[Does it exist ? - correction]

Sorry, the ASCII-based illustration I just posted doesn't show anything. I put a bitmapped picture on http://student.ulb.ac.be/~cpaterno/

Thanks.

[Does it exists ?]

Hi. I'm looking for a function (or script) which returns the convex union of two or more distinct 2D polygons.

Example:

****

**** * * ****

* * * * * *

**** * * ****

****

would give:

****

*** ***

**** ****

* *

**** ****

*** ***

****

Have you ever heard of something like that ?

thanks in advance.
