Did anybody use navigate mesh?

[wylng]

I want to use navigate mesh  to find route, but I don't have idea how to.
how to create navigate mesh,  how to navigate through the mesh, the basic theory is clear, but implement is another thing.
Do anybody help me, I want source code and demo app
Thanks a lot

raft once made something for this purpose, but it's commercial (albeit there is a limited version available for free): http://www.jkilavuz.com/index.html.

Personally, i prefer simple uniform grids that you can traverse by using a basic A* implementation. Another option is to create a waypoint graph and make your entities move along it's edges.
