Yesterday the New York Times as well as the Wall Street Journal published an article about a new motion capture device called “Contour” which was apparently shown at siggraph yesterday and which was developped by former Apple Computer engineer Steve Perlman.

Yes we did it: Finally there is a public jReality release (BSD license). jReality is a 3d graphics library written in Java. It is developed at TU Berlin, University of Munich and Citty College New York at the moment. it has already been used in several of our daytar projects like seidesein, ADDeye, or vitruman.

We put a new processing applet with the title “Mahrzipanien” on the daytar art page.

In the blog post “LaTeX and Metafont” two projects which massively scan in books were mentioned. Another mentionable project is the Gutenberg project. Here one can find e.g. the book of (more…)

99% of todays math literature are typeset with a typesetting language called “LaTeX”. There is basically no other way nowadays to publish mathematical texts in a decent form. In earlier times publishing mathematical texts was tedious. (more…)

It is sometimes interesting to observe how ideas breed. Since some years there has been Ken Perlins vision of a Laser-Leia – or err – a teddybear? – on his marvelous and famous homepage (-> which had been included in the Whitney artport!). Seems last year (more…)

we get hyperselfreferential to improve our google ranking :).

I.e. this is a follow up to the two posts “Journées Informatique et Géométrie” 2006 and to 3 from 2 (dimensions of course).— Or to put it differently: I couldn’t resist to try out the software mentioned in 3 from 2 (dimensions of course). As a matter of fact the software works brilliantly on minimalistic math buildings. In particular it turned the image of the Nautibus building on the Campus in Lyon in to a Potyomkin– Nautibus. Next time I try Roermond-Ecke-Schönhauser
(“corner of Roermond and Schoenhauser Strasse”).

Unfortunately the jReality filereader (I have nothing to do with this bear!) has sofar no VRML2.0 parser, so I had to use Xj3D, whose navigation is mildly speaking “uncomfortable”. Stay tuned for the parser and in particular for the upcoming jReality release!

At Carnegie Mellon the group around Alexei Efros developed a technique to reconstruct 3d data from a single outdoor 2d image. With impressive results.
