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 approach of getting this into ParaView, I was wondering if it's possible to create a filter that takes a point value (or two), runs it through some specified (Python) code, and uses the returned RGB tuple for rendering the plot.
Any hints? Cheers, Nico [1] https://github.com/BIDS/colormap/issues/6#issuecomment-220839685
