Tileable Heightmap

User Code & Projects

Hi there,



I’ve made a simple subdivide and displace heightmap class with seamless edges.

I’m using it in a wrap around terrain: http://www.outshine.de/



  • size: the size must be 2^n + 1

  • roughness: how chaotic to make the terrain.

  • seed: for random number generator. same seed same map.
