Projection mapping of a waterfall is simulated onto the Grand Palais in Paris. The simulation of the waterfall was created from calculations based on the movement of water as it fell onto a model of the Grand Palais in a virtual 3-D space.

The water is expressed as a continuum of hundreds of thousands of water particles that flow in accordance with computer calculations of the particle interaction. Lines are then drawn over the particles to express the waterfall. The video artwork consists of a 3-D waterfall created in a 3-D virtual space, in accordance with what teamLab calls ultrasubjective space.
