 The Rock where People Gather is reproduced in a virtual three-dimensional space. Water is simulated to fall onto the rock, and the flow of the water draws the shape of the waterfall. The water is represented by a continuum of numerous water particles and the interaction between the particles is then calculated. Lines are drawn in relation to the behavior of the water particles. The lines are then “flattened” using what TeamLab considers to be ultrasubjective space.
