Preview? As in the heightmap? Or as in the 3D terrain? If the latter, it's what's on the screen in front of you! If the former, that's easy enough...
Working on the Save/Load/Export and file selector now. By the way, the native file format is bmp, BUT! It uses ALL 3 RGB channels rather than being greyscale. Why? Because a greyscale heightmap has 256 possible heights. A full colour heightmap, while not looking pretty in itself, generates 256x256x256 possible heights; that's 16.7 million - a lot more accurate. It's easy enough to write a function to replace LoadTerrain() and TT will generate that at the click of a button. It'll also export to traditional greyscale heightmap for the purists.
@Moses - sorry! But I did put in the readme that the save wasn't there yet :)
@ sswift - are you and SSS the same man? Or did you just like what he wrote? ;)
