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 2D matrix of squares, all of the same size, some traversable and some not. How would I go about creating a navigation mesh of polygons from this grid. Is there any reading I can look at until I get a chance to get to my computer or should I just give it a go.

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

Any advice?

I'm currently trying to convert from grids to navigation meshes for pathfinding, since grids are either too coarse for accurate navigation, or too fine to be useful for object tracking.

How can I generate a 2d navigation mesh in a dynamic environment at runtime?

So I've grasped how to use A* for path-finding, and I am able to use it on a grid. However, my game world is huge and I have many enemies moving toward the player, which is a moving target, so a grid system is too slow for path-finding. I need to simplify my node graph by using a navigational mesh… >>> More

I'm currently making a prototype for a game I plan to develop. As far as I did, I managed to set up the navigation mesh and my navmeshagents.
