Protec was appointed by Dynamic Motion to provide the projection on the 54m x 21m backdrop screen as well as the central 20m x 20m stage area and a 6m diameter inflatable sphere that was revealed and raised during the show as part of the spectacle while being projected on.
We used BlackTrax integrated with a d3 server, both of which helped track the moving video surface (sphere) while projecting onto it, with the 3D mapping visualised and handled in real-time. This was the first time this 6D tracking system was used to motion track a moving sphere.
10 Christie Roadster 20k projectors where used for the main screen blend, 8 Barco 30k projectors for the central stage area all of which were controlled from the FOH with all signals run over fibre and a further 6 Barco 30k projectors used for the 6m diameter inflatable moving sphere. With d3 4×4 pro media servers, we were able to render and map seamless edge-blended images onto the circular surface area.
Projection mapping on a moving sphere on this scale was a first. In the words of Gilray Densham, President & CEO CAST Group of Companies Inc, the developer of the software, “No one has ever (that I know of), delivered dynamic content onto a moving sphere of this size in a real show environment. You guys did the pioneering to make it all happen.”
