Public Lecture on Leonardo’s Elevated Polyhedra - Models by Rinus Roelofs

Rinus Roelofs will give a public lecture on his research on the integration of design and art with digital sculpture and 3D printing on which he is regarded as an international expert.


Stellation is a well known operation which you can apply to a polyhedron. About a century before, this operation was defined by Kepler, Luca Pacioli and Leonardo da Vinci had published the book “La Divina Proportione” in which another operation, called Elevation, was described. Both operations have much in common, but there are also many differences. The elevation operation as described by Luca Pacioli and Leonardo da Vinci turns out to be a big field of inspiration, which leads to many interesting constructions, esthetic as well as constructive. Comparing Elevation and Stellation inspired Rinus Roelofs to define a new one, which he called Edge Elevation. Besides on spherical patterns, the Elevation operation can also be applied on cylindrical patterns and flat patterns. This all leads to interesting artistic constructions. Also because the resulting structures are double layered, at the moment he is investigating the possibilities of the double weave with these double layered structures.

About Rinus Roelofs 

Rinus Roelofs was born in 1954. After studying Applied Mathematics at the Technical University of Enschede, he took a degree from the Enschede Art Academy with a specialization in sculpture. His commissions come largely from municipalities, institutions and companies in the Netherlands, but his work has been exhibited further afield, including in Rome as part of the Escher Centennial celebrations in 1998. From 2003 he is a yearly presenter at the Bridges conference, a conference on connections between art and mathematics. Since 2102, he has been teaching mathematics and computer drawing at the University of Leuven, department Architecture in Gent (Belgium). In May 2014, he joined the exhibition by Ars Mathematica on “Materials for Inventions” in the School of Design of the Hong Kong Polytechnic University as a guest artist.

About Ars Mathematica

Ars Mathematica is an international non-profit organization, founded in 1992 in France by Christian Lavigne and Alexandre Vitkine. It promotes the encounter of art, science and technology, particularly the research related to digital objects in the electronic arts and the development of 3D and digital sculpture (or "cybersculpture").
