navmesh

I haven't actually started programming for this one yet, but I wanted to see how I would go about doing this anyway.

Say I have a grid of tiles, all of the same size, some traversable and some not. How would I go about creating a navigation mesh of polygons from this grid?

My idea was to take the non-traversable tiles out and extend lines from there edges to make polygons... that's all I have got so far. Any advice?
