53 | //! The Geom2dGcc package describes qualified 2D |
54 | //! curves used in the construction of constrained geometric |
55 | //! objects by an algorithm provided by the Geom2dGcc package. |
56 | //! A qualified 2D curve is a curve with a qualifier which |
57 | //! specifies whether the solution of a construction |
58 | //! algorithm using the qualified curve (as an argument): |
59 | //! - encloses the curve, or |
60 | //! - is enclosed by the curve, or |
61 | //! - is built so that both the curve and this solution are external to one another, or |
62 | //! - is undefined (all solutions apply). |
63 | //! These package methods provide simpler functions to construct a qualified curve. |
64 | //! Note: the interior of a curve is defined as the left-hand |
65 | //! side of the curve in relation to its orientation. |
