Just for quick example, I used a standard matrix for this. It uses a fault formation method for settings heights. Quite simply, each iteration draws a random line across the matrix. All points to the left of the line are lowered, and to the right of the line are raised. Also, I have done a simple smoothing routine. It simply averages the heights of surrounding points.

Each key press equals 1 iteration.
space = fault formation pass
return = smoothing pass
shift = all random points (randomize matrix)

Thats some damn fine code, Mr Phaelex. With a little bit of smoothing help from kenmo (just a lil)

Actually that really did turn out cool for less than a day of work. A few faults, 1 or 2 smooths, and thats some fine lookin terrain.

By the way, youre like me: http://www.dannywartnaby.co.uk/rgt/index.php?board=21;action=display;threadid=3927 - you used "simple" 3 times in your post.

just a suggestion phaelax - instead of completely randomizing, just randomize up to a certain value above the initial matrix heights:



this way, it's sort of a "reverse smooth" that allows you to preserve the look, but randomize still.

lol, yes, thx kenmo. I probably would've spent all daying trying to do a gaussian blur for smoothing. I think it could've been...simple.
