MapGenerator

Generate procedural geographic maps from random fields.

Map generation

The process of map generation is as follows:

1. Generate a random field, choosing from the list of available random fields
2. Normalize the field between 0 and 1
3. Smooth the field with a gaussian filter
4. Retain only the mainland above a certain threshold

Random fields

The available random fields are:

• gauss: Random gaussian field, with a given power spectrum, computed using the package powerbox
• perlin: Perlin noise, computed using the package noise
• warped_perlin: Perlin noise with domain warping, computed using the package noise
• cos: Sinusoidal noise (to be improved)
• fbm: Fractional Brownian Field
