Rc
Use your fingers or mouse to control the model (hold shift key or use mouse wheel to zoom it). Canvas is matched to your browser window. Press Reset to get new terrain realization. Set correlation length Rc ≥ 16 to get fractal like terrains.

Random 2D terrain. It is remake of a Java applet see White, correlated and fractal noise. 128×128 grid is used because CPU is not very fast (for larger grids one can make easy GPU realization but 8-bit textures are not enough for accurate heights and normals again :)
