Intersection between two 3D flat polygon

Hello, I Just trying to compute the result polygon on the intersection of two 3D flat convex polygons defined by their vertices.

They are in the same plane, but this one is in 3D coordinates, and i need to compute the resulting 3d points the define the intersection between the two.

lets say polygon 1 is defines by n vertices(x,y,z) and polygon 2 also, result the points that define the new intersected polygon.

Thanks

You can use this

http://www.mathworks.com/matlabcentral/fileexchange/30892-representing-polyhedral-convex-hulls-by-vertices-or-inequalities

If V1 and V2 are the two sets of vertices

 [A1,b1,Aeq1,beq1]=vert2lcon(V1);

 [A2,b2]=vert2lcon(V2);

 V_intersection=lcon2vert([A1;A2],[b1;b2],Aeq1,beq1),

The same FEX package now contains a function to do this more simply:

I=intersectionHull('vert',V1,'vert',V2);
