Geometry Lab – register now!

Trick Eye, Zometool, Shadowing: Geometry Lab – the 3D festival in the Ludwig Forum invites you all to dive into the fascinating world of geometry. With science to grab hold of and 3D printers to go. Three whole days – don’t miss out!

The golden ratio and one-point perspective, star charts and GPS. The real world and depictions of it are based on the laws of geometry. Geometry is a common foundation and common language for vast areas of science and art. Reason enough for Leibniz Prize winner Professor Leif Kobbelt and the Ludwig Forum to get together and stage a Future Lab project event: the 3D festival “Geometry Lab”.

An important part of the festival are workshops. The absolute highlight will be a workshop with Leif Kobbelt and his team. Together with the workshop participants, they will build working 3D printers. Register now!

Paper Folding
In this workshop, which will take place three times in all under the supervision of the artist Rinus Roelofs, participants will learn to fold carton and into fascinating geometric forms and aesthetic constructions. Similar workshops have already caused a sensation from Japan to the USA, for example in the Museum of Modern Art in New York. Folding templates and materials will be provided.

Supervision: Rinus Roelofs, Geometry artist and mathematician from the Netherlands –

Zometool is a geometric toy with which you can put together complex lattice structures and polyhedrons. In this workshop, participants will work together to construct a huge model with way over 1000 parts. Construction materials will be provided.

Supervision: Erwin Kotzab, Manager Zometool Europe

3D Printer To Go
In just three hours! Under the supervision of 3D printing experts, participants will build their own 3D printers. At the end of the workshop, each participant will be able to take their printer home with them.

Supervision: Prof. Dr. Leif Kobbelt & Ole Untzelmann
(Visual Computing Institute, RWTH Aachen)

3 – 5 November, 2017
daily 10 am – 5 pm

In a compact exhibition, works of art will meet scientific exhibits. The event will make use of everything from building blocks and mirrors to computers and VR headsets. The idea is for visitors to get an impression – through hands-on experimentation with objects – of the complete spectrum from classical geometric constructions to current geometry research. The show will also feature an exhibit that is created before the very eyes of the visitors. The famous 1.66-meter-high “Supermarket Lady” by Duane Hanson will be printed out live – in 3D and in original size!

Sun 5 November, 2017
10.30 – 12 noon

What is geometry? What importance does it have for science and art? And what role does it play in everyday life?
Experts give answers in short lectures:
Dr. Andreas Beitin: “Das Digitale und die Kunst — Interaktive und netzbasierte Medienkunst. Kurze Fassung einer medialen (Vor-)Geschichte” (in German)
Rinus Roelofs: “How Art Can Help to Understand Mathematics” (in English)
Prof. Dr. Helmut Pottmann: “Architekturgeometrie” (in German)
Prof. Dr. Leif Kobbelt: “Geometrie 4.0” (in German)
Moderation: Bernd Büttgens

On all three days volonteers guide you through the world of geometry.
