WebIn computer vision, the horopter is defined as the curve of points in 3D space having identical coordinates projections with respect to two cameras with the same intrinsic parameters. It is given generally by a twisted cubic, i.e., a curve of the form x = x (θ), y = y (θ), z = z (θ) where x (θ), y (θ), z (θ) are three independent third ... http://www.visionmagazineonline.co.za/wp-content/uploads/2024/archives/The%20Horopter%20and%20its%20clinical%20applications%20online.pdf pitot avion

The horopter was originally defined in geometric terms as the locus of points in space that make the same angle at each eye with the fixation point, although more recently in studies of binocular vision it is taken to be the locus of points in space that have the same disparity as fixation.
