- I don't know if this is the right place to ask, but I'll give it a try.
- I am currently trying to find constraints for planar (2D) polygons, and in
- particular, I have troubles finding a constraint (=a formula) to calculate
- the area of a polygon.
-
- I know that it is possible to subdivide a polygon into triangles, but I haven't
- found a general formula to find out which diagonals to use for this. With
- convex polygons, things are easy, but I got stuck as far as concave polygons
- are concerned.
-
- Please e-mail me, since I am not reading this list. You can reach me at the
- address listed below.
-
- Thank you for your help,
- Matt Will <willm@igd.fhg.de>
