Computes the bounding box for a curve in 3d. Functions to add a 3D curve to a bounding box. The 3D curve is defined from a Geom curve.
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 3D curve from the package Geom
 and those required of the curve by the computation algorithm. The adapted curve is created in the following way: Handle(Geom_Curve) mycurve = ... ; GeomAdaptor_Curve C(mycurve); The bounding box B is then enlarged by adding it: Bnd_Box B; // ... Standard_Real Tol = ... ; Add3dCurve::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.
