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: More...

Detailed Description

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.
