computes the box from a surface Functions to add a surface to a bounding box. The surface is defined from a Geom surface.
◆ Add() [1/2]
Adds to the bounding box B the surface S B is then enlarged by the tolerance value Tol. Note: depending on the type of curve, one of the following representations of the surface S is used to include it in the bounding box B:
- an exact representation if S is built from a plane, a cylinder, a cone, a sphere or a torus,
- the poles of the surface if S is built from a Bezier surface or a BSpline surface,
- the points of an approximation of the surface S in cases other than offset surfaces;
- in the case of an offset surface, the basis surface is first included according to the previous rules; then the bounding box is enlarged by the offset value. Warning Do not use these functions to add a non-finite surface to the bounding box B. If UMin, UMax, VMin or VMax is an infinite value B will become WholeSpace. S is an adapted surface, that is, an object which is an interface between:
- the services provided by a surface from the package Geom
- and those required of the surface by the computation algorithm. The adapted surface is created in the following way: Handle(Geom_Surface) mysurface = ... ; GeomAdaptor_Surface S(mysurface); The bounding box B is then enlarged by adding this surface: Bnd_Box B; // ... Standard_Real Tol = ... ; AddSurface::Add ( S, Tol, B );
◆ Add() [2/2]
Adds to the bounding box B the surface S the patch of the surface S limited in the u parametric direction by the two parameter values UMin, UMax, and in the v parametric direction by the two parameter values VMin, VMax. Note: depending on the type of curve, one of the following representations of the surface S is used to include it in the bounding box B:
- an exact representation if S is built from a plane, a cylinder, a cone, a sphere or a torus,
- the poles of the surface if S is built from a Bezier surface or a BSpline surface,

◆ AddGenSurf()
Adds to the bounding box B the surface S using numerical minimization algorithms This method is used in AddOptimal for not analytical surfaces and torus. if Tol < Precision::Confusion(), Precision::Confusion is used as computation tolerance.
◆ AddOptimal() [1/2]
Adds the surface S to the bounding box B. This algorithm builds precise bounding box.
