CPL Invests in New Projectors for Arcadia London
Central Presentations Ltd (CPL) has invested in six brand new Barco UDX-4K laser projectors which were deployed on their first event at Arcadia London staged in London’s Queen Elizabeth Olympic Park. CPL has been involved with Arcadia since 2013 when the incredible 50 tonne Spider –the conceptual brainchild of Pip Rush and Bert Cole. CPL’s team was project managed by George Oakey who was joined by Jack Sykes and Robin Emery. They worked closely with Arcadia’s production manager Dorian CameronMarlow and Tom Wall who co-ordinated all the video mapping. Fitted with TLD 2.8 – 4.5 lenses, each projected image was mapped precisely onto the front and back of the Spider’s legs via Arcadia’s AI media server which stored and replayed all the video content. Most of it was colouring and texturing effects which bring additional definition and depth to the legs so they really pop out, while the rest of the Spider is illuminated by lighting rigged on the body, legs and lighting towers positioned aroundthe performance field. The projectors were located on six custom weatherised scaffolding towers built around the perimeter of the field-of-play / performance space as in previous years, with a throw distance of approximately 40 metres. The UDX4K32 has 4K UHD resolution and a guaranteed 31,000 lumen output with accurate colours at all times thanks to its Constant Light Output (CLO) functionality. “There was a noticeable difference in the quality and feel of the projections on this show,” commented George, who has worked on previous UK Arcadia shows where they used conventional lamped rather than laser projectors. One of the technical challenges of Arcadia London was getting a stable data signal run out to the projectors across 150 – 300 metre fibre cables around the perimeter of the performance space. CPL used six of their Connex 2-way fibre DVI/RJ45 fibre optic converter transmission systems which enabled both the data carrying the content to the machines and the projector control network and signals including on/off, colour settings, contrast, geometry control and other monitoring and feedback to run down the same line. For the first time CPL also had remote control over the projectors using Barco’s Projector Toolset software, developed to help manage the projector parameters quickly and easily from any location, either through the network or an RS232 connection. This was especially helpful during the video content mapping process, allowing George and the team to walk the field with a laptop and adjust the projectors from exactly the right spots to see the full detail and exactly how and what tweaks needed to be applied.
