Detailed Description

This class provides the analytic intersection between a cylinder or a cone from gp and another quadric, as defined in the class Quadric from IntAna. This algorithm is used when the geometric intersection (class QuadQuadGeo from IntAna) returns no geometric solution. The result of the intersection may be.

• Curves as defined in the class Curve from IntAna
• Points (Pnt from gp)
