class AnaIntersection from IntAna2d

|
|
---Purpose: Implementation of the analytical intersection between:
|
|
-- - two Lin2d,
|
|
-- - two Circ2d,
|
|
-- - a Lin2d and a Circ2d,
|
|
-- - an element of gp (Lin2d, Circ2d, Elips2d, Parab2d, Hypr2d)
|
|
-- and another conic.
|
|
-- No tolerance is given for all the intersections: the tolerance
|
|
-- will be the "precision machine".
