Digital Projection’s M-Vision Projectors Help Revitalise Roshen Factory

Digital Projection units were used as part of a permanent video-mapping installation from Les Éclaireurs for the prestigious confectioner in Ukraine’s capital city.

A total of 20 Digital Projection M-Vision Laser 21000 units have been used as part of a multimedia facelift for the Roshen confectionary factory in Kiev, Ukraine; one of Eastern Europe’s most recognised institutions.

The installation – which features illuminated fountains and an animated ice rink alongside the video projections – was headed by French light design agency Les Éclaireurs, whose artistic director, Lucas Goy, took care of multimedia and lighting design, as well as show programming and content.

“We designed the lighting, mapping and sound systems together with Peutz and The Space Factory, as well as fountain designer Philippe Carton,” said Lucas. “We also assumed the artistic direction of the mapping (both form and content) and coordinated the audio with musician and composer, Yi-Ping Yang.”

As well as the extensive catalogue of content Les Éclaireurs created, the client wanted another distinct show to be entrusted to Kiev-based company, Front Pictures, to ensure diversity of approach and the inclusion of local creativity.

Combatting Light Pollution
To ensure that the projection mapping aspect of this ambitious installation lived up to the high standards set by the client, the team conducted an exhaustive analysis of the technology available; ultimately deciding that Digital Projection was the right choice across the board.

“The high performance of the laser sources, combined with the compactness of the projectors, and the quality to price ratio made us prefer Digital Projection by far,” said Lucas. “The challenge was integrating the products into a balcony, which was erected to ensure that the nuts and bolts of the project remained discreet.

“We looked first at Digital Projection’s M-Vision Laser 18K units, eventually opting for the M-Vision Laser 21000’s,” said Lucas. “The client and the artists involved were all impressed by the power of the projectors, especially since the site is particularly exposed to light pollution from the nearby road.”

The M-Vision Laser 21000 projectors were the ideal choice thanks to their ColorBoost+ Red Laser technology, where red lasers are combined with the traditional laser phosphor illumination, bring the most realistic and saturated colours to this 1-Chip DLP Projector. Coupled with its intelligent processing brings the colour performance ever closer to that of a 3-Chip DLP projector.

Although the city of Kiev has resolved to address this situation, les éclaireurs and the rest of the team could rest assured that the M-Vision units had the brightness and definition to show their content at its best no matter what happens.

“We also appreciated the reliability of the Digital Projection units,” continued Lucas. “They are combined in an AMX monitoring / management system, which controls the proper functioning of all the equipment and gives us feedback on the whole system with hierarchical sets of alerts: opening of the projector boxes, internal temperature, status of the fibre optic communication, status of the IP and DMX switches, control of the blinds and lighting of the site before the shows, and so on.”

The entire multimedia installation was carried out with “great care and professionalism” by Sound House Pro, based in Dnipro, while the electrical installation was taken care of by EQUIPA.

The 20 x M-Vision Laser 21000 projectors themselves were installed in March 2020, under a balcony specifically designed for this purpose. The units are enclosed in boxes specially developed by Audipak, with the whole bank being concealed by a set of acoustically treated wooden gratings.

“Although the install went well overall, we did experience a few thermal challenges due to the shape of the balcony,” said Lucas. “In order to help the Audipak boxes cool down the devices, Sound House Pro fitted an external remote ventilation system that filters fresh air into the boxes. These air intakes maintain the discrete aesthetic though, as they are concealed in the balcony between the units.”

Collaborative Content 
The original concept for the projection mapping content came from Lucas Goy / les éclaireurs, who wanted to focus on the idea of ice as a medium. Having already collaborated with video artist Guillaume Marmin and musician and composer Yi-Ping Yang in the past, the three of them worked together to create the ‘Icescapes’ portion of the show that can be seen now, projected onto the façade of the factory.

“I also created the content for the fountains and lights, while Front Pictures is currently developing several small shows for the site, including a big bell on the façade and a show called ‘Creativity”,” said Lucas.

The content is created using Autodesk 3ds Max and Adobe After Effects at 12K 60Hz and driven by VIOSO Anystation Media servers installed with AV Stumpfl PIXERA software. VIOSO technology was also used for projection calibration / auto-recalibration, as well as full show control. The fountain light show is then driven by software developed by IMMOLAS for fountain specialist, Imperia Vody.

“As we are talking about a 100m x 16m building, the ‘sweet spot’ for projectors would be around 80m away,” said VIOSO France’s Etienne Servant. “We only had 15-20m of space for the audience, cameras, and projectors, so the challenge was how to blend and warp 20 projectors with short throw lenses. We ended up using five VIOSO calibration cameras, which allowed us to automate the process and offer an awesome result with easy recalibration. Five custom-made Anystation Media Servers were also installed for playback and to ensure that all hardware and software receives the scenarios imagined by Lucas Goy.”

The calibration cameras were linked to the same fibre network that controlled the projectors, lighting, and show control.

“We had to use a lot of fibre optic cabling due to the distance between the control room and the video projectors,” explained Lucas. “The media is output via HDMI from the servers and then encoded by EXTRON modules to the fibre optic cable. In the balcony, we have hidden waterproof ventilated cabinets with other EXTRON modules that decode the signal.”

During the installation, Digital Projection helped Lucas’ team with the choice of optics and advised them on some of the intricacies of the equipment itself. “We received logistical help for on-site tests, and for optical corrections during the construction period,” Lucas added.

As a permanent installation, the projection mapping shows can be seen at the Roshen factory every night, while other winter and summer programmes are currently being designed for use in the future.
