FOR FOREST – The unending Attraction of Nature by Klaus Littmann was inspired by a drawing by Max Peintner. This unrivalled temporary art intervention of a real forest at the soccer stadium in Klagenfurt gained worldwide attention in fall 2019. It not only created the largest of its kind in public space in Austria, but also a unique scientific laboratory in the context of forestry, high resolution multisensor surveying and digital transformation. One major goal of this research cooperation was to create a “Digital 3D Twin” by combining terrestrial laser scanning and high-resolution aerial image capture with an Unmanned Aerial System and explore innovative virtual visualization techniques. The result of this sensor fusion is an extremely dense digital 3D point cloud with more than 27 billion points. The “Making of” this unique collaboration from the artistic and scientific point of view and its digital representation is for the first time presented in the impressive Deep Space 8K visualization environment at the Ars Electronica Festival 2020.
