%LINES2D Description of functions operating on planar lines
% The term 'line' refers to a planar straight line, which is an unbounded
% curve. Line segments defined between 2 points, which are bounded, are
% called 'edge', and are presented in file 'edges2d'.
% A straight line is defined by a point (its origin), and a vector (its
% direction). The different parameters are bundled into a row vector:
% LINE = [x0 y0 dx dy];
% A line contains all points (x,y) such that:
% x = x0 + t*dx
% y = y0 + t*dy;
% for all t between -infinity and +infinity.
