Value()

Standard_Real GeomLib_DenominatorMultiplier::Value	(	const Standard_Real	UParameter,
		const Standard_Real	VParameter
	)		const

Returns the value of a(UParameter,VParameter)=.

H0(UParameter)/Denominator(Umin,Vparameter)

D Denominator(Umin,Vparameter)

• ---------------------------—[H1(u)]/(Denominator(Umin,Vparameter)^2) D U
• H3(UParameter)/Denominator(Umax,Vparameter)

D Denominator(Umax,Vparameter)

• ---------------------------—[H2(u)]/(Denominator(Umax,Vparameter)^2) D U
