Hi everyone,
I need to plot complex-valued functions over various domains, and instead
of splitting the values into real and imaginary part (or absolute value and
angle), I would like to use a "2D colormap" approach as sometimes suggested
for complex-valued functions (see, e.g., [1]).
As a lowkey
You can achieve this by writing making a filter that creates a 3D vector field
where each vector represents an RGB color. If writing out floating point
values, the color channel values should be between 0 and 1. You can then render
this 3D vector field directly as colors by turning off the “Map
