class GccAna_Lin2dBisec

Describes functions for building bisecting lines between two 2D lines.
A bisecting line between two lines is such that each of its
points is at the same distance from the two lines.
If the two lines are secant, there are two orthogonal
bisecting lines which share the angles made by the two
straight lines in two equal parts. If D1 and D2 are the
unit vectors of the two straight lines, those of the two
bisecting lines are collinear with the following vectors:

D1 + D2 for the "internal" bisecting line,
D1 - D2 for the "external" bisecting line.
If the two lines are parallel, the (unique) bisecting line is
the straight line equidistant from the two straight lines. If
the two straight lines are coincident, the algorithm
returns the first straight line as the solution.
A Lin2dTanObl object provides a framework for:
defining the construction of the bisecting lines,
implementing the construction algorithm, and
consulting the result.
