View Full Version : Area of the common surface of two polygons

08-05-2009, 01:51 PM
I have two concave polygons in 2D space. These polygons share some space. I want to find the area of their common space.


I want to find the area of the grayed space. Does anyone have an idea, a book recommendation or something?

Thanks in advance!

Hi Theo-morfe!

You can search online for "polygon boolean operations" - effectively, you want the area of the union of the two polygons.

I found quite a few links with math and code.

I hope this helps.
