Concrete forest

Concrete Forest – an art project that turned into a party from Obscura on Vimeo. The video shows the result of a fun little project we did in collaboration with artist Louise Bech Pedersen. We cut out these animal figures of a special acrylic rear projection material and used them for mapping using Modul8 and MadMapper. Doing the mapping was trivial using these tools – it was the acrylic material itself that proved to be a bit of a challenge. The light projection properties of the material were terrific, a clear and bright image from all angles. For people like us who are used to projecting onto fabric or walls it was a joy to see the brightness of this professional screen material. However the material was a quite brittle and cracks appeared a few places even when using a saw made for use with acrylics. And the deer lost […]

Using Unity3D for mapping

The above video documents a recent project Obscura did. Actually I was mostly on another project at the time but I followed with great interest the work that my colleagues Frederik and Kasper did here. For all of us this installation was a learning experience in using Unity 3D for mapping onto a spherical object. It took a bit of trial and error but Frederik and Kasper decided to make a workshop out of it instead of worrying too much about the finished result. They ended up with these little creatures created in Open Frameworks which were piped into Unity 3D via Syphon. They then made a Unity app for mapping onto the sphere. A regular 3D mapped rendering would not do here, as the small boids react to the presence of people in the room via a motion tracking camera. Using Unity went resonably well – it has a […]
