3D Glossary

A little introduction to the basic terms of stereoscopic 3D recording.

Glossary
accommodation focussing of an observed point
angulation / convergence resulting angle spanned between the optical axes of the two cameras
autostereoscopy

seeing a picture three dimensional without additional utilities (glasses)

binocular with both eyes
convergence to pivot both optical axes to an observed object
depth cues information about the depth of a scene; there are monocular depth cues like perspective and binocular depth cues like stereopsis
deviation

parallactic displacement of corresponding points on two 3D-exposures (left and right image)

disparity

distance of two corresponding points on the retina

far point the farthest point from the nodal point of the camera
Fovea Centralis area of the sharpest vision on the retina
Horopter set of points for which the light falls on corresponding areas in the two retinas
interaxial (distance) / stereo base distance of the center-points of the two camera lenses
interocular distance distance of the center-points of the eyes
monocular with one eye
motion parallax

change of angular position of two stationary points relative to each other as seen by an observer, caused by the motion of an observer

near point the nearest point from the nodal point of the camera
nodal point

point about which a lens is rotated where close and distant subjects focused on the film plane maintain their relative positions to one another

Panum's fusional area

region of binocular single vision

parallax change of angular position of two stationary points relative to each other as seen by an observer. If there is no parallax between two objects then they occupy the same position.
pseudoscopy inversion of the spatial impression
plane of screen image plane mapped directly on the surface of the screen
screen parallax distance of two corresponding points on the screen surface
stereopsis

ability to make fine depth discriminations from parallax provided by the two eye's different positions on the head
