Serie XXVIII, Nr 6

Model for the theory of the space curve of order three. Horopter.


Mathematical description
The horopter is a space curve of order three with equations:

                 y = a
                 z = xy.
In optics, it can be interpreted as the set of points for which the light falls on corresponding areas in the two retinas. It is a cubic ellipse on a cylinder with the same asymptote.
