Interactive Ray Tracing for Virtual TV Studio Applications Pomi Andreas Slusallek Philipp In the last years, the well known ray tracing algorithm gained new popularity with the introduction of interactive ray tracing methods. The high modularity and the ability to produce highly realistic images make ray tracing an attractive alternative to raster graphics hardware. Interactive ray tracing also proved its potential in the field of Mixed Reality rendering and provides novel methods for seamless integration of real and virtual content. Actor insertion methods, a subdomain of Mixed Reality and closely related to virtual television studio techniques, can use ray tracing for achieving high output quality in conjunction with appropriate visual cues like shadows and reflections at interactive frame rates. In this paper, we show how interactive ray tracing techniques can provide new ways of implementing virtual studio applications. 3D Compositing Actor Insertion Image-Based Visual Hull In-Shader Rendering Interactive Ray Tracing Mixed Reality OpenRT Rendering Streaming Video Textures Video Billboards Virtual TV Studio 004 periodical academic journal JVRB - Journal of Virtual Reality and Broadcasting 2(2005) 1 2005 1860-2037 urn:nbn:de:0009-6-2480 10.20385/1860-2037/3.2006.1 http://nbn-resolving.de/urn:nbn:de:0009-6-2480 pomi2005
