Making Mountains in GIMP

[su_liam]

Nice. Very useful now. I've been playing with a little java app that does the distance filter thing. I'll rep you if it lets me.

edit:
Yay. It let me.

I'd move over to gimp altogether except for three things:
a)8-bit. I work a lot with 16-bit greyscale. I'd rather have double-precision float, but hey, reality.
b)Pen support. I can use my pen and tablet with gimp, but I can't get pressure sensitivity to work. This may be an issue with Apple's implementation of X11, but that's what I have...
c)Photoshop's more sophisticated brush attributes.
d)I know enough about Photoshop to make it dance. Learning curve is an issue.
e)Large-window greyscale erode and dilate. Only works on selections and they call it Grow and Shrink or some such, but a radius 3 Shrink is the same as a 7x7 dilate. Gimp only has 3x3 erode and dilate filters. Prettier, ultimately, but slower.

Hmm... I guess that works out to five.

And gimp also has:

Mathmap and Gluas to write your own (albeit slow running) filters!
