Exponential Tetraview
The tetraview for the exponential function is the most interesting of the
three that appeared in Surfaces Beyond
the Third Dimension. The inverse relation is the complex logarithm,
and the connection between the two is not easy to see. The rotations along
the edges of the tetrahedron can be very helpful in understanding this
surface. The central image incorporates properties from all four of the
other views, giving some sense of how these really are four different views
of the same surface.
The tetraview as a means of understanding complex function graphs is the
subject of an unfinished multi-media article originally intended for
Communications in Visual Mathematics.
