void IntPatch_Intersection::SetTolerances	(	const Standard_Real	TolArc,
		const Standard_Real	TolTang,
		const Standard_Real	UVMaxStep,
		const Standard_Real	Fleche
	)

Set the tolerances used by the algorithms: — Implicit - Parametric — Parametric - Parametric — Implicit - Implicit.

TolArc is used to compute the intersections between the restrictions of a surface and a walking line.

TolTang is used to compute the points on a walking line, and in geometric algorithms.

Fleche is a parameter used in the walking algorithms to provide small curvatures on a line.

UVMaxStep is a parameter used in the walking algorithms to compute the distance between to points in their respective parametrtic spaces.

Standard_Boolean IntPatch_Intersection::TangentFaces ( ) const

Returns True if the two patches are considered as entierly tangent, i-e every restriction arc of one patch is inside the geometric base of the other patch.
