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)
