Visualizing Virtual Reality Imagery through Digital Holography

Abstract

Tilt Brush, the Virtual Reality (VR) painting application developed by Google, is an impressive tool for creating digital 3D imagery, offering great new possibilities for art making and the creative industries. At the moment, Tilt Brush is still far from ubiquitous due to constraints such as the high cost of purchasing a VR system and the physical space required to run it. This means, on the one hand, that only a small number of creatives have the opportunity to work with this application and, on the other hand, that their artworks are inaccessible to most people, unless reduced to a 2D experience. However, if images created in VR were to be turned into holograms, the three-dimensionality of these productions could be preserved and experienced without the use of a VR headset, which would make them accessible to a wider public. This paper describes the process of transferring a project produced in Tilt Brush onto holographic format in order to obtain a double parallax hologram, and the difficulties encountered along the way.
