Multiplicity

Moving in front of the sculpture modulates the reflected light. It looks as if people are themselves ligths, their color shining on the triangualar facets on the wall.

Commission

Multiplicity was commissioned by Vallensbæk Municipality for their new combined service center, public library and citizens' house.

In collaboration with obscura (dk) I proposed a sculpture consisting of a physical object, folded from laser-cut steel, a couple of projectors, a Kinect and a computer.

The sculpture acts as a platform for interactive software artworks, the first permanent artwork, Multiplicity, becoming just one of the ways to reflect the citizens' movements in their new house.

Technical Approach

The software started as a fork of Kyle McDonald's ProCamToolkit, extended for a dual-projector setup with heterogeneous optics. It combines Kinect-based tracking with Mapamok's projection mapping calibration — a tool for solving projector position from correspondences between a 3D COLLADA model and projected points. Written in C++ with openFrameworks.
