Light, giant 3D faces and Intel RealSense dazzle SIGNAL 2015


The Prague festival of light, known as SIGNAL, has become one of the biggest cultural events in Europe. The first festival in 2013 attracted over 250,000 visitors to the Czech capital, despite being held in the middle of a chilly autumn. The second SIGNAL managed to double this impressive number and, in 2015, the festival’s popularity grew further.

In 2014, The Guardian newspaper included SIGNAL in it’s 2014 top ten festivals of light in Europe and the festival is a proud member of the International Lightfestival Organisation. What is a festival of light? Take a look at the highlights of SIGNAL 2014 in the video below.

SIGNAL 2015: A new milestone

Buoyed by the success of previous events, the SIGNAL 2015 festival took place from October 15-18 and artists from all over the world transformed Prague into a magical city of light.

Over four evenings, both well-known tourist attractions as well as more common buildings hosted an array of dazzling projected displays that lit up the Czech capital with pulsing patterns and shifting fractals.

The most impressive displays used video mapping technology to match the light shows perfectly to the contours of each building. The National Gallery, for example, rippled with a blaze of colours, vibrating, wobbling, exploding and collapsing. At times, it almost seemed like the facade of the grand old building was moving.

FACES and Intel RealSense

“Intel RealSense played the main role [in the installation],” explained Intel’s Pavel Svoboda. “Equipped with an infrared sensor, it can – among other things – create a detailed 3D model of a human face and it has no problems doing so at night. [We used it] to make 3D facial models of SIGNAL visitors.”Intel - Signal - 16.10. - 101


These eerily accurate 3D models were then projected directly onto the wall of the Šítkovská Tower on the bank of the Vltava. As well as seeing huge representations of themselves sculpted in light, “spectators could even play with individual bricks and could create an illusion of destruction or peel away the exterior of the building,” said Jan Hrdlička from 3dsense. “It was up to them what spectacle they created for themselves.”
