This are some screenshots of a little demo I did recently - The neverEngine
The neverEngine is a 3D engine I work on in my spare time.
I named this demo Terrain Generator, though editing options are very poor. I
plan to extend functionality in the near future.
Right now it's more a demo for my A Star implementation than a Terrain
The two lower images show how A Star finds its way through this little
laguna depending on the water level.
You can download this demo at my homepage http://neverEngine.com and
experiment with it.
You also find a more comprehensive ReadMe about it there.
If somebody is looking for developers - I did this as part of my
application, there is more to come.
