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)

		Standard_Boolean &	theOpposite
	)		const

if HasPreviousCurve(I) returns True, this function returns the Index J of the curve which has a common bound with the curve I. If theOpposite == True , then the first parameter of the curve I, and the first parameter of the curve J give the same point. Else the first parameter of the curve I and the last parameter of the curve J are the same point.
