43//! Root class for 3D curves on which geometric
44//! algorithms work.
45//! An adapted curve is an interface between the
46//! services provided by a curve and those required of
47//! the curve by algorithms which use it.
48//! Two derived concrete classes are provided:
49//! - GeomAdaptor_Curve for a curve from the Geom package
50//! - Adaptor3d_CurveOnSurface for a curve lying on
51//! a surface from the Geom package.

52//!
53//! Polynomial coefficients of BSpline curves used for their evaluation are
54//! cached for better performance. Therefore these evaluations are not
55//! thread-safe and parallel evaluations need to be prevented.
