###Terrain generation algorithm using diamond-square fractal and map seed.
##How to use
WASD moves the camera position and click & drag rotates
##Why? Experiment with three.js and fractal algorithms
##How? Base algorithm is the diamond-square fractal based off Paul Boxley's excellent description here. Seed is used to feed a merseinne-twister PRNG (pseudo random number generator). A height map is generated and then rendered using three.js.
