Member Function Documentation

Add()

void BRepAlgo_NormalProjection::Add

(

const TopoDS_Shape &

ToProj

)

Add an edge or a wire to the list of shape to project.

Ancestor()

const TopoDS_Shape& BRepAlgo_NormalProjection::Ancestor

(

const TopoDS_Edge &

E

)

const

For a resulting edge, returns the corresponding initial edge.

Build()

void BRepAlgo_NormalProjection::Build

(

)

Builds the result as a compound.

BuildWire()

Standard_Boolean BRepAlgo_NormalProjection::BuildWire

(

TopTools_ListOfShape &

Liste

)

const

build the result as a list of wire if possible in – a first returns a wire only if there is only a wire.

Compute3d()

void BRepAlgo_NormalProjection::Compute3d

(

const Standard_Boolean

With3d = Standard_True

)

if With3d = Standard_False the 3dcurve is not computed the initial 3dcurve is kept to build the resulting edges.

Couple()

const TopoDS_Shape& BRepAlgo_NormalProjection::Couple

(

const TopoDS_Edge &

E

)

const

For a projected edge, returns the corresponding initial face.

Generated()

const TopTools_ListOfShape& BRepAlgo_NormalProjection::Generated

(

const TopoDS_Shape &

S

)

Returns the list of shapes generated from the shape <S>.

Init()

void BRepAlgo_NormalProjection::Init

(

const TopoDS_Shape &

S

)

IsDone()

Standard_Boolean BRepAlgo_NormalProjection::IsDone

(

)

const

IsElementary()

Standard_Boolean BRepAlgo_NormalProjection::IsElementary

(

const Adaptor3d_Curve &

C

)

const

Projection()

const TopoDS_Shape& BRepAlgo_NormalProjection::Projection

(

)

const

returns the result

SetDefaultParams()

void BRepAlgo_NormalProjection::SetDefaultParams

(

)

Set the parameters used for computation in their default values.

SetLimit()

void BRepAlgo_NormalProjection::SetLimit

(

const Standard_Boolean

FaceBoundaries = Standard_True

)

Manage limitation of projected edges.

SetMaxDistance()

void BRepAlgo_NormalProjection::SetMaxDistance

(

const Standard_Real

MaxDist

)

Sets the maximum distance between target shape and shape to project. If this condition is not satisfied then corresponding part of solution is discarded. if MaxDist < 0 then this method does not affect the algorithm.

SetParams()

void BRepAlgo_NormalProjection::SetParams	(	const Standard_Real	Tol3D,
		const Standard_Real	Tol2D,
		const GeomAbs_Shape	InternalContinuity,
		const Standard_Integer	MaxDegree,
		const Standard_Integer	MaxSeg
	)

Set the parameters used for computation Tol3d is the required tolerance between the 3d projected curve and its 2d representation InternalContinuity is the order of constraints used for approximation. MaxDeg and MaxSeg are the maximum degree and the maximum number of segment for BSpline resulting of an approximation.
