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.

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.

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.

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.

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

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?

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