I just added detail and made the Algorithm faster. so have fun (by saying i added detail it means i made it so it is not a line.) Download to work. (message from original) Once again, a technique for anybody to pick up: this is an algorithm for randomly generating a realistic terrain. It works by choosing a height at both ends, then splitting in the middle and changing the height in the middle, then, again by changing each half, etc. - what's called a fractal algorithm. The calculation takes time - this is scratch! You can change how much detail to calculate, and less detail is quicker. Enjoy, Charles
