hi
i have two parallel rectangles (so no rotation) and i want to find all shapes formed by intersection.

this is an example:


1----------2
| |
| 5----9----6
| | | |
3----10----4 |
| |
| |
7---------8


first rectangle: 1,2,3,4
second: 5,6,7,8
intersection points: 9,10 (getted by brute force intersecting all segment of first rect with each other of second one.. there is a better way?)

desired output:
1,2,9,5,10,3
5,9,10,4
9,6,8,7,10,4

i hope you understand, sorry for my bad english
