Standard_Boolean	Perform ()
	computation of the minimum distance (value and couple of points). Parameter theDeflection is used to specify a maximum deviation of extreme distances from the minimum one. Returns IsDone status.
Standard_Boolean	IsDone () const
	True if the minimum distance is found.
Standard_Integer	NbSolution () const
	Returns the number of solutions satisfying the minimum distance.
Standard_Real	Value () const
	Returns the value of the minimum distance.
Standard_Boolean	InnerSolution () const
	True if one of the shapes is a solid and the other shape is completely or partially inside the solid.
const gp_Pnt &	PointOnShape1 (const Standard_Integer N) const
	Returns the Point corresponding to the <N>th solution on the first Shape
const gp_Pnt &	PointOnShape2 (const Standard_Integer N) const
	Returns the Point corresponding to the <N>th solution on the second Shape
BRepExtrema_SupportType	SupportTypeShape1 (const Standard_Integer N) const
	gives the type of the support where the Nth solution on the first shape is situated: IsVertex => the Nth solution on the first shape is a Vertex IsOnEdge => the Nth soluion on the first shape is on a Edge IsInFace => the Nth solution on the first shape is inside a face the corresponding support is obtained by the method SupportOnShape1
BRepExtrema_SupportType	SupportTypeShape2 (const Standard_Integer N) const
	gives the type of the support where the Nth solution on the second shape is situated: IsVertex => the Nth solution on the second shape is a Vertex IsOnEdge => the Nth soluion on the secondt shape is on a Edge IsInFace => the Nth solution on the second shape is inside a face the corresponding support is obtained by the method SupportOnShape2
TopoDS_Shape	SupportOnShape1 (const Standard_Integer N) const
	gives the support where the Nth solution on the first shape is situated. This support can be a Vertex, an Edge or a Face.
TopoDS_Shape	SupportOnShape2 (const Standard_Integer N) const
	gives the support where the Nth solution on the second shape is situated. This support can be a Vertex, an Edge or a Face.
void	ParOnEdgeS1 (const Standard_Integer N, Standard_Real &t) const
	gives the corresponding parameter t if the Nth solution is situated on an Egde of the first shape
void	ParOnEdgeS2 (const Standard_Integer N, Standard_Real &t) const
