Title:


    Pixie Dust: Graphics Generated by Levitated and Animated Objects in Computational Acoustic-Potential Field

Presenter(s):


Entry Number: 21


Description:


    In this study, we demonstrate real-world-oriented computer graphics by using and expanding 3D acoustic manipulation [Ochiai et al. 2014]. An acoustic potential field (APF) is generated and controlled in order to levitate and manipulate small objects (Fig. 2 (a)). Compared to magnetic levitation, air jets, and other noncontact levitation technologies, our technology has the following advantages: a wide variety of materials are available; it provides a satisfactory refresh rate; and it has a sufficient spatial resolution. It would contributes to the computer graphics community by making the levitated objects usable in graphic metaphors such as the pixels of raster graphics, moving points of vector graphics, and animation (Fig. 1). We believe that it will open a new field of computer graphics if fabricated models can be actuated by APF.
