42 | //! This class implements the algorithms used to |
43 | //! create 2d circles tangent to 3 points/lines/circles. |
44 | //! The arguments of all construction methods are : |
45 | //! - The three qualified elements for the |
46 | //! tangency constraints (QualifiedCirc, QualifiedLine, |
47 | //! Points). |
48 | //! - A real Tolerance. |
49 | //! Tolerance is only used in the limit cases. |
50 | //! For example : |
51 | //! We want to create a circle tangent to an UnqualifiedCirc |
52 | //! C1 and an UnqualifiedCirc C2 and an UnqualifiedCirc C3 |
53 | //! with a tolerance Tolerance. |
54 | //! If we do not use Tolerance it is impossible to find |
55 | //! a solution in the following case : C2 is inside C1 |
56 | //! and there is no intersection point between the two |
57 | //! circles, and C3 is completly outside C1. |
58 | //! With Tolerance we will find a solution if the |
59 | //! lowest distance between C1 and C2 is lower than or |
60 | //! equal Tolerance. |
