Voyagers [openFrameworks]
Created by The Light Surgeons for the National Maritime Museum in London, the installation “Voyagers” engages with England’s long standing relationship to the sea, featuring thematic images and film from the museum’s collection animated atop a continually flowing ocean of typography across an abstract wave shaped structure. Together with a number of other projects, the installation opens to the public tomorrow. We got a chance to take a sneak peak earlier today and get some insight into the making together with what we enjoy most – the debug info and some fantastic behind the scene images.
James George from the New York studio Flightphase collaborated with TThe Light Surgeons to create custom application to animate the content in realtime. Created using openFrameworks, the applications use a number of different tools to communicate the narratives. The ocean effect of type sweeping across the installation surface is a 3d wave simulation created using a vector field. The complete simulation is stitched and mapped across seven projectors covering the 20 metre triangulated surface. The image sets were designed by the Light Surgeons to relate each of the six themes of the museum. openFrameworks parses the layouts and generates animations that cascade down the wave. Also, at the far end of the gallery is a Puffersphere, which is an internal spherical projector. During the course of each cascade of images the puffersphere collects thematic keywords that relate to the images and prints them onto the surface of the globe. Likewise, the type waves trigger projected content of the sphere as they “hit” it’s surface. The audio created by Jude Greenaway is mixed dynamically by interfacing openFrameworks to SuperCollider over OSC.
James used Dan Shiffman‘s Most Pixels Ever library for synchronizing the application. He has also released a number of changes to the library that can be found here (github). The team has also built a way to synchronize parameters over the network using MPE – github and through developing content for the Puffersphere, the team created a lightweight library for animating the surface of the sphere and can be found here.
