SurveillanceSaver will run as a multi-touch application on the new heyewall 2.0 with a 35 megapixel resolution. the whole database (> 1000 images) will be displayed as a grid of images.
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
one of the nicest scenes of SurveillanceSaver is the barn of a pig in england. it has a family now!
jython also works for EAI (external authoring interface) for X3D browsers like instantplayer. this is a 5 minute proof of concept.
code example (HelloInstant.py):
from java.net import InetAddress
from vrml import *
address = InetAddress.getByName(“localhost”)
browser = eai.BrowserFactory.getBrowser(address, 4848)
print(browser.getName())
1. just download and install jython:
http://www.jython.org/Project/download.html
2. put you instantreality lib (instantreality.jar) into java classpath or modify the startup file (jython) in order to do so:
#!/bin/sh
# This file was generated by the Jython installer

CP=”/Users/me/jython2.2.1/jython.jar:/Applications/Instant Player.app/Contents/MacOS/instantreality.jar”
if [ ! -z "$CLASSPATH" ]
then
CP=$CP:$CLASSPATH
fi
“/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Home/bin/java” -Dpython.home=”/Users/me/jython2.2.1″ -classpath “$CP” org.python.util.jython “$@”
3. start the python file in your shell:
./jython HelloInstant.py
i am sure that if ben fry and casey reas would start processing today they would use python instead of java. learning the short and efficient python is much easier than the statically typed and lengthy java. no compilation would be necessary anymore, tons of native libraries would be available via c-bindings, etc. nodebox is a nice example of the use of python for computational design. unfortunately it is restricted to os x.
today we are using python for all sorts of automated code generation in wuerzburg. one example is the conversion of fluid simulation data into x3d files for our coperion project. jan and sebastian are using this approach for their simulated cities of their master projects.
i started a short proof of concept of a python based processing. jython is an implementation of python in java. with its help it’s possible to write code with the processing api in python language.
code example (helloProcessing.py):
from processing.core import PApplet
class HelloProcessing(PApplet):
def setup(self):
global p
p = self
p.size(350, 350)
def draw(self):
p.fill(p.random(255))
p.rect(150, 150, 50, 50)
if __name__ == ‘__main__’:
import pawt
pawt.test(HelloProcessing())

at fraunhofer igd i am leading the augmented reality part of the eu funded project iTACITUS. the project deals with mobile augmented reality for cultural heritage sites.
in april we tested our markerless tracking and my reality filtering system at the unesco word heritage site “reggia venaria reale” near turin in italy. the markerless tracking bases on alain’s and yulian’s poster tracker. you only have to take a reference image of the background for a stable tracking. that’s how tracking should work.
my reality filtering system renders the whole environment at a sketch in order to augment historic drawings on the site. one example is temple diana at the site. it was located at the end of a long creek in the large gardens. only its ruins and two historic drawings are left. standing on a viewing platform visitors are looking through the display of a mobile computer. as soon as they are looking at the temple’s position the video on the screen is rendered like a sketch and the drawing on the temple fits in the environment. the whole garden becomes a real time drawing.
there is a flash video of the tests on the project site:

ps: mark from boingboing just wrote about a frog concept about a reality filtering.
