This is the editor I'm writing for my terrain engine.
Unfortunatly the editor is all OpenGL, as when it comes to making applications with buttons and menus etc. etc. my experiance hits a sudden jolted end with visual basic
Infact, its becuase of that, that I am looking for a collabarator to join me in my openGL terrain project. Specifically to help me with making a suitable editor. Then if we get along well perhaps will be asked to work on other aspects of the terrain.
How it works-
-A new flat terrain is created
-two toggle-able views a free roaming first person like view
and a more restricted top down view (with adjustable x-axis rotation and up/down movement)
-incline / decline vertex beneath 3d cursor.
-2d cursor for soon to be implimented gui
-4 ellevation height texture support.
-- soon:
-plant systems
-rain/snow stuff
-day/night system
this is my world/level editor to support my first terrain engine, so as you can guess its pretty primitive.

The top left image is before the smooth method is called after editing some of the vertices. the smooth function can be called at any time by pressing 2.
