Laterna Magica

16 nov 09 - 28 nov 09
Keywords: State of the AR, Laterna Magica, Machine Mediated Vision, Head Mounted Display

This cube constructed out of black and white boxes simultaneously holds the past and future of vision machines. The boxes on the outside form a 2D-bar-code pattern which trigger a huge virtual artwork when viewed by a visitor wearing special virtual reality goggles. On the inside of the box a red world full of priceless old pre-cinematic devices are giving visitors a glance into the way people saw the world 200 years ago. Magic Lantern Museum in Scheveningen provided their collection for this installation. The realization of this installation was in close cooperation with Henk Boelmans Kranenburg, Bas de Boer, Melissa Coleman and Ferenc Molnár.

Work in progress The walls of the cube are standing. Painting about 250 boxes black. Piling the boxes. The Laterna Magica cube is ready... While watching at the black/white pattern with the goggles a virtual world is seen. On the wall-side there is an opening to the inside of the cube. In contrast to the clean b/w design of the cube the inside is deep red, furnished with pre-cinematic vision-machines from 200 years ago. These are all very delicate and antique mechanical slides for the magic lantern. These mechanical slides -made of painted glass- can be seen as the ancestors of the computer-animation A projection of a static version. A Showcase with objects from the pre-cinematic era. a magic lantern with a carousel<br /> a porcelain relief-landscape with light behind it In the corner a praxinoscope and next to it a zootrope. A stereoscope with perforated illustrations. More or less the same effect as the 3D-movie. The one with the mirrors is called a praxinoscope... ...and the one with the holes on the side is called a zootrope The magic lantern on the left is still used for performances. Back to reality...

Spectator 1.0

16 nov 09 - 28 nov 09
Keywords: State of the AR, KABK, AR+RFID Lab, TU-Delft, Augmented Reality, Robotic Vision

This automated visitor is a mannequin transformed into a robot. The dummy is wearing goggles with which 3D-images can be seen as projections over the real world. A camera in the headset captures the black and white paintings and a computer program translates these to 3D-images which are projected on a wall behind him. This way one can witness both the real world and the virtual combined as if one is looking through the eyes of a robot. This installation was realized in collaboration with the AR+RFID Lab, Bio-Robotics Lab - TU-Delft 3ME, Xavier Amoros, Yutaro Takahashi and Wim van Eck. The visual-code-paintings where executed by fine artists Erik van de Belt and Halbe Nicolai.

RFID Timeline

16 nov 09 - 28 nov 09
Keywords: State of the AR, AR+RFID Lab, RFID, FabLab

The interactive time line is a new way of retrieving and showing activities of the last three years of the AR+RFID Lab. This system allows one to physically interact with digital documentation. The RFID-tags (wireless identifying chips) give visitors a handle into a digital database. Each event is reduced to a moment in time and a number. Only when the visitor gives the archive event his attention does the richness of that past moment erupt when the machine speaks its story and beams its visions. This installation was realized in cooperation with Marcel Kerkmans, Melissa Coleman, Wim van Eck, Diederik Voortman and CabFabLab.

3D Pop-Up Book

24 Oct 08 - 4 Jan 09
Keywords: Sgraffito in 3D, Augmented Reality, AR-Toolkit

The 3D Pop-Up Book is an elegantly printed, large format book of poetry complementing the iconography of the sgraffito protagonists with writings and music of its time. When held before a web cam the book becomes the interface for medieval soundscapes and animations of the 2D carvings moving out of, then back into, its dish in 3D. Curator Historic Design Drs. Alexandra Gaba-Van Dongen and medieval music expert Margot Kalse chose the texts and music on the basis of their research into the iconography in the context of the Sgraffito in 3D project. The 3D-animations were realized in collaboration with Mit Koevoets.

