question: public static double enlargementScaled ( SpatialComparable exist , SpatialComparable addit , double scale ) { final int dim = assertSameDimensionality ( exist , addit ) ; double v1 = 1. ; double v2 = 1. ; for ( int i = 0 ; i < dim ; i ++ ) { final double emin = exist . getMin ( i ) ; final double emax = exist . getMax ( i ) ; final double amin = addit . getMin ( i ) ; final double amax = addit . getMax ( i ) ; final double min = Math . min ( emin , amin ) ; final double max = Math . max ( emax , amax ) ; v1 *= ( max - min ) * scale ; v2 *= ( emax - emin ) * scale ; } return v2 - v1 ; }
target:  Compute the enlargement obtained by adding an object to an existing object.
