Another way of thinking terrain

I going to explain.

I'm studying Geographic Information System in my academie.

We use 2 kinds of heightmaps.

- The first one is similar to the "ImageBaseHeightMap"
no problem with this one

- The other one is more complex, it's not an image, it's based on vector objects:
curves and dots with altitudes link to it.

I think if such a terrain type could be build, the JME engine could by used for
a more profesionnel use ( and for me by the way ^^ ).

If someone have time to explore things in this way, it's not a small work.

just an idea  :)
