Method: Geometry::Polyline#bisectors

Defined in:
lib/geometry/polyline.rb

#bisectors ⇒ Array<Vector>

Note:

If the Geometry::Polyline isn’t closed (the normal case), then the first and last vertices will be given bisectors that are perpendicular to themselves.

Generate the angle bisector unit vectors for each vertex

Returns:

  • (Array<Vector>) —

    the unit Vectors representing the angle bisector of each vertex
