A real-time shadow approach for an augmented reality application using shadow volumes
M. Haller, S. Drab - A real-time shadow approach for an augmented reality application using shadow volumes - Proceedings of the ACM symposium on Virtual reality software and technology, Osaka, Japan, 2003, pp. 56-65
Shadows add a level of realism to a rendered image. Moreover, they are used as visual clues to determine spacial relationships and real-time shadows will gain importance in current real-time computer graphics applications for this reason. Twenty-five years ago, Crow published the shadow volume approach for determining shadowed regions of a scene. In this paper we present a modified real-time shadow volume algorithm that can be used in an Augmented/Mixed Reality application. Finally, the proposed concepts provide a novel sense of visual output of an AR application.
