It took me 5 minutes to do a spice simulation sufficient to generate
such a picture.

The components were an ideal ac voltage source,
a diode, an ideal capacitor for smoothing, an ideal resistor for the
load, and an ideal resistor in series with the smoothing capacitor
representing the smoothing cap's ESR.

You achieved full-wave rectification using just the above parts? May we
see this remarkable circuit, please?
