Definition at line 177 of file vsol_spatial_object_2d.h.

vsol_point_2d_sptr vsol_poly_set_2d::centroid ( void ) const [virtual]

Return the centroid of `this'.

The centroid is computed by using Green's theorem to compute the area-weighted 1st moments of the poly_set. Green's theorem relates the surface integral to the line integral around the boundary as: Int(surface) x dxdy = 0.5 * Int(boundary) x*x dy Int(surface) y dxdy = 0.5 * Int(boundary) y*y dx The centroid is given by xc = Int(surface) x dxdy / Int(surface) dxdy = Int(surface) x dxdy/area yc = Int(surface) y dxdy / Int(surface) dxdy = Int(surface) y dxdy/area

For a poly_set: with vertices x[i], y[i] 0.5 * Int(boundary) x*x dy = 1/6 * Sum(i)( x[i+1] + x[i] ) * ( x[i] * y[i+1] - x[i+1] * y[i] )

0.5 * Int(boundary) y*y dx = 1/6 * Sum(i)( y[i+1] + y[i] ) * ( x[i] * y[i+1] - x[i+1] * y[i] )

In the case of degenerate poly_sets, where area == 0, return the average of the vertex locations.
