Detailed Description

This class is root class for classes dedicated to calculate 2d and 3d points and tangents of intersection lines of two surfaces of different types for given u, v parameters of intersection point on two surfaces.

The field myUseSolver is used to manage type of calculation: if myUseSolver = true, input parameters u1, v1, u2, v2 are considered as first approximation of exact intersection point, then coordinates u1, v1, u2, v2 are refined with help of the solver used in intersection algorithm and required values are calculated. if myUseSolver = false, u1, v1, u2, v2 are considered as "exact" intersection points on two surfaces and required values are calculated directly using u1, v1, u2, v2
