my talk at WEB3D conference co-located at SIGGRAPH: “Adapting X3D for Multi-Touch environments”
we are about to release our x3d player for the iPhone! patrick just finished the OpenGL ES based application today. it is build with the official iPhone SDK and will be available in the AppStore soon.
beta5 of instantplayer will be released today, too. the experimental BrowserTexture is one of my favorite features. XMLHttpRequest was postponed to beta6. meanwhile i found a solution via TCPClient backend for loading and parsing XML.
all news and interesting demos will be presented at WEB3D and SIGGRAPH next week. see you there..
2. the Thom Yorke Hologramm video was seen over 18.000 times on youtube and is the second highest ranked in Radiohead’s youtube group after their own video
4. instantplayer beta5 will be released soon with one of my favorite features: BrowserTexture – display interactive webpages on a texture
5. my students finished their projects: minimal interfaces
johannes helped me with the calculation of the dynamic grid formula:
x elements = squareroot ( number of images * aspect ratio )
y elements = number of images / x elements
code example (HelloInstant.py):
from java.net import InetAddress
from vrml import *
Â Â Â Â Â address = InetAddress.getByName(“localhost”)
browser = eai.BrowserFactory.getBrowser(address, 4848)
Â Â Â Â print(browser.getName())
1. just download and install jython:
2. put you instantreality lib (instantreality.jar) into java classpath or modify the startup file (jython) in order to do so:
# This file was generated by the Jython installer

if [ ! -z “$CLASSPATH” ]
“/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Home/bin/java” -Dpython.home=”/Users/me/jython2.2.1″ -classpath “$CP” org.python.util.jython “$@”
3. start the python file in your shell:
