Perlin Noise Generator

This is a very small thing that I whipped up the other day.  It’s a Java applet that will display Perlin noise.  I’ve generated a 3D cloud of noise, and then I randomly cut a 2D slice of it when the generate button is pressed.  As such, it seems random, but it’s really not.  The algorithm is described in this paper, which is really about Simplex noise (another type of noise generation developed by Ken Perlin to replace the original Perlin noise algorithm).

I made this in order to better understand Perlin noise, since I’m going to use it in a random 3D terrain generator that I’ve been working on.

The applet can be accessed here, and the source code is available here.
