We present a novel walk-through 3D display based on the patented FogScreen, an "immaterial" indoor 2D projection screen, which enables high-quality projected images in free space. We extend the basic 2D FogScreen setup in three major ways. First, we use head tracking to provide correct perspective rendering for a single user. Second, we add support for multiple types of stereoscopic imagery. Third, we present the front and back views of the graphics content on the two sides of the FogScreen, so that the viewer can cross the screen to see the content from the back. The result is a wall-sized, immaterial display that creates an engaging 3D visual.
