static Standard_EXPORT void | Add (const Adaptor2d_Curve2d &C, const Standard_Real Tol, Bnd_Box2d &B) |
Adds to the bounding box B the curve C B is then enlarged by the tolerance value Tol. Note: depending on the type of curve, one of the following representations of the curve C is used to include it in the bounding box B: - an exact representation if C is built from a line, a circle or a conic curve, - the poles of the curve if C is built from a Bezier curve or a BSpline curve, - if not, the points of an approximation of the curve C. Warning C is an adapted curve, that is, an object which is an interface between: - the services provided by a 2D curve from the package Geom2d - and those required of the curve by the computation algorithm. The adapted curve is created in the following way: Handle(Geom2d_Curve) mycurve = ... ; Geom2dAdaptor_Curve C(mycurve); The bounding box B is then enlarged by adding it: Bnd_Box2d B; // ... Standard_Real Tol = ... ; Add2dCurve::Add ( C, Tol, B ); Exceptions Standard_Failure if the curve is built from: - a Geom_Line, or - a Geom_Parabola, or - a Geom_Hyperbola, and P1 and P2 are either two negative infinite real numbers, or two positive infinite real numbers. . | |

Adds to the bounding box Bthe arc of the curve C limited by the two parameter values P1 and P2. B is then enlarged by the tolerance value Tol. Note: depending on the type of curve, one of the following representations of the curve C is used to include it in the bounding box B: - an exact representation if C is built from a line, a circle or a conic curve, - the poles of the curve if C is built from a Bezier curve or a BSpline curve, - if not, the points of an approximation of the curve C.
