% Generate the properties for a polygon given vertices in the form v(3,n). It assumes that the polygon is planar. It computes an average normal at all vertices. -------------------------------------------------------------------------- Form: [area, n, r] = Polygon( v ) -------------------------------------------------------------------------- ------ Inputs ------ v (3,:) Vertices ------- Outputs ------- area (1,1) Area of the polygon n (3,1) Normal r (3,1) Geometric center -------------------------------------------------------------------------- Reference: Hill, F.S., Jr. Computer Graphics. --------------------------------------------------------------------------
