Defines curves as constraints to be used to deform a surface.
Public Member Functions |
| GeomPlate_CurveConstraint () |
| Initializes an empty curve constraint object.
|
| GeomPlate_CurveConstraint (const Handle< Adaptor3d_HCurveOnSurface > &Boundary, const Standard_Integer Order, const Standard_Integer NPt=10, const Standard_Real TolDist=0.0001, const Standard_Real TolAng=0.01, const Standard_Real TolCurv=0.1) |
| Create a constraint
Order is the order of the constraint. The possible values for order are -1,0,1,2.
Order i means constraints Gi
Npt is the number of points associated with the constraint.
TolDist is the maximum error to satisfy for G0 constraints
TolAng is the maximum error to satisfy for G1 constraints
TolCurv is the maximum error to satisfy for G2 constraints
These errors can be replaced by laws of criterion.
Raises ConstructionError if Order is not -1 , 0, 1, 2

| GeomPlate_CurveConstraint (const Handle< Adaptor3d_HCurve > &Boundary, const Standard_Integer Tang, const Standard_Integer NPt=10, const Standard_Real TolDist=0.0001) |
| Create a constraint
Order is the order of the constraint. The possible values for order are -1,0.
Order i means constraints Gi
Npt is the number of points associated with the constraint.
TolDist is the maximum error to satisfy for G0 constraints
These errors can be replaced by laws of criterion.
Raises ConstructionError if Order is not 0 or -1

void | SetOrder (const Standard_Integer Order) |
| Allows you to set the order of continuity required for
the constraints: G0, G1, and G2, controlled
respectively by G0Criterion G1Criterion and G2Criterion.
|
Standard_Integer | Order () const |
| Returns the order of constraint, one of G0, G1 or G2.
|
Standard_Integer | NbPoints () const |
| Returns the number of points on the curve used as a
constraint. The default setting is 10. This parameter
affects computation time, which increases by the cube of
the number of points.
|
void | SetNbPoints (const Standard_Integer NewNb) |
| Allows you to set the number of points on the curve
constraint. The default setting is 10. This parameter
affects computation time, which increases by the cube of
the number of points.
|
void | SetG0Criterion (const Handle< Law_Function > &G0Crit) |
| Allows you to set the G0 criterion. This is the law
defining the greatest distance allowed between the
constraint and the target surface for each point of the
constraint. If this criterion is not set, TolDist, the
distance tolerance from the constructor, is used.
|
void | SetG1Criterion (const Handle< Law_Function > &G1Crit) |
| Allows you to set the G1 criterion. This is the law
defining the greatest angle allowed between the
constraint and the target surface. If this criterion is not
set, TolAng, the angular tolerance from the constructor, is used.
Raises ConstructionError if the curve is not on a surface
|
void | SetG2Criterion (const Handle< Law_Function > &G2Crit) |
Standard_Real | G0Criterion (const Standard_Real U) const |
| Returns the G0 criterion at the parametric point U on
the curve. This is the greatest distance allowed between
the constraint and the target surface at U.
|
Standard_Real | G1Criterion (const Standard_Real U) const |
| Returns the G1 criterion at the parametric point U on
the curve. This is the greatest angle allowed between
the constraint and the target surface at U.
Raises ConstructionError if the curve is not on a surface
|
Standard_Real | G2Criterion (const Standard_Real U) const |
| Returns the G2 criterion at the parametric point U on
the curve. This is the greatest difference in curvature
allowed between the constraint and the target surface at U.
Raises ConstructionError if the curve is not on a surface

Handle_Adaptor3d_HCurve | Curve3d () const |
void | SetCurve2dOnSurf (const Handle< Geom2d_Curve > &Curve2d) |
| loads a 2d curve associated the surface resulting of the constraints
|
Handle_Geom2d_Curve | Curve2dOnSurf () const |
| Returns a 2d curve associated the surface resulting of the constraints
|
void | SetProjectedCurve (const Handle< Adaptor2d_HCurve2d > &Curve2d, const Standard_Real TolU, const Standard_Real TolV) |
| loads a 2d curve resulting from the normal projection of
the curve on the initial surface
|
Handle_Adaptor2d_HCurve2d | ProjectedCurve () const |
| Returns the projected curve resulting from the normal projection of the
curve on the initial surface
