3D fog display using parallel linear motion platforms

Abstract

Fog screens have been widely used in theme parks and exhibition halls for entertainment and advertising purposes as the semi-transparent images suspending in the mid-air can create impressive pseudo 3D effect. However, conventional fog screens are flat and the projected images are not true 3D in nature. This paper suggests a new 3D fog display that exploits spatial projection mapping technique on a non-planar, reconfigurable fog screen to display volumetric data in real 3D space. The fog screen is composed of columns of upward-flowing laminar fog that are traveling on a set of linear motion platforms. The light beams from the projector are scattered at different depth positions on the fog sc..
