Omni-Directional stereoscopyWritten by Paul Bourke
Siggraph-Asia user group meeting, Singapore, December 2008.
In the following I discuss and derive the optical requirements for stereoscopic projection into hemispherical domes, this is applicable to both large scale planetariums and smaller personal domes. It is the development of the later smaller domes, referred to as the iDome, that employ a new lower cost projection system [Bourke 2005] that has been the motivation for this work. Primarily the discussion focuses on how to create optimal omni-directional stereoscopic fisheye pairs, that is, stereoscopic projections that are largely view direction independent. These have some interesting differences and challenges to the usual planar perspective pairs encountered in systems comprising of flat display panels.omnistereo.pdf
