Detailed Description

Geometric intersections between two natural quadrics (Sphere , Cylinder , Cone , Pln from gp). The possible intersections are :

1 point
1 or 2 line(s)
1 Point and 1 Line
1 circle
1 ellipse
1 parabola
1 or 2 hyperbola(s).
Empty : there is no intersection between the two quadrics.
Same : the quadrics are identical
NoGeometricSolution : there may be an intersection, but it is necessary to use an analytic algorithm to determine it. See class IntQuadQuad from IntAna.
