Video mapping is a popular technology in the multimedia industry and is not perceived like magic anymore. Known as spatial augmented reality, it is meant to transform still objects into surfaces for video content. However the objects don’t necessarily need to be still anymore – mapping on kinetic surfaces is the next big thing in the history of this technology.
February 15, 2018 marked the first time when interactive media production studio Sila Sveta presented a multimedia show with 3D projection mapping on volumetric arrays controlled by kinetic winches. The project was created in partnership with Departáment agency for the Russian premiere of the new Lamborghini Urus.
3D Projection Mapping and Mixed Multimedia
On this day, the world’s first Super Sport Utility Vehicle from the legendary Italian manufacturer was introduced in the Museum of Moscow. For the main show Sila Sveta presented a unique mix of multimedia technologies, including projection on kinetic surfaces suspended on winches. The creative visual content of the show was seamlessly connected with the technical part reflecting the approach of Lamborghini engineers to the creation of Urus.
The main part of the setup is 56 triangles with LEDs around the perimeter (the total length of the LED strip is almost 900 feet), suspended on 168 kinetic winches. Separately and all together, they served as canvases for the large-scale projection show in combination with the background screens. There were 14 projectors used, including the most modern ones with the brightness level of 30,000 lumens and a 4K resolution. This made for an awe-inspiring example of how 3D projection mapping and multimedia technologies can come together to express artistic energy.
During the show, each of the elements from the array of LED triangles independently moved in space forming polygonal three-dimensional figures for projection mapping. The technological concept of the show was fully developed and implemented by Sila Sveta experts. The show was controlled with the Disguise 4x4pro and TouchDesigner multimedia servers running specially developed software.
Projecting on arrays of constantly changing voluminous shapes sounds like a true technological challenge. However Sila Sveta came up with a clever software solution that makes the preparation process much easier. The main technological innovation of the show was a specially developed software algorithm that calculated the movement of all 56 light triangles: for this purpose, we used data obtained directly from the design software, thus no programming of each triangle individually was required. Having successfully passed the field test, the software tool can now be used to create various polygonal shapes for future multimedia spectacles, using any available number of triangles.
