Adjust the values if you want. to see more of the terrain, scroll with your mouse. Yes, it really does go on forever. After a lot of frustration I got this working :D felt nice once it did.I first made perlin noise than made my own version of pink noise where it generates mountainy terrain.
google helped. Surprisingly not laggy at all. (at least for me) Feb 26: Initial release as a simple perlin noise thing. Feb 27: Turned into a mountain generator. Adjusted the code so that the terrain is infinite. Feb 28?: Added water and a blue sky. March 2: Fixed zooming so it works better now. One weird thing I noticed is that no matter the seed, the center point is always sea level. I don't really mind it though.
