宇宙的粒子 Universe of Water Particles

宇宙的粒子 Universe of Water Particles

在电脑空间里把人工卫星[大地2号](ALOS-2)用三维立体技术再现后，利用人工卫星的引力作用使水往下流，而水的流动通过物理引擎计算, 被人工卫星吸引而模拟形成瀑布. 被模拟形成的瀑布, 直接被投影在实物大的人工卫星[大地2号](ALOS-2)上的电子艺术作品。

水, 用无数水粒子的连续体来表现，随后计算其粒子之间的相互作用. 瀑布, 由模拟被人工卫星的引力所吸引的水的运动来构筑. 撞在人工卫星上而弹跳的水珠, 在人工卫星的周围巡回, 然后蒸发消失。

然后在所有的水粒子之中随机挑选出0.1%的水粒子，根据这些水粒子的举动在空间中描绘出线。而这些「线的集合」就形成了本作品中的瀑布。也就是说，在这些无数的线的背后，有着数量超过它们本身1000倍以上的水粒子存在，并且借着整体之间的交互作用来决定线的曲线性质。

这么一来这些在三次元空间里被立体描绘出的瀑布，对空间认识的理论结构化为一个影像作品。

A 3-D model of space satellite (ALOS-2) was created in a virtual 3-D space. In the computer environment the satellite has a mass that creates gravity. The fall of water is calculated using physical laws and a waterfall is simulated that is drawn in by the satellites gravity. The simulated waterfall is then projection mapped onto a life-size model of satellite(ALOS-2). 

The water is expressed as continuum of hundreds of thousand of water particles that flow in accordance with how the computer calculates the interaction of the particles. The water particles that hit the satellite bounce off and circulate around the satellite until they evaporate. 

Once an accurate water flow simulation has been constructed 0.1% of the water particles are selected and lines drawn in relation to them. The waterfall is expressed as the combination of these lines. Behind the lines exist thousands of water particles and the curve of the lines drawn depends on their overall interaction. 

The waterfall video artwork is created in 3-D space and uses what we consider to be the logic structure of spatial recognition of our Japanese Ancestors.
