landscape generator

generates a fractal landscape, running water and erosion.

features

• rain
  • rain erosion
• erosion
  • smooth out / collapse
• settling of water
• leveling of water

these features are toggled with the buttons or using the r, s, l, e keys.

landscape generation

to generate a world (2^n + 1) * (2^n + 1) using midpoint displacement.

var w = world(7);

the method uses recursion randomly generating heights as we recurse deeper

_scale = (n) => Math.exp(-n / 1.5)

• ux
  • make buttons show toggle status
  • add size, scaling and roughness controls
  • export function?
  • scaleable display (not fixed)
  • 3d representation?
• geology
  • improve algorithm for water erosion
  • improve algorithm for natural erosion
• javascript
  • optimise
  • parallel?
