This generates an infinite pixelated fantasy map.

Alpha demo

Experimental approach used in spix.

1. Generate a tileable voronoi-based map (adapted from the approach by M. O’Leary)
2. Rasterize the map, rivers and cities
3. Apply tileable noise for trees, high-frequency hills, etc.
4. Store the result in a height buffer
   • Additional buffers can be used for trees / city plans / rivers

Everything is done in a progressive fashion in order to respect the real-time budget.

The approach is interactive (non-blocking, real-time generation).

Multiple enhancements would be welcome!

• Soften / fix tile borders!
  • see Tile.stepGeneration, I suspect we should work around the particular the FieldModifier.peaky step
  • in world.js, set WorldMap.DEBUG_THREE to get an idea with the 3D height map
• Fix rasterizing artifacts on rivers
• Advanced city rasterizing
• Add high altitude lakes?
