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