Reconstruction Lab

24 Oct 08 - 4 Jan 09
Keywords: Sgraffito in 3D, Augmented Reality, 3D-printing, Rapid Manufacturing, AR-Toolkit

What if archaeological objects could tell you about their history? Imagine holding a 3D-printed shard of pottery in front of a web cam, which then reveals to you how it was once whole, that it got broken and then later was reconstructed. In Reconstruction Lab the archaeological pottery tells visitors about its history. By holding a 3D-printed shard of pottery in front of a web cam it reveals to you its missing pieces. The 3D-printed shard acts as an interface for the virtual object: when you move the shard in your hand you move both the physical and virtual object simultaneously as if it were one object. This installation was realized in collaboration with Frank Berg and Wim van Eck of the AR+RFID Lab.

3D Archive

24 Oct 08 - 4 Jan 09
Keywords: Sgraffito in 3D, Serious Gaming, Unity3D

What would a virtual 3D-archive of digitalized cultural heritage look like? The archive, its design based on the kind of pits in which many archaeological discoveries are made, collects virtual objects which can be summoned from the depths. The objects can be virtually manipulated, broken, put back together and can be downloaded online for one’s own purposes, such as 3D-printing, study of the object or as a part of one’s own 3D-artwork or archive. A simplified version of the Unity3D program was exported to the web at sgraffito-in-3d.com.

Protagonist-Antagonist

24 Oct 08 - 4 Jan 09
Keywords: Sgraffito in 3D, Rapid Prototyping, Rapid Manufacturing, 3D Printing

Seven protagonists of the sgraffito earthenware collection of van Beuningen-de Vriese were copied through the process of 3D-scanning and 3D-printing. These clones, the antagonists, were placed in front of the archaeological objects. In a break with tradition, visitors could take these objects in their hands and with their fingers follow the traces drawn half a millennium ago while looking through the glass of the vitrine at the real untouchable object. The 3D-printed clones thus mediate the archaeological objects through tactile feedback.

Keywords: Sgraffito in 3D, Computed Tomography, Medical Imaging, Digital Heritage

Twenty-two objects from the sgraffito earthenware collection of van Beuningen-de Vriese were scanned with a CT-scanner. The CT-Scan video is an artistic interpretation of this process. The visitor follows the path of the CT-scanner as its X-rays move through the object without destroying it and allows the visitor to see an object on the inside through the eye of a machine.

Sgraffit-o-matic

Mar 08 - Apr 08
Keywords: 3D Milling, Sgraffito, .ekwc

A 3D-milling machine is programmed to draw a design in a wet clay tablet using the sgraffito technique. Sgraffito (also known as slip carving) is a traditional decoration technique -used to decorate ceramics- in which a top layer (engobe) has designs scratched into it, revealing the layer of red clay beneath. This technique was used in Holland in the late middle ages (1450 to 1550). In drawing, the machine reveals a logic of its own, which is alien to the way a human would.

‘Oorsprong’

Mar 08 - Apr 08
Keywords: Interactive Installation, Artist in Residency, .ekwc

‘Oorsprong’ is an interactive installation commenting on the relationship between the model and the serial object. A mass-produced object becomes an artwork in the process of personalization. In the context of the Sgraffit-o-rama project for Museum Boijmans van Beuningen I have had a residency at European Ceramic Work Center (.ekwc) in Den Bosch, The Netherlands. Although I did some sculpting at the art academy I had never worked with clay before. The .ekwc gave me the opportunity to learn all about ceramics, moulding and casting techniques. The slides below show the making process.

Céramique Électronique

Jun 07
Keywords: Robotic Ceramics

‘Céramique Électronique is the working title of a proposal for Robotic Ceramics. The concept concerns the transformation of archeological objects into robots as a way to show the ceramic collection in a cultural historical perspective. A fully automated reconstruction-technique is suggested by applying electronmechanical technology to an archeological object. Parasite Archéologique: A hydrolical spider transforms shreds into a vase. This proces is initiated when a visitor is in the vicinity of the object. The ceramic robot reacts as a living creature. As if it were an insect quickly trying to hide.
