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)?

You can use nonlinear transformations to achieve this effect.

.) 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}

% 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)

I'm afraid this only answers the bonus question, for flags of Germany, Netherlands, etc. only. How can it deal with, for example, the US flag?

@JouleV I switched gears completely and used nonlinear transformations. That way you can wave any flag you have the TikZ code for.

You can use nonlinear transformations to achieve this effect.

This answer has the codes for many flags, out of which I picked Iceland. (Note that if the flag contains shapes, you need to say transform shape nonlinear=true
.) The shading can be added on top.

With shade
you can get something like this.

foreach X [count=Y] in {gerbla,gerred,geryel}

I'm afraid this only answers the bonus question, for flags of Germany, Netherlands, etc. only. How can it deal with, for example, the US flag?

This answer has the codes for many flags, out of which I picked Iceland. (Note that if the flag contains shapes, you need to say transform shape nonlinear=true
.) 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}
begin{tikzpicture}[tdplot_main_coords]

% 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.

I'm afraid this only answers the bonus question, for flags of Germany, Netherlands, etc. only. How can it deal with, for example, the US flag?
