Research Abstract

First, ferrofluid motion under a strong magnetic field was recorded in high-resolution images. Then, these images were observed to understand the process of generating a ferrofluid spike. Two-dimensional (2D) CG algorithms were developed to generate a 2D ferrofluid spike. We also applied a 2D fluid CG technique (general Navier-Stokes equation for non-elastic fluid)to our new system, in which a ball device is used as an input device that affects the fluid graphics projected on the floor. This interactive system generates real-time fluid graphics (such as a marbling pattern) from the time and location where the ball strikes; one can play with the ball to see fluid patterns and motion, by controlling the ball's rotation, speed, and bounce. The objective of my study is to apply the CG algorithm of generating a ferrofluid spike to media art works.
