Let's take the flag of Germany as an example, because the flag is way quite simple and its waving state can be easily drawn "manually". But I am asking about general flag (the flag of any country/group, even the flag of my team).

Question
How to draw a waving flag? In other word, say I already have a rectangle-shape flag (1), with many patterns and items on it (even with some includegraphics
), how can I "wave" (1) to get (2), where
- The ratio length/width is still correct.
- The images, patterns, etc. on the flag are waved too, and these items still fit correctly with the overall flag.
Bonus question
If I already have (1) or (2), how can I get shadow effects and light effects like (3)?

In order to draw a 3d flag, you may use tikz-3dplot
.
With shade
you can get something like this.
documentclass[tikz]{standalone}
usepackage{tikz-3dplot}
definecolor{gerbla}{RGB}{0,0,0}
definecolor{gerred}{RGB}{255,0,0}
definecolor{geryel}{RGB}{255,204,0}

% draw[-stealth] (0,0,0) -- (0,2,0) node[pos=1.1]{$y$};
foreach X [count=Y] in {gerbla,gerred,geryel}
{shade[left color=X,right color=X!70!black,middle color=X!70!white]
plot[variable=x,domain=0:2] (x,{0.2*sin(x*90)},4-Y)
--
plot[variable=x,domain=2:0] (x,{0.2*sin(x*90)},3-Y);
shade[left color=X!70!black,right color=X,middle color=X!70!white]
plot[variable=x,domain=2:4] (x,{0.2*sin(x*90)},4-Y)

end{tikzpicture}

.) The shading can be added on top.

In order to draw a 3d flag, you may use tikz-3dplot
.
With shade
you can get something like this.
documentclass[tikz]{standalone}
usepackage{tikz-3dplot}
definecolor{gerbla}{RGB}{0,0,0}
definecolor{gerred}{RGB}{255,0,0}
definecolor{geryel}{RGB}{255,204,0}
begin{document}
tdplotsetmaincoords{70}{20}

% draw[-stealth] (0,0,0) -- (0,2,0) node[pos=1.1]{$y$};
foreach X [count=Y] in {gerbla,gerred,geryel}
{shade[left color=X,right color=X!70!black,middle color=X!70!white]
plot[variable=x,domain=0:2] (x,{0.2*sin(x*90)},4-Y)
--
plot[variable=x,domain=2:0] (x,{0.2*sin(x*90)},3-Y);
shade[left color=X!70!black,right color=X,middle color=X!70!white]
plot[variable=x,domain=2:4] (x,{0.2*sin(x*90)},4-Y)
--
plot[variable=x,domain=4:2] (x,{0.2*sin(x*90)},3-Y);}
end{tikzpicture}
end{document}
You can use nonlinear transformations to achieve this effect.
