1 libfov is a C library for calculating fields of view and lighting on low
2 resolution rasters, suitable for roguelike games. In that screenshot below,
3 imagine that green dot is your character in a computer game, and as you
4 walk around (move between tiles on the grid), you want to know which tiles
5 you can see and which tiles you cannot. libfov calculates exactly that.
