Moment of Inertia for Simple Polygon

[QUOTE="Jack2927, post: 5515984, member: 598910"] I am trying to determine if a function I have is working correctly. The function computes the moment of inertia for a polygon. To test the function I created a polygon that has 4 points and represents a square of 4 units by 4 units. The answer I am getting is 32. I believe the answer should be 42.6 based on J0= Ixx +Iyy, where Ixx = (bh^3)/12 and Iyy = (hb^3)/12. The function I have is implementing the following. [ATTACH=full]102990[/ATTACH] Which is correct 32 or 42.6? [/QUOTE]
