Edit and compile if you like:\documentclass[border=10pt]{standalone} \usepackage{pgfplots} \pgfplotsset{width=7cm,compat=1.8} \begin{document} \begin{tikzpicture} \begin{axis}[ hide axis, view = {40}{40} ] \addplot3 [ surf, colormap/greenyellow, shader = faceted interp, point meta = x, samples = 40, samples y = 5, z buffer = sort, domain = 0:360, y domain =-0.5:0.5 ] ( {(1+0.5*y*cos(x/2)))*cos(x)}, {(1+0.5*y*cos(x/2)))*sin(x)}, {0.5*y*sin(x/2)} ); \addplot3 [ samples=50, domain=-145:180, % The domain needs to be adjusted manually, % depending on the camera angle, unfortunately samples y=0, thick ] ( {cos(x)}, {sin(x)}, {0} ); \end{axis} \end{tikzpicture} \end{document}
