class Add3dCurve from BndLib
|
|
---Purpose: 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.
|
|
|
|
uses Box from Bnd,
|
|
Curve from Adaptor3d
|
|
|
|
is
|
|
Add(myclass; C : Curve from Adaptor3d;
|
|
Tol : Real from Standard;
|
|
B : in out Box from Bnd);
|
|
---Purpose: 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.
