Drawing possible in LaTeX?

[ShayanJ]

Main Question or Discussion Point

Since LaTeX is very powerful, I'm curious whether its possible to do things like the below samples in it. Is it?

Thanks

LaTeX has some basic drawing instrucion set, see for instance http://en.wikibooks.org/wiki/LaTeX/Picture , but I wouldn't recommended it. One has to keep track of all coordinates (points, line, arrows).
Usually I use some vector graphic software which allows LaTeX expressions in its text box because you have a better and much easier control of the picture, I recommend Xfig or Inkscape. I don't know whether CorelDraw has some LaTeX plugin.

The Tikz package could do this.
