It is usually not too difficult to translate existing C code to
Mathematica (as long as it doesn't use pointers). Making it efficient,
functional programming, code is an entirely different matter.
Your question provoked my interest and I've been looking into this
polygon union stuff, but it's pretty complicated stuff. Not something
you'd write in a few lines of Mathematica code alas...
