Random Terrain Generator

This creates a random heightfield using the fault algorithm.

This creates a random heightfield with the fault algorithm. It takes a somewhat lengthy time to finish increasing a lot with the resolution and number of blocks of the finished file. It saves it as a jpeg file. The fault algorithm is where the computer makes a random ax+by=c line and everything on one side is raised a certain amount. Everything on the other side is lowered. After around 500 passes it starts to look like terrain. In my implementation I changed it so that things were raised or lowered based on the arctangent of their distance from the line which makes it look smoother.

    Quite nice. Finding proper values to generate something good looking is kinda hard at start, could use some kind of default/example parameters set. 
    100x100 blocks 1 pixel per block (substituted by 2 in code?), 1000 passes, height variation =2, smoothness =2 give more or less terrainish look, sorta depends on luck thou.

    It is substituted by 2 because for some reason I cannot figure out it never displays anything if it is 1. I thought that I should put that in there as a precaution.
