title: The geometry of specific horopters.
abstract: The analysis by Helmholtz (1910) of the geometry of binocular vision has been modified to allow computerized calculation of specific examples of horopters. These are used to clarify the relationship between the shapes of the horopters and the physiological constraints involved.
