![]() You can make your own by covering walls and windows with black Molton ![]() The first successful deployment of this technique was in 2009, with the scanning of the complex, 3D web of the black widow spider.aĭark room, 5 x 10 metres. This technique has since been developed and refined in cooperation with a number of other scientific institutions. The successful technical development of this technique was then realized in collaboration with researchers at the TU’s Photogrammetric Institute.įrom a two-year collaborative research effort to address this question, Saraceno pioneered the Spider Web Scan technique: a scientific method combining laser supported tomography with photogrammetric analysis, to allow the 3D-scanning of a spider web. ![]() After exploring a number of different methods that proved inadequate to the task, Saraceno proposed the use of a sheet laser to illuminate and scan complex spider/webs. As the experiments progressed, the collaborative dialogue also grew, enrolling the expertise of Samuel Zschokke (University of Basel) in web construction and evolution, and Christof Wulff (Technische Universität (TU) Darmstadt, Germany) in photogrammetric capture techniques. On Jäger’s suggestion, Saraceno focused on the web of a black widow spider ( Latrodectus mactans (Fabricius, 1775)) – chosen because of the relative availability of this spider, and also for the large, complex 3D web that it weaves.Įarly efforts to create a 3D scan of this web using existing scanning methods proved unsuccessful – as the unique properties of spider silk (the fineness and reflective qualities of the threads) made it unsuitable for capture by conventional approaches. The setup also proposed an optimized automated capture system, and improved image processing and image-to-line algorithms.įrom this initial question, Saraceno began a conversation with arachnologist Peter Jäger (Senckenberg Research Institute and Natural History Museum, Frankfurt am Main, Germany) to explore the possibility of creating a 3D scan of a natural spider web, and using these data to reconstruct a large-scale model of the web for an art exhibition. In this setup, a green sheet laser (532 nm) is used to illuminate 0.5mm slices of a 3D spider web housed in an open carbon Spider Web Frame. The most recent iteration of the Spider Web Scanner proposes a more automated setup of the original method, and was developed in collaboration with MIT’s Laboratory for Atomistic and Molecular Mechanics, led by Markus Buehler. 2D images (x, y coordinates) are then processed to generate a 3D data model of the scanned web, via a Spider Web Digitization process, which can also involve manual reconstruction of dense and complex sections of the web. A sliding sheet laser (original setup: red laser, 650 nm) is then used to illuminate vertical slices of the 3D spider web, and 1-2 high-resolution camera(s) used to capture stereoscopic images of illuminated web sections. Spider webs to be scanned are first built by the spiders in a carbon Spider Web Frame structure designed by Tomás Saraceno, with advice from arachnologists Peter Jäger and Samuel Zschokke. It supports CGI, frames and other languages beside HTML, for instance PHP, Perl, C++, Java, and JavaScript development.The Spider Web Scan is a laser-supported tomographic method created by Tomás Saraceno in collaboration with the Photogrammetric Institute, Technische Universität Darmstadt. The output of the code can be previewed in up to six different web browsers. The program can import and convert to HTML various RTF documents, tables and outlines from any Windows 95 (and above) compliant application. The program was licensed as Careware software, then as LGPL-2.1-or-later in 2011, and now as GPL-2.0-or-later since 2018 with the source available on the website. Arachnophilia requires the Java 2 runtime environment, release 1.5 or later. Once written as a Windows application, the program was rewritten by Lutus in Java as part of his boycott against Microsoft and its product activation features for Windows XP. The name Arachnophilia comes from the term meaning "love of spiders", a metaphor for the task of building on the World Wide Web.Īrachnophilia is free and open-source software subject to the terms of the GNU General Public License. ![]() It is the successor to another HTML editor, WebThing. Arachnophilia is a source code editor written in Java by Paul Lutus.
