The authors describe an installation that was shown at the exhibition The Best of All Possible Worlds at Technische Sammlungen Dresden in 2016. The installation provided an interactive experience of the evolution of a complex bicontinuous structure of two immiscible fluids. The evolution is driven by the surface tension of the interface of the two fluids, which results in a continuous reduction of the interface area. The process is mathematically described by a partial differential equation, which is numerically solved. In each time step, the structure, visualized by the fluid-fluid interface, is rendered and shown on an elastic display. According to the deformation of the display, the corresponding time frame is projected. By pushing against the elastic display, one therefore can interact with the structure and evolve it in time in a playful and intuitive manner.

双连续结构的交互演化

作者描述了 2016 年在德累斯顿 Technische Sammlungen 展览“所有可能世界中最好的”中展出的装置。该装置提供了两种不混溶流体的复杂双连续结构演化的互动体验。演化是由两种流体界面的表面张力驱动的，这导致界面面积不断减小。该过程由偏微分方程在数学上描述，该方程通过数值求解。在每个时间步长中，由流体-流体界面可视化的结构被渲染并显示在弹性显示器上。根据显示器的变形情况，投影出相应的时间帧。通过推动弹性显示器，
