Ideation 360 Dome Projections


On 20 February at White Night Melbourne 2016, Projection Teknik partnered with TDC to achieve a projection mapping first inside La Trobe Reading Room of The State Library of Victoria.
Melbourne is one of seven UNESCO Cities of Literature, which inspired a group of Australian Artists – Nick Azidis, Lisa Greenaway, Adem Jaffers and Bentley Dean – to create Ideation, as a spectacular audio-visual celebration of the power of libraries to teach, inspire and develop knowledge.

The Library’s majestic La Trobe Reading Room is an octagonal 1,000 meter-wide learning space under a 35-meter high-dome. When it was opened in 1913 it was the largest of its kind in the world.

Ideation at White Night Melbourne 2016 paid tribute to this important room by giving it a virtual makeover in the form of illuminated 360-degree artwork. Steve Cain, head technician at TDC, said: “It was a very challenging and complex room to line up each video projector and image.”

The projection area was 120 metres wide by 30 meters high with a full 360-degree blend. High-resolution content was rendered at 8K wide and 2.5K high creating a single image at an amazing 20,000 pixels.

“The size of the image allowed us to do true pixel lock on all server outputs through to projection, making for the sharpest and best possible image,” added Cain. “To achieve this, I made good use of the pre-visualisation tool and footprint features of our d3 4x4pro servers to come up with the best design concept as well as to use every pixel and projector brightness as efficiently as possible.“

“An additional challenge to overcome was achieving pixel perfect blending and focus over building surface curves, balconies that protrude several meters forward and alcoves recessing back several meters, side-by-side. Although this was a challenge, it’s one that we knew how to overcome after many years of mastering different building architectures with projection mapping.”

“To create the video projections this year we used our d3 4x4pro media servers running new VFC output cards as well as play out of fully immersive surround sound, integrated with high-resolution Barco HDF-W26 large-format projectors. It was a great project to do, very cool, and I loved it,” enthused Cain.
