I have been working in a project about simulations of accidents and I've been trying to find information about how to implement Navigation Mesh with jME. I found a lot of examples on internet. But they haven't helped enough. If anybody knows or have any example and explain for steps about that I really be happy.
:)The example game project that me and normen currently work on already has a working navigation mesh generator and pathfinder.
Here’s a screenshot of the generator:
Hi Momoko…
I can't see the screenshot … 
or did you forget to put it? xD
I can see it just fine.

I also attached it to the post
Could you share with me how you do it? … I mean could you explain me how you do it? Or help me with any tutorial or source code… :?
It will be available soon, included in jME3, so don't worry.
I can't explain it because it will take too long, you should read a few books instead:

Well, actually I only need to know how to generate the mesh… for any model…
I found a example
The code is:

but I wonder if there is another way to generate those points without having to make them manually for any map.
Hello,
A good place to start would be the article "polygon soup for the programmer soul" at gamasutra (www.gamasutra.com/view/feature/3000/gdc_2002_polygon_soup_for_the_.php). The author explains a method for generating navigation meshes witch is simple enough to implement it within a pair of days in jme.
Good luck!
