## Function Documentation

void GenerateTerrainPerlin | ( |  | ) |

The main new land generator using Perlin noise.

Desert landscape is handled different to all others to give a desert valley between two high mountains. Clearly if a low height terrain (flat/very flat) is chosen, then the tropic areas wont be high enough, and there will be very little tropic on the map. Thus Tropic works best on Hilly or Mountainous.
