I've not enough time now to translate the text (in french) but figure, code and

mathematic should be comprehensive.

So try to see :

http://liris.cnrs.fr/aurelien.barbier/download/distance_ray_convex-polygon.pdf

Be careful, the square of the distance is computed !

For each case, the number of operations is given (? represents a test)
