I want to draw the following picture using tikz, but i don't know how to color it as 3d object and how to place upper arrow overlay other arrow?
The following, is my try:
\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}[scale=.3,xscale=.8]
\draw (-1,8) arc (90:-82.8:8 and 3);
\draw (-1,8)-- (-1,7);
\draw (7,4)-- (7,5);
\draw (-1,7) arc (90:10:8 and 3);
\draw (7,4) arc (0:-82.8:8 and 3);
\draw (0,1.02) --(0,.5)--(-1.5,1.54) node[left]{cc}--(0,2.5) --(0,2);
%----------------------------------
\draw (-1,1) arc (90:-82.8:8 and 3);
\draw (-1,0)-- (-1,1);
\draw (7,-3)-- (7,-2);
\draw (-1,0) arc (90:10:8 and 3);
\draw (7,-3) arc (0:-82.8:8 and 3);
\draw (0,-5.98) --(0,-6.5)--(-1.5,-5.48) node[left]{cc}--(0,-4.5) --(0,-5);
%----------------------------------
\end{tikzpicture}
\end{document}
