2] - [pi]A, where [alpha] denotes the angle between two tangents from an exterior point (x,y) to the curve of the length L that forms the boundary of a convex region of the area A, and the integral is taken over the whole plane outside the boundary.
A convex region covers a family of arcs if it contains a congruent copy of every arc in the family.
Consequently, the simplified line cannot stray from the convex region determined by vertices of the original line.
For point-line conflicts we must examine points that lie in certain restricted convex regions; for line-line conflicts we need only examine segment end-points that lie in certain restricted convex regions.
This corollary permits a search strategy that (1) conveniently limits the search space to nested sets of convex regions, and (2) examines only line end-points, not the lines themselves.
