4D Graphs of Complex Functions
Complex functions w=f(z) or u+iv=f(x+iy) can be rendered by surfaces in 4D space (x,y,u,v). Usually restricted to 3D-extractions like (x,y,u=Re(w)) or (x,y,v=Im(w)), here we render the "full 4D" graph by simply projecting all 4 axes into graph space, whether in 2D (paper, screen) or in "3D" look. Thus we come to see the full-fledged function surface "as is", albeit a projection... but at least not an extraction.
