Terrain Generator 1.1

Very useful, thanks for posting this.

Any chance you could share the Source Code?   I'd love to see how your Terrain Generator works behind the scenes.

I no longer have the code, but it was last written in Delphi 7.  The algorithm is fractal in nature, using Brownian motion calculations, and uses recursion.  The output of the file has to have dimensions which are a power of 2, plus 1.  The first time through the function, the "altitudes" of the main 9 points are calculated.  The main 9 are upper-left, upper-center, upper-right, left-center, center, right-center, lower-left, lower-center, and lower-right.  The map is then divided into four quadrants and each of those is sent into the recursive function.  The function randomly calculates the "altitudes" of any unassigned points of the main 9 within the quadrant.  The recursive function divides the quadrant into four smaller quadrants, and once again sends those into the recursive algorithm.  The further away two points are, the larger the variance in "altitude" at the midpoints.  At the smallest level, a 9-pixel box is submitted to the algorithm.  Since there is no more to subdivide, the function exits.  It did not use threads, so it's kind of slow, but computers are getting faster.  The "altitude" is a value between 1 and 255, I believe, which is a color of grey.  A color map then maps these values into RGB values.  The download includes sample color maps, which are customizeable and you can add more.
