class IntConicQuad from IntAna
|
|
|
|
---Purpose: This class provides the analytic intersection between
|
|
-- a conic defined as an element of gp (Lin,Circ,Elips,
|
|
-- Parab,Hypr) and a quadric as defined in the class
|
|
-- Quadric from IntAna.
|
|
-- The intersection between a conic and a plane is treated
|
|
-- as a special case.
|
|
--
|
|
-- The result of the intersection are points (Pnt from
|
|
-- gp), associated with the parameter on the conic.
|
|
--
|
|
-- A call to an Intersection L:Lin from gp and
|
|
-- SPH: Sphere from gp can be written either :
|
|
-- IntAna_IntConicQuad Inter(L,IntAna_Quadric(SPH))
|
|
-- or :
|
|
-- IntAna_IntConicQuad Inter(L,SPH) (it is necessary
|
|
-- to include IntAna_Quadric.hxx in this case)
