„Tree“ during Ars Electronica, documentation & movie
A forest, half virtual, half real, on Marienstraße, Second City, Ars Electronica 2007. As in most computer games and 3D worlds, objects from the real world are “copied” or simulated in simplified form and in accordance with programming constraints. Textures are applied to 3D structures and, depending on lighting conditions, the images making up the virtual scenery are computed in real time during the game. Most trees are constructed out of two interlocking surfaces, each of which is covered with the same tree-view texture. The transparency of the gaps between the leaves and branches is provided by a so-called alpha channel in the graphics file. From a certain distance and the corresponding perspective, this abstracted form of a tree in virtual space doesn’t stand out as a simplification.
