Should stereo media attempt to recreate the scene like a puppet theater in front of the viewer, or simply give a good impression of depth? How should we arrange the geometry to achieve each of these? This session will cover epipolar geometry (recreating the images caused by physically present objects), which is fundamental to stereo viewing in the natural environment – as well as deviations from this geometry and how each affects the visual system with consequences ranging from none at all, to eyestrain, to distorted perception.

In stereo media, as in the real world, people combine the cues to depth to form a coherent perception of the 3D environment. But in stereoscopic 3D media, depth cues do not typically correspond to what the viewer would experience in a given scene and are also not in agreement with each other. This session covers what vision science has to say about how depth cues are integrated and what happens when they conflict, the role of cue interaction in choosing the configuration of rigs and displays, and how cue interactions create common distortions experienced in stereoscopic 3D media.
