|

//! to find a solution when, mathematically, the problem
|

//! posed does not have a solution, but where there is
|

|
|
//! For example, take:
|
|
//! - two circles C1 and C2, such that C2 is inside C1,
|
|
//! and almost tangential to C1; there is in fact no point
|
|
//! of intersection between C1 and C2; and
|
|
//! - a circle C3 outside C1.
|
|
//! You now want to find a circle which is tangential to C1,
|
|
//! C2 and C3: a pure mathematical resolution will not find
|
|
//! a solution. This is where the tolerance criterion is used:
|
|
//! the algorithm considers that C1 and C2 are tangential if
|
|
//! the shortest distance between these two circles is less
|
|
//! than or equal to Tolerance. Thus, the algorithm finds a solution.
|
|
//! Warning
|
|
//! An iterative algorithm is used if Qualified1, Qualified2 or
|
|
//! Qualified3 is more complex than a line or a circle. In
|
|
//! such cases, the algorithm constructs only one solution.
|
|
//! Exceptions
