The Chair of Landscape Architecture – Professor Christophe Girot – asked its students to experiment with physical sand modelling combined with real-time digital analysis to develop speculative and precise landscape structures. The terrain models were formed in an iterative design process exploring various landscape scenarios. The digital analysis, which was displayed on a screen in front of the sand box, revealed functional considerations such as slope and water levels while the tangible sand box could be interpreted cognitively. With this method it was possible to quickly sample and evaluate both performative and poetic properties of several landscape topologies.
