%RAYS2D Description of functions operating on planar rays
% A ray is defined by a point (its origin), and a vector (its
% direction). The different parameters are bundled into a row vector:
% RAY = [x0 y0 dx dy];
% The ray contains all the points (x,y) such that:
% x = x0 + t*dx
% y = y0 + t*dy;
% for all t>0
% Contrary to a (straight) line, the points located before the origin do
% not belong to the ray.
% However, as rays and lines have the same representation, some functions
% working on lines are also working on rays (like 'transformLine').
