computes the box from a surface
Functions to add a surface to a bounding box.
The surface is defined from a Geom surface.
Adds to the bounding box B the surface S <br>
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 );
Adds to the bounding box B the surface S <br>
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.
