## Main Question or Discussion Point

Normally, complex plot visualization is a 4D problem. Coloring re or im separately isn't very intuitive.

Otoh, using Mathematica's ParametricPlot3d gives all the information and leaves us with the z-axis unused. Example for z→z+k/z:

I'm trying to find a surface which when projected onto the xy-plane gives the iso displacement lines of the complex parametric plot. (Mathematica uses polygons for computation here).

An alternative would be to compute the grid line density for the z-value.

I looked at a density/contour plot, but it appears quite different:

How would you go about this? Is this connected to riemann surfaces? It seems for higher k's the surface would intersect/overlap itself/ project non-injective.
