OCC.BndLib module

The BndLib package provides functions to add a geometric primitive to a bounding box.Note: these functions work with gp objects, optionallylimited by parameter values. If the curves and surfacesprovided by the gp package are not explicitlyparameterized, they still have an implicit parameterization,similar to that which they infer for the equivalent Geom or Geom2d objects.Add : Package to compute the bounding boxes for elementaryobjects from gp in 2d and 3d .AddCurve2d : A class to compute the bounding box for a curvein 2d dimensions ;the curve is defined by a toolAddCurve : A class to compute the bounding box for a curvein 3d dimensions ;the curve is defined by a toolAddSurface : A class to compute the bounding box for a surface.The surface is defined by a tool for the geometry and anothertool for the topology (only the edges in 2d dimensions)-Level : Public.All methods of all classes will be public.

  • 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.
