Member Function Documentation

void BRepFill_Sweep::Build	(	TopTools_MapOfShape &	ReversedEdges,
		BRepFill_DataMapOfShapeHArray2OfShape &	Tapes,
		BRepFill_DataMapOfShapeHArray2OfShape &	Rails,
		const BRepFill_TransitionStyle	Transition = BRepFill_Modified,

		const GeomFill_ApproxStyle	Approx = GeomFill_Location,
		const Standard_Integer	Degmax = 11,
		const Standard_Integer	Segmax = 30
	)

Build the Sweeep Surface Transition define Transition strategy Approx define Approximation Strategy.

• GeomFill_Section : The composed Function Location X Section is directly approximed.
• GeomFill_Location : The location law is approximed, and the SweepSurface is bulid algebric composition of approximed location law and section law This option is Ok, if Section.Surface() methode is effective. Continuity : The continuity in v waiting on the surface Degmax : The maximum degree in v requiered on the surface Segmax : The maximum number of span in v requiered on the surface.

Standard_Real BRepFill_Sweep::ErrorOnSurface

(

const

Say if the Shape is Build.

Handle< TopTools_HArray2OfShape > BRepFill_Sweep::Sections

)

const

void BRepFill_Sweep::SetAngularControl	(	const Standard_Real	AngleMin = 0.01,
		const Standard_Real	AngleMax = 6.0
	)

Tolerance To controle Corner management.

If the discontinuity is lesser than <AngleMin> in radian The Transition Performed will be alway "Modified"

void BRepFill_Sweep::SetBounds	(	const TopoDS_Wire &	FirstShape,
		const TopoDS_Wire &	LastShape
	)

void BRepFill_Sweep::SetForceApproxC1

(

const Standard_Boolean

ForceApproxC1

)

Set the flag that indicates attempt to approximate a C1-continuous surface if a swept surface proved to be C0.

void BRepFill_Sweep::SetTolerance	(	const Standard_Real	Tol3d,
		const Standard_Real	BoundTol = 1.0,
		const Standard_Real	Tol2d = 1.0e-5,
		const Standard_Real	TolAngular = 1.0e-2
	)

Set Approximation Tolerance Tol3d : Tolerance to surface approximation Tol2d : Tolerance used to perform curve approximation Normaly the 2d curve are approximated with a tolerance given by the resolution on support surfaces, but if this tolerance is too large Tol2d is used. TolAngular : Tolerance (in radian) to control the angle beetween tangents on the section law and tangent of iso-v on approximed surface.

TopoDS_Shape BRepFill_Sweep::Shape

(

)

const

returns the Sweeping Shape

const

TopoDS_Shape BRepFill_Sweep::Tape

(

const Standard_Integer

Index

)

const

returns the Tape corresponding to Index-th edge of section
