IntAna_IntConicQuad Class Reference

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)

#include <IntAna_IntConicQuad.hxx>
