MRPAS field of view algorithm & live demo

[Domas Lapinskas]

Hey guys,

I ported MRPAS field of view calculation algorithm to javascript for a rougelike I'm working on.

It's used to calculate what a character can see in a 2d, tile based game.

Couldn't find anything  similar in javascript, so I thought it might be useful to someone else. 

Live demo using gamejs:

hi domas,
i like it, certainly a bit more readable then the original. and it's so fast. all the crappy self-made FOVs I did were dead slow :P
