Summary

This chapter describes and characterizes the viewing geometry and then presents compatible shooting geometries. It then studies the potential distortions in perceived scenes that a combination of these shooting and viewing geometries may cause. The relations between these distortions and the parameters of the geometries used allows one to propose a specification methodology for the shooting geometry, which can ensure that scenes are perceived with a set of arbitrarily selected possible distortion on the 3DTV device used. Lastly, the chapter provides practical details on how to use this methodology in order to place and configure virtual cameras when calculating synthetic content for 3DTV, and in particular explains the camera arrangement in OpenGL applications. Principally aimed at autostereoscopy, the chapter can be applied to a number of areas in 3D visualization in line with, for example, biomedical imaging, audiovisual production and multimedia production.
